PERSPECTIVE |
| Apollo 11 Anniversary Stirs Memories
of Nb Alloy Project |
| BY:
KIRK RICHARDSON Wah Chang |
Larry Seal tilts his head, squints,
and reaches way back into his memory — 35 years.
Seal, who currently consults for Wah Chang and retired
from his role as the company’s Aerospace Machine
Shop Supervisor in 2001, remembers the early days;
back when he was a young technician, fresh out of the
Welding Technology program at the Oregon Technical
Institute, working on projects that were bigger than
his imagination.
It never quite dawned on him just how important his
job at Wah Chang was until June 20, 1969. That afternoon,
as Seal watched the Apollo 11 descend to the moon’s
surface buffeted by the thrusts of a massive (W)C-103 engine skirt that he helped
manufacture, he realized the true gravity of the moment.
“During descent and landing, I was choked with excitement, concern, and
pride in our country and Wah Chang,” says Seal. “The importance of
Wah Chang C-103 and our few days of work inspecting the skirts became very obvious
when the Lunar Lander was making its decent. I am very thankful that, as a part
of the thousands of people involved in the space program, we were able to do
our
jobs successfully.”

the C-103 skirt extending from the bottom of the
module. |
Wah Chang’s role in the space program stretches back to 1958 when the company
produced niobium-zirconium alloy tubes for an aircraft propulsion program.
In 1961, Wah Chang, realizing the need for its metals
in rocket nozzle applications, began producing tungsten
products and development of production techniques for
silver
infiltrated tungsten.
By the time the Apollo 11 was being designed and
built, the company had in-depth experience manufacturing
high temperature metals for government programs. In
fact, Wah Chang’s alloys were also used for smaller nozzle extensions to
help guide spacecraft, such as Apollo 7. According to Seal, Wah Chang employees
were working 10-12 hour shifts
six and seven days a week on national
defense orders.
“When a smaller order for C-103 (niobium alloy) sheet was received for
the space program, most employees thought it was interesting but not as critical
as the defense orders,” remembers Seal. But the company kept going the
extra mile to help out.
“A few weeks after Wah Chang delivered the C-103 sheet, we began receiving
questions on the fabrication requirements,” he says, and when the skirt
subcontractor experienced welding problems, Seal was sent to assist. ”The
subcontractor was trying to weld C-103 with stainless steel welding techniques,” he
recalls.
Eventually, “four engine skirts were produced and sent to Wah Chang, where
we x-rayed and performed dye penetrant testing on these first skirts,” according
to Seal. “We always wondered if these initial skirts flew in space or were
used for test engines.” Now he knows for certain that Wah Chang’s
metal went to the moon.
In fact, Wah Chang’s C-103 was used in both
the Command and Lunar Module rocket engine skirt extensions.
These extensions are the visible portions of
the main rocket engines on both modules.

The alloy was hand picked by NASA and associated
engineers because of its strength at high temperatures;
the ability to withstand 10,500 pounds of thrust and
temperatures
of 2,700 degrees.
Materials Consultant Clyde Forney, who worked on
the program while a salesman at Wah Chang, remembers
the project well. “The skirt needed to fold up
to meet the order criteria,” recalls Forney. “It was felt because
of the rough moon surface and the appearance of a dusty loose surface, that the
legs of the module could sink in approximately 28 inches. To accommodate the
buckling and collapse of the engine extension skirt, we designed it from three
thickness of C-103.” NASA calculated that the 29,500-lb. module would strike
the surface of the moon fairly hard after descending at a speed of roughly 10
feet per second. According to Forney, the buckling and collapse went through
testing with flying colors. Not so during the most important test. Though the
descent engine nozzle worked as designed, the landing
wasn’t without a small hitch. “The in-joke
at Wah Chang, was how over-engineered the skirt was: Because the moon surface
was hard, the legs did not sink into the surface,” says Forney. “Thereby
the steps that should have been just right with up to a 28-inch depression into
the surface, were so high that the astronauts needed to jump down onto the moon
surface,” chuckles Forney.
Today, we can look back on the Apollo mission with
amazement... and just a little inside humor. On the
35-year anniversary, the stories surrounding the
mission
and the accomplishment itself still captivate us.

Apollo 11 was not only a giant step for mankind,
but a leap for technology. “The
lunar landing inspired confidence in using C-103 rocket engines coated with silicide,” states
Seal. “Hundreds of engines have been produced for various space applications
in the years since.”
According to Ron Graham, Wah Chang’s Director of Technology and Quality, “We
are at the forefront of developing and manufacturing new lightweight, high temperature
alloys for demanding aerospace applications. These include niobium and tantalum-based
metals as well as advanced titanium alloys and titanium aluminide foils.” Applications
range from turbine compressor disks, structural, lightweight honeycomb for aircraft
engine exhaust nozzles, and attitude control thrusters for the space shuttle
to engine skirts for the second stage of the Delta II rocket. “We are proud
of our ability to produce material that meets the most demanding applications
and flies on the most exciting missions,” says Graham.
It’s a heritage that Wah Chang plans to continue building on, working with
NASA and others to produce moon-tested alloys and develop new generations of
products, whether the application is rocket nozzles for launching satellites
to orbit the earth or propelling humankind on its next voyage into space.

Q&A:
Spacebound Alloys
Which Wah Chang Nb Alloys Are Currently Used
in the Aerospace Industry? Wah Chang has been largely involved in the
development of alloys and special products for
use in the
aerospace industry since it began the development
of C-103, a niobium alloy jointly developed by
Wah Chang and Boeing Airplane Company (B.A.C.)
for use initially in space re-entry vehicles.
It is specifically chosen for thrust chambers,
nozzle skirts, thrust augmenters and scram jet
engines because it is stronger than other niobium
alloys yet retains niobium’s desirable
forming and welding properties. This niobium-hafnium-titanium
alloy retains its strength up to 2700¾F, allowing
it to be used in rocket engines and other applications
without cooling. C-103 is considered an intermediate
cost material offering cost plus benefits to
design teams.
Wah Chang makes various other alloys for the
aerospace industry. Nb1Zr is used in space propulsion
systems and heat pipe applications because of
its ability
to withstand the corrosion effects of the liquid sodium coolant used in various
space reactor designs.
Another niobium alloy, Nb55Ti (Ti45Nb in accordance
with ASTM 4982), is used for rivets in airplanes
because of its particularly high tensile strength
and
cold formability characteristics.
In addition to the three key stalwarts listed
above, Wah Chang manufactures two high strength,
low density materials: C-129Y and Cb-752. These
alloys should
be considered where higher stresses are encountered. C-129Y is niobium alloyed
with 10% tungsten, 10% hafnium and 0.1% yttrium. Cb-752 is niobium alloyed
with
10% tungsten and 2.5% zirconium.
Beyond the different niobium alloys offered,
Wah Chang makes a special grade of Tantalum — Ta10W — which
is manufactured into specialty seamless tube
for various high
temperature applications.
Cu-W, Ag-W are two composite materials that
the company manufactures for use in various aerospace
applications, such as jet engine and missile
components,
including plume deflectors for the Joint Strike Fighter and the F-22
fighter aircraft.
Why are Niobium Alloys in Particular Used in the Aerospace Industry?
Niobium is able to withstand high temperatures
and can be fabricated into desired forms, yet
is lighter and less expensive than Tantalum.
Because
niobium-based alloys, such as the ones Wah Chang develops, offer
more desirable properties
over other rocket engine design materials, they are used in most
major aerospace programs, such as lunar landing
modules, communication satellites,
the space
shuttle and various other aircraft propulsion systems.

INNOVATIONSS |
| Parr Finds Perfect Stroke with
Zirconium Putter |
| BY:
KIRK RICHARDSON Wah Chang |
Golf has always been a passion
for Don Parr, inventor of the soon to be released Iolar
Z (for zirconium) Putter. It’s as intertwined
with his life as his surname is with the game. The
native Texan has been golfing for over 50 years. “My
dad was an avid golfer and got me started when I was
10 or 12,” he says. “Fortunately, dad was
a member of a couple of nice golf clubs, so I was able
to play pretty much all I wanted and when I was in
college, I became a pretty good golfer.”
According to Parr, his current handicap varies around
the mid teens. “My
scores suffer from my practice of experimenting with different clubs and shots
when I play,” he says. The “right hander” has even taken to
chipping left-handed... with the backs of his putters.
Parr is always tinkering with things, and the zirconium
putter is his latest innovation. “The development of my putter concepts came from a confluence
of things,” he says. “I have always favored an upright heavy putter
and have, as a result, been an excellent putter.
“Then came the popular practice among the pros to swing from the shoulders
without wrist action. This is a stroke that promotes consistency. That led to
the development of the long putters (belly and chest length) and the idea of
the pendulum stroke with the grip end of the putter fixed to a point on the player’s
body.
“My concept was a design that promoted the wristless stroke and achieved
the advantages of the long putters in a traditional length. The result is a very
upright lie of 11 to 14 degrees from vertical, and a very heavy head weight of
about 400 grams,” says Parr.

| Don Parr displays his Iolar zirconium putter.
Parr says in developing the Z (as he calls it),
he shought a design that would provide a wristless
stroke and achieved the advantages of long putters. |
“What drove me to design a game improvement putter for others was seeing
otherwise good golfers struggle with what I considered the easiest part of the
game,” he continues. “I have taken great satisfaction from the fact
that my friends, equipped with one of my putters, now feel as I do — putting
is pretty damn simple. I also take note of the fact that in the pro ranks, putting
is usually the deciding factor in winning tournaments or placing high in the
money rankings. Parr’s first designs were made of titanium (Ti), but because
of its low density, the heads were aesthetically too large. “Also, Ti is
very hard compared to steel, the typical putter material,” he observes. “My
next designs were in stainless steel and worked out well; however the heads were
quite small.”
“I set out to find a material that had a density somewhere between Ti and
stainless that was not susceptible to rust or corrosion.” That led him
to explore the Internet, where he discovered zirconium and Steve Sparkowich,
Wah Chang’s Corrosion Laboratory Manager. Sparkowich answered Parr’s
questions about zirconium and provided him with contacts in Wah Chang’s
Sales and Marketing groups who helped get the project underway.
Parr is a quick learner. He discovered that zirconium,
with a density of 6.5 g/cc, fits nicely between titanium
at 4.5 and steel at 7.8. “Another advantage
of zirconium is its relative softness,” he says. “It has a very nice
feel when stroking a ball. It is also a handsome material. As far as I know there
is no other zirconium putter on the market.”
Iolar is currently looking for professional golfers
to experiment with the Z putter. “Each putter I put on the market will conform to USGA equipment
rules,” says Parr. “The Z has been informally approved and
is now at the USGA for formal approval. I am well versed in the USGA
Rules and their interpretation, and my clubs are designed to conform.”
Currently, the IOLAR No. 4 stainless putter is available
to the public through Neiman Marcus and Horchow online.
Custom orders can be requested
through
the IOLAR web site, www.iolargolf.com.
“Regarding the Z putter, we are manufacturing the club in January or February,
with the first 10 going to Wah Chang,” says Parr. The Z will be available
on Iolar’s web site and through other outlets by March, according to Parr.
The retail price will be in the neighborhood of $400.
So, what lies ahead for the inventive Texan? “I
have a number of design ideas to work on next year,” he
says. “These include additional putters
as well as special purpose irons. I will have to fit this in when
I can.” You
can be sure he’ll find the time. “What drives me is the
challenge and satisfaction in creating something for the game I have
enjoyed for so many
years.” That’s good news for golfers. For those whose
handicaps leave something to be desired, Parr’s innovations
might just prove a stroke of brilliance.

EVENTSSAFE |
| SMST Event Displays Opportunities
for NiTiNOL Applications |
| BY:
KIRK RICHARDSON Wah Chang |
At the recent Conference on
Shape Memory and Superelastic Technology (SMST 2004),
ideas for new applications flowed through the exhibition
like molten metal poured from a tundish. Applications
for shape memory metal was the hottest topic at the
Baden Baden, Germany event, with ideas ranging from
parts for wristwatches to new medical devices.
NiTiNOL, a shape memory and superelastic nickel-titanium
alloy developed by the U.S. Navy in 1959 and made by
ATI Wah Chang, is just now beginning to realize
its potential.
Traditional applications for these alloys include
biocompatible, self-expanding stents, catheter wire,
dental files, and superelastic cell phone antennas
that
bounce back to shape, even under the stress of a teenager.
These applications are possible because of NiTiNOL’s unique mechanical
properties. It all revolves around the alloy’s crystalline structure, which
is sensitive to external stress and temperature. NiTiNOL can either be produced
in superelastic or shape-memory forms.
According to one medical device manufacturer, the
mechanism responsible for both superelasticity and
shape memory is a solid-state phase transformation,
scientifically
called thermoelastic martensitic transformation. Simply put, when produced
to provide the shape memory effect, NiTiNOL can be
deformed, hold its new shape,
then revert back to its original shape when heated above its transitional temperature
(usually between -50¾C - 166¾C). When produced for superelasticity, the alloy
is capable of absorbing strain energy and releasing it as the applied strain
is removed. In this case, a superelastic, spring-back effect occurs without
changing temperatures of NiTiNOL. (For a deeper, more
technical explanation, visit www.nitinol.com.)
Wah Chang has been active in this dynamic product
line since the early 1990s. It has not been an easy
effort as NiTiNOL is a challenging material to produce.
The barriers to entry for a new manufacturer are significant, since compositions
need to be precise (within a couple of hundredths of a percent) and contaminants
need to be eliminated.
Over the last decade, Wah Chang’s product engineers have developed processes
and improved melting and manufacturing techniques, making the company a very
competitive player in the market. Andy Nichols, Director of Marketing at Wah
Chang, points to the company’s many advantages, including a breadth of
product line, precision bar and wire manufacturing, and the low-carbon-signature
alloys it produces using proprietary advanced melting practices.
The company’s timing couldn’t have been better. According to one
industry source, “There is a tremendous opportunity in stents and other
vessel strengtheners.” He predicts that, within five years, the percentage
of stents based on NiTiNOL could jump to 25% of the market. In 2003, 735,653
stents were sold worldwide, most in the United States. With densely populated
foreign markets like China just emerging, the potential for growth is huge.
And stents represent just one application for the
alloy within the greater medical devices market. NiTiNOL
is also used for bone anchors that expand with body
heat
and hold sutures in place, graft support systems, filters, baskets, and various
other devices for interventional procedures.
Outside the medical device market, a manufacturer
is using shape memory metal to power miniature linear
motors for consumer electronics, with hopes of supplying
solutions to manufacturers of disk drives, printers, DVD players, and even
toys.
NiTiNOL is also used for less glamorous but useful industrial and aerospace
applications, such as smart fasteners and shape memory
couplings that join tube ends without
the added expense and permanence of welding (see accompanying photo). On the
market fringes, there is even a clothing designer in Florence, Italy using
shape memory wire in the fabric of nylon shirts. Body
heat returns the NiTiNOL wire
to its original shape within the fabric, keeping the garment wrinkle-free.

| Intrinsic Devices Unilok® NiTiNOL rings come
in an array of shapes and sizes. |
Like a nickel-titanium stent, the market for shape
memory alloys appears to be expanding with the heat
of innovation applied by creative design engineers,
scientists,
and business people. Wah Chang continues to contribute to this
success story, improving its methods of production and searching for new
applications
for this amazing specialty material that increasingly is shaping our world.

CORROSION SOLUTIONS
CONFERENCE |
| Dow’s Liening to Make Keynote
Presentation |
Wah Chang is pleased to announce
that Mr. Eugene Liening will be a Keynote Speaker for
its Fifth International Corrosion Solutions® Conference,
offering his unique perspectives on the Chemical Processing
Industries in a presentation September 12, 2005. The
conference, which covers a variety of corrosion, materials,
engineering, and testing topics, will take place in
Sunriver, Oregon from September 10-15, 2005.
Liening, the Global
Materials Engineering Discipline Team Leader at Dow
Chemical, will discuss the chemical
industry’s direction and what it means for
the technology experts who provide the industry with
product and
sales support.
In his address, Liening draws parallels between the
chemical industry and other industries that matured
in western nations and were then forced to deal with
global competition. He says that the automobile, athletic shoe and computer
industries
have all been where the chemical industry is going.
“Western chemical companies not only find themselves over-built in their
home geographies, but they also face significant cost disadvantages compared
to younger companies in rapidly developing regions of the world,” explains
Liening. “Global competition in chemicals will keep cost-control pressures
high even in a recovering economy.”
Additionally, he says, markets and raw materials
are forcing change in where chemicals are manufactured.
Manufacturing will increasingly move from North America
and Europe to Asia and the Middle East, drawn by the growing markets and lower-cost
raw materials, respectively. Joint ventures with companies native to these
regions
will be a common means to swap manufacturing technology for access to markets
and raw materials.
What does this mean to those who will be attending
the conference? It has significant implications according
to Liening. “With manufacturing moving to regions
of the world that are remote from most technology support personnel, those in
the chemical industry must plan how they want to support those locations in the
future,” he says.
Liening will discuss technology support models for
the future, the pros and cons of them, and the challenges
of making the transition from the current model to
the one that will be necessary. For example, in the near term, how does one
cope with the differences in time zones and cultures?
In the long term, can communications
technology save western technology support jobs? What are the implications
for the standard of living to
which western technology experts have
become accustomed?
Gene Liening graduated with B.S and M.S. degrees
in metallurgical engineering from The Ohio State University.
He has supported Dow Chemical’s manufacturing
operations for 30 years by consulting in a wide variety of materials engineering
technical areas. In the 1990s he led the effort to create global Dow Materials
Engineering standards. He is a Senior Materials Engineering Associate and leads
Dow’s Global Materials Engineering Discipline Team. He is also a licensed
Professional Engineer in the state of Michigan, and a NACE International Certified
Corrosion Specialist.
Liening is a past Chairman of NACE International
Unit Committees T-3L and T-14D and served as an instructor
at NACE International short courses. He has been
Dow’s representative to the Materials Technology Institute (MTI) since
1984, serving as the MTI Technical Advisory Council Chairman, as a member of
the Board of Directors, and as Chairman of the Board. He served on the External
Advisory Committee for the Materials Science and Engineering Department of The
Ohio State University from 1995 to 2001 and has numerous publications on a variety
of topics dealing with the application of materials engineering technology to
chemical processing. |
