The Next New Thing
by Reed Miller
January 6, 2012
Happy New Year! A recently released book argues that
emerging technologies hold the power to elevate humankind. The focus of the
book has nothing to do with thermal processing, so I won’t promote it here. But
its thesis is hard to argue. Many (not all) emerging technologies in our
industry will help us to do things better, quicker or more efficiently.
Improved efficiencies might help us to save money or might allow our companies
to hire new people. Now that would be a good thing in this economy.
The next
new thing is always difficult to put a finger on. Government believes they are
able to pick the next new thing, but often even they (in all of their wisdom?)
get it wrong. Here are a few things with ties to our industry that just might
impact us in the months and years ahead.
DARPA
A good place to look for new ideas is research for defense
or space applications. The technology is typically cutting-edge. The Defense
Sciences Office (DSO) of DARPA is one place doing this type of work. The DSO
Materials program “seeks to advance material science on many technology
fronts.” One of these fronts is to “innovate processing methods that
dramatically reduce the cost of producing titanium metal and its alloys.” They
state their objective as follows: “This focus area includes new materials
concepts for lowering the weight and increasing the performance of aircraft,
ground vehicles and spacecraft structures.”
The goal of
DARPA’s Titanium Initiative (DTI) is to reduce production costs of titanium – a
material with excellent corrosion resistance and good ballistic properties – to
improve its usability for defense applications. The initiative research seeks
to produce titanium ore at less than $4 per pound in unmelted billet form. They
are also trying to develop a “meltless consolidation technique” to provide
low-cost billet, rod, sheet and plate products that match the properties of
traditional wrought titanium material.
In the
Multifunctional Materials and Material Systems area, projects include
revolutionary new armor systems utilizing unique high-strength steel and
polymer composite hybrid configurations for military vehicles. It doesn’t take
much imagination to see the usage of this type of material for weight reduction
in commercial vehicles. Reducing vehicle weight is a key fuel-saving measure in
automotive design.
The goal of
DARPA’s Advanced Structural Fiber (ASF) program is to develop and produce a
fiber with at least a 50% increase in strength and stiffness. It’s not hard to
see that research of this type might make some heat treatments obsolete in the
future.
DARPA’s
Structural Amorphous Metals (SAM) program is developing a new class of bulk
metallic alloys that exhibit unique combinations of mechanical properties.
Amorphous metals are noncrystalline with a “glassy” microstructure in the solid
phase. Work on amorphous-composite hybrid materials with the stiffness of
beryllium and twice the strength will be demonstrated in space applications.
Bulk amorphous alloys that exceed the strength, fatigue and corrosion
properties of titanium will be demonstrated in turbine applications.
ASM Vision 2020 Heat-Treat
Technology Roadmap
Revisiting some of the goals of Vision 2020 helps us to
see where technology developments have come in our industry and where future
technology might be needed. Energy efficiency continues to be an area of
development and interest. Advanced materials (as discussed above) will continue
to drive our industry to proactively meet the thermal-processing needs of new
materials.
Heat-treat
modeling has been the topic of a few recent articles in Industrial
Heating. The goal of outcome prediction for certain processes is already
reality. As mentioned in our April Anniversary article, sensor development
along with control technologies, particularly wireless, has been a key industry
development of the past decade. You can use the Mobile Tag at the end of the
article to take a quick tour of thermal processing’s past 100 years or so.
Alternative Energy
Alternative energy
offers our industry the potential for growth and development. Since much of it
is tied to government funding, be cautious of putting too many of your eggs in
this basket. Even wind-turbines, currently providing heat-treating work for
many, will be changing in the future as permanent-magnet generators with a
direct-drive design replace many of the gears and bearings used in most of
today’s turbines. The photo on this page shows a 2.3-MW example of one of these
next-generation wind turbines.
2012 promises to
offer opportunities and challenges as every year before it has. Being ready to
quickly and efficiently adapt to the changes will keep our industry, and your company,
on technology’s cutting edge. IH
