Post-machining of the gamma
titanium aluminide part
"Today, production of workpieces from
titanium aluminide alloys is in great demand by civil aviation.
Metallurgists and materials scientists discuss recent developments in gamma alloy technology, focusing on gamma
titanium aluminide alloys.
[24] investigated a third generation [gamma]
titanium aluminide while machining it with a cryogenic liquid nitrogen (L[N.sub.2]) cooling strategy.
Over a million jet turbine blades will be made over the next eight years, and using
titanium aluminide would reduce their weight by 45 percent over traditional components.
The advantage of
titanium aluminide is its weight being around 15% lower than titanium 6242, for example.
"The benefit of
titanium aluminide is that it's as light as aluminum and as strong as titanium," says Jim Barrett, manager of materials and technology for the Portland employer of 1,960.
