QuesTek wins SBIR award to develop castable titanium alloy

  • 17-Dec-2009 03:28 EST

QuesTek Innovations LLC was awarded a two-year Phase II Small Business Innovation Research (SBIR) project from the U.S. Army to continue to apply QuesTek’s Materials by Design technology to the design and development of a new castable titanium alloy for Army applications. The project is exploring designs that incorporate lower cost alloying components and processing steps. Alloy design activities will include minimizing sensitivity to elevated impurity levels (e.g., oxygen and iron) encountered in nonaerospace-grade stock materials. The final composition will first be produced (i.e., cast) and characterized using simplified test geometries, and then at final scale into specific Army components. A new low-cost titanium alloy may also have broad applications in defense, energy, chemical processing, marine, and transportation industry sectors. Potential applications in the off-highway and truck-and-bus sectors include parts such as exhaust manifolds, rocker arms, valve springs, suspension components, leaf springs, connecting rods, and turbocharger housing/components—anywhere corrosion resistance and weight savings are valued, said Rich Kooy, P.E., Director of Sales and Marketing for QuesTek.
