Gamma Ti aluminides for non-aerospace applications

Attempts to utilize gamma Ti aluminide in non-aerospace applications have centered on components for which weight reduction would improve overall equipment performance, namely exhaust valves and turbocharger turbines for automotive engines. As a result of extensive research that has recently been conducted on materials, manufacturing processes, and application tests for those two types of components, both have reached the point of practical utilization However, the development of low-cost manufacturing processes is still needed for expanded practical application in the future.
