Reinforced Cobalt Alloy Composite for Turbine Blade Application.

Abstract

A composite of 0.42 V(f)W-2% ThO2 filament reinforced cobalt base alloy has been developed. It can be fabricated by convential investment casting process, has a 1093 C (2000 F), 100 hr. stress-to-rupture of 206 MN/sq M (30Ksi), and a charpy impact strength of 280.0 in-lb at 835 C as compared with 20.6 in-lb for the unreinforced alloy. Also the feasibility of casting a prototype first stage blade of JT9D engine has been demonstrated. (Author)
