Metal Matrix Composites for High Temperature Turbine Blades.

Abstract

Results obtained during the first 12-month's work on a program to develop fiber-reinforced Fe-Cr-Al-Y composites for gas turbine applications at temperatures up to 2400F are discussed. The feasibility of using a powder metallurgy method to fabricate monolayer and multi-ply specimens was demonstrated. Composites with W-1 ThO2, Mo TZM, SiC and Al2O3 continuous filaments were evaluated. Evaluations included thermochemical compatibility studies on composites with uncoated and coated filaments and preliminary stress rupture strength determinations. (Author)
