Development of High Strength Filament Reinforced Superalloy Composites

Abstract

The report describes the progress made during FY 73 on the subject project, the objective of which is to develop high strength filament (tungsten alloys and silicon carbide) reifnroced superalloy composites with a rupture life of 100 hours under 30 ksi at 2000F. Fy 73 work has resulted in the application of investment casting to the fabrication of cobalt base composites containing W- 1%ThO2 and SiC filaments. Feasibility of the casting of a vane was also demonstrated.
