Abstract

Composites containing alumina fibers in Ni3Al+B or an Ni3Al, Cr+B alloy have been prepared by several powder metallurgical processes. Tensile tests reveal some ductility and a mixed fracture mode in both monolithic and composite alloys. Previous reports of inadequate bonding of fibers in Ni3 Al+B have been confirmed.
