Description

Tensile properties for directionally solidified (DS) eutectic alloy of a nominal composition Ni-33 Mo-5.7 Al (weight percent) have been investigated at room and elevated temperatures. The microstructure-mechanical property relationship has been studied for the as-DS and heat-treated conditions. Changes in yield strength, work hardening behavior, and fracture morphology are explained in terms of microstructural changes due to heat treatment. The yield drops are attributed to microdebonding due to segregation of impurities at the fiber-matrix interface and partly to strain aging
