Abstract

Inadequate strength at elevated temperatures and low fracture toughness at ambient temperatures are the major deficiencies preventing the B2 aluminide NiAl as an advanced structural material used at high temperatures. In this study, an IP alloy with the composition of NiAl‐Cr/Nb alloy was chosen and prepared by injection casting, and its microstructural morphology and mechanical properties were investigated. The compression testing results demonstrate that the resultant alloy exhibits improved compressive ductility and yield strength at room temperature as compared with that of the same alloy prepared by conventional ingot casting.
