摘要	The microstructure, compressive properties at different temperatures and hardness of NiAl Cr(Mo) Nb alloy prepared by injection casting were investigated. Compared with the conventionally cast alloy, the injection cast alloy exhibits a fine microstructure. i.e. the fine eutectic cell and interlamellar spacing as well as fine primary NiAl phase and NbCr2-type Laves phase due to the high cooling rate. In addition, the area fraction of eutectic cell increases due to the narrow intercellular zone. The Vickers hardness of injection cast alloy is markedly enhanced. The ductility and strength at room temperature are increased by 88%, and 30%, compared with those of conventionally cast alloy respectively. However, the high-temperature strength of injection cast alloy is not improved markedly. The elevated temperature compression deformation behavior can he properly described by power law equations.
