【Abstract】 This paper reviews the progress in current research on NiAl intermetallic alloys systematically. Processes such as alloying, fabricating multiphase alloys and composites, directional solidification, mechanical alloying, hot pressing and hot isostatic pressing, combustion synthesis and microcrystalline coating to improve mechanical properties and high temperature oxidation resistance properties of the alloys are reviewed and discussed. Furthermore, the superplasticity and magnetic behavior of NiAl alloy are introduced.更多还原
