摘　　要：研究了热处理对N iA l-P合金的微观组织与力学性能的影响。实验结果表明:经热处理后,合金微观组织由挤压后的不完全再结晶转变为完全再结晶,微量的P偏聚于N iA l晶界处,并对其高温延伸率有重要影响。The effects of annealing treatment on the microstructure and mechanical properties for stoic with microalloyed P alloy were investigated. Results revealed that the microstructures of NiAl-P alloy changed extruded semi-recrystallization to the sole-recrystallization after annealing treatment and doping P segregated at boundaries, which influenced the superplastic behavior at high temperature
