The Effect of Heat Treatment on the Microstructure and Mechanical Properties of NiAl-P Alloy

Zhang Guang-ye, Guo Jianting

Open publisher page 1 citations

Abstract

The effects of annealing treatment on the microstructure and mechanical properties for stoichiometric NiAl with microalloyed P alloy were investigated.Results revealed that the microstructures of NiAl-P alloy changed from as-extruded semi-recrystallization to the sole-recrystallization after annealing treatment and doping P segregated at the grain boundaries,which influenced the superplastic behavior at high temperature.
