Paper Title:
Ni3Al-Fe-Cr Alloy Processed by Combined Mechanical Alloying - Reactive Synthesis
  Abstract

Property modification of Ni3Al with alloying addition of Fe and Cr was investigated through MA and subsequent SHS processes. Fe addition brought about high temperature strengthening effect and formed a Ni-Fe compound in the liquid grainboudary phase of Ni3Al structure and Cr addition showed a retarded homogenization. Homogenized Ni3Al composition with Fe and Cr addition by MA and SHS showed better mechanical resistace and deformability in the compression tests at temperatures up to 800°C than the same composition processed by classical PM routes.
