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.
