Abstract

Abstract: The room temperature compressive properties and microhardness of Ni3Al alloys doped with Zr were studied. For the hypostoichiometric Ni3Al alloys, the compressive strength and microhardness increased with an increase in Zr content, while softening behavior induced by doping with a certain amount of Zr was observed in hyperstoichiometric Ni3Al alloy. Possible mechanisms for the softening effect were suggested.

Key words: Ni3Al, Compressive properties, Microhardness, Softening
