Abstract

The mechanical behavior in wide temperature range of Ni3Al intermetallic with fine grain of 7 microns obtained by rapid solidification from the liquid state was investigated. Annealing allowed to modify the grains size from 10 to 50 microns. The anomalous course of tempe¬rature dependence of yield stress, hardness, strength and plasticity inherent to Ni3Al intermetallic was found during hardness measuring and bending tests in wide temperature range.
