The oxidation resistance and hardness of some intermetallic compounds

Abstract

Thirty-nine intermetallic compounds have been oxidation-tested in air. These include all the known compounds in the Al-V, Al-Ni and Al-La systems, three compounds each from the Al-Mn and Cu-Zn systems, four zinc-rich transition-metal phases, six intertransition metal Laves phases, and the equiatomic compounds of antimony with aluminium, indium and nickel respectively. From the oxidation results the temperature corresponding to a weight change of 1 mg cm−2 (4h)−1 was determined by interpolation. An attempt is made to classify the compounds in terms of the ratio of this temperature to the melting point of the appropriate compound or its oxidation product. The hardness of the compounds and of additional Al-3d compounds has been estimated, and in conjunction with the oxidation data forms the basis for some observations on the nature and incidence of binary intermetallic compounds of high atomic ratio.
