Abstract : A brief discussion of the various methods used to prepare both polycrystalline and single crystals of four different classes of intermetallic compounds is presented. The research centered on determining either the optimum conditions for compound preparation or on correlating the modes of deformation which the compound underwent when subjected to hardness or identation loading with the type of bonding and crystal structure. Four major groups of intermetallic compounds, were studied during the course of this project. These were: TiNi and the closely related compounds TiFe and TiCo; transition metal silicides with particular emphasis on the cobalt silicides; compounds having the nickel arsenide structure with major research being performed on NiSb; and refractory hard metals such as Mo borides, and carbides of Ta, Ti, Nb and Mo.
