Specimens taken from extrusions of the intermetallic compounds VNi3, VNi2, and VCo3, of stoichiometric composition, were given a series of heat treatments to develop varying degrees of order. Mechanical properties of these specimens were determined at room temperature by means of compression and hardness testing. Structural examinations of these three compounds were started and X-ray diffraction, light microscopy and transmission electron microscopy provided some initial insight into their transformation behavior. The structural dependence of mechanical behavior was reviewed. In addition, preliminary work with off-stoichiometric compositions of VNi3, VNi2 and VCo3 and with stoichiometric V2Ni, V3Ni, VCo and V3Co have been carried out. Author
