The martensitic transformation temperature in addition to the tensile strength and oxidation resistance, were able to be estimated in the crystal structure map using both parameters of the bond order and d-orbital energy level of elements, for the design of TiNi shape memory compounds. The ternary TiNi–(Cr, Re, Fe, Cu, Al) intermetallics having the objective constructed phase, tensile strength, Ms-temperatures and oxidation resistance, were obtained successfully, by the adjustment of both parameters. It is found that the effectiveness of the d-electrons concept could be judged, for property-control of ternary TiNi intermetallics, as well as metallic materials.
