The transformations in TiRh and the effect of replacement of rhodium in TiRh by cobalt and nickel have been studied. TiRh undergoes two structural transformations which are of first order, exhibit thermoelastic properties and persist in the Ti-Rh-Co and Ti-Rh-Ni ternary alloys. Stabilization of the high temperature phase of TiRh of B2 type crystal structure down to room temperature can be achieved by substitution of cobalt at about 15 at.% and of nickel at about 20 at%. The TiCo-TiRh and TiNi-TiRh sections of the corresponding ternary systems are found to be quasi-binary.
