The Bi-Pd and Ni-Bi binary phase equilibria at 235 °C were investigated. It was concluded that Bi2Pd, BiPd, Bi3Pd5, and BiPd3 are stable intermetallics in the Bi-Pd system and NiBi and NiBi3 are stable in the Ni-Bi system at this temperature. An isothermal cross section of the ternary Ni-Bi-Pd system at the same temperature was established experimentally. No ternary compound has been found. However, the Pd-rich corner of the phase diagram cannot be determined due to the sluggishness of the kinetics involved.
