Abstract : The high temperature phase equilibria of the Cr-Si-C and Ni-Si-C ternary systems were investigated by means of melting point, differential thermal analytical, X-ray, and metallographic techniques. Cursory investigations were also made in the Ni-Si and Ni-C binary systems. In the Cr-Si-C system, a ternary D8 sub 8-type phase, which forms two-phase equilibria with most of the other respective binary phases is present. The high temperature phase equilibria include eleven, four-phase reactions of which seven are ternary eutectics. Seven pseudo-binary eutectics also occur. The Ni-Si-C system has simple solid-state equilibria governed by the occurring binary phases. The high temperature phase equilibria of this system include seven four-phase reactions of which five are ternary eutectics and four pseudo-binary eutectics. Isothermal sections into the melting range as well as three-dimensional space models are presented for both ternary systems.
