Phase equilibria in the system zirconium-chromium-carbon

Summary Phase equilibria in the system Zr-Cr-C at 1300°C were investigated by themethods of x-ray diffraction and microstructural analyses (Fig. 2). Zirconium carbide dissolves up to 6 at.% Cr, while chromium carbides dissolve negligible amounts of zirconium. In accordance with results of a thermodynamic calculation, zirconium carbide is in equilibrium with chromium carbides, chromium, and the compound ZrCr₂.
