Abstract


Phase equilibria in the Cr–Ta and Cr–Ta–W systems were investigated using a combination of SEM, EPMA, and XRD techniques. The Cr–Ta system was refined, including the eutectic coordinates and the solubility range of the TaCr2 phase. The isothermal section of the Cr–Ta–W system at 1500 °C was constructed. The microhardness of the structural constituents in the Cr–Ta–W system was measured.

Keywords


phase equilibria; solid solutions; isothermal sections; chromium; tantalum; tungsten
