Sigma phase in the ternary systems chromium-cobalt-copper and chromium-manganese-copper
… It was found that copper had a very limited solid solubility in the sign phase of both systems. The sigma field in the Cr-Co-Cu 1000°C. ternary isothermal comes into equilibrium with the terminal solid solutions of chromium, cobalt, and copper. In the Cr-Mn-Cu ternary isothermal section sigma …

Investigation of the phase equilibria and phase transformations associated with the Bi2Sr2CaCu2Oy superconductor
… r[subscript]2CaCu[subscript]2O[subscript]y (2212) solid solution region were performed in the TEM in order to separate intergrowth and solid solubility effects. Most of the solid solubility is accounted for by changes in the Sr and Ca concentrations. Changes in the Bi concentration account for the …
