Experimental determination and thermodynamic calculation of the phase equilibria in the Co–Mn–Ta system

Cuiping Wang, Cancan Zhao, Zhong Lin and Xingjun Liu

Abstract

The phase equilibria in the Co-rich corner of the Co–Mn–Ta system were investigated by means of optical microscopy, electron probe microanalysis and X-ray diffraction. Six isothermal sections in the Co-rich corner of the Co–Mn–Ta ternary system at 1300°C, 1200°C, 1100°C, 1000°C, 900°C, 800°C were experimentally determined. On the basis of previous and present experimental data of the phase equilibria, the thermodynamic assessments of the Mn–Ta binary and Co–Mn–Ta ternary systems were carried out by using CALPHAD. The thermodynamic parameters of the Mn–Ta binary and the Co–Mn–Ta ternary systems have been optimized for reproducing the experimental results in each system. An agreement between the calculated results and experimental data is obtained.
