Abstract

The phase equilibria of Mg-rich Mg–Mn–Zn alloys are scrutinized on the basis of computational thermochemistry. The experimentally well-established facts are very well reproduced by the present calculation. The important invariant reaction involving Mg-solid solution is calculated to be a transition type reaction L+(Mg)↔αMn+Mg51Mn20 at 340.18°C. Some aspects that were incorrectly interpreted in early experimental works are pointed out and are explained by the present calculations also involving non-equilibrium effects.

Keywords: Magnesium alloys; Calphad approach; Phase diagram; Solidification
