Abstract

Tensile properties were investigated from room temperature to 673 K of a binary Mg–0.9 mass%Ca alloy where Mg2Ca phase was dispersed as lamella. The 0.2% proof stress significantly increased by the Mg2Ca phase in the temperature range investigated. It was suggested that strengthening by stable lamella Mg2Ca in the grains and limitation of deformation related to grain boundaries by Mg2Ca phase at grain boundaries contribute to improvement of high temperature strength for the Mg–Ca alloy.
