Effect of Calcium on Solidification Behavior of Mg-Sn based Alloys

摘要：

The effect of Ca addition on microstructure change, precipitation behaviours and mechanical properties, in the present work, of Mg-Sn based alloys were investigated. With increasing of Ca additions, size of the Mg-Sn-Ca ternary phases (A-type) with fine needle shape was decreased and volume fraction of these phase were increased. As Ca was increase from l wt.%,2 wt.%, size and volume fraction of Mg2Sn with coarse needle shape phase (B-type) was increased.However, in 3 wt.% Ca containing alloy, size of these Mg2Sn phase was smaller than that of 2 wt% Ca addition alloy and volume fraction of these phase was decreased.
