摘要：

Planar Al2Ca phase forms on the basal plane in the as-cast AX22 and AXM220 alloys. In the AXM220 alloy, Mn is detected in the Al2Ca phase. The number density of the Al2Ca phase does not alter, irrespective of the creep deformation and Mn addition. Fine and planar precipitates appear during the creep deformation. The number density increases by the addition of Mn. The size of the precipitate is reduced by the Mn addition. The Mn addition can improve the creep property.
