摘要：
The creep property in the Mg-6Al-3Ca alloy is improved by the addition of Mn. Spherical precipitates form after casting in 0.5Mn alloy. The number density and radius hardly change from the as-cast state. They are segregated to the interface of the planar Al2Ca phase, leading to strain fields around the particle. The precipitation of the Al2Ca phases and the spherical precipitates can significantly enhance the creep property. (C) 2010 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
