综述了快速凝固耐热铝合金中金属间化合物弥散相的研究现状 ,介绍了常见耐热铝合金中存在的弥散相、快速凝固工艺对弥散相形成的影响和弥散相的热稳定性及其影响因素。简要概述了弥散相的数量、分布。

The current status of research work on intermetallic compound dispersoid in rapidly solidified elevated temperature aluminum alloys is reviewed.The dispersoid existing in common elevated temperature aluminum alloys, effect of rapid solidification processing on the formation of dispersoid and their thermal stability are discribed. The relationship between the volume fraction, distribution, shape of dispersoid and the normal, elevated temperature mechanical properties of aluminum alloys is outlined briefly in this paper.
