摘要
研究了过饱和ＺＡ２７的尺寸变化规律及其与组织转变的关系。过饱和ＺＡ２７在８０℃时效过程中发生迅速而明显的尺寸收缩现象，其收缩率高达０．３０％左右，随后尺寸变化很小。铜加剧尺寸收缩。η相（锌相）和ε相（ＣｕＺｎ４）从过饱和固溶体中迅速脱溶是造成尺寸收缩的原因。
It was found that the dimensions of supersaturated ZA27 reduced quickly and obviously during ageing at 80 ℃, and copper enhanced the shrinkage phenomenon. The dimensional shrinkage which occurred during ageing was due to the quick decomposition of η(Zn phases) and ε(CuZn4 phases) from supersaturated solid solution.
