摘　　要：用置换溶质原子－空位复合体机制，对Ａｌ－Ｃｕ合金Ｇ．Ｐ．区异常快速形成及相应的现象进行了解释，并与过剩空位机制和位错机制进行了比较。Anomalously fast formation of G.P. zone in Al-Cu alloy could be explained satisfactorily by the mechanism of solute-vacancy complex.It gives more reasonable explanation than the excess vacancy mechanism and the dislocation mechanism do.

关 键 词：复合体机制 铝铜合金 过剩空位机制 位错机制
