The sample which has retrogressive phenomenon precipitates the secondary phase during re-ageing treatment subsequently, and the reprecipitation sequence is due to the grain size caused by severe plastic deformation. There is a critical grain size below which the reprecipitation sequence changes, the heterogeneous precipitation of phase at grain boundaries would suppress precipitation of metastable phases such as GP zones and η′ phase.

强变形导致回归后的合金在再时效处理时可再次沉淀析出第二相粒子，但析出相的析出顺序与强变形后合金的晶粒尺有相关，当晶粒细化到某一临界尺寸以下时，析出顺序发生改变，非均匀形核的平衡相可抑制GP区、η′亚稳相等前期粒子的析出。
