研究指出，应变诱发再结晶对细化晶粒和提高大角度晶界分数的作用明显地影响合金的超塑性能。
It is evident that the effects of strain-induced recrystallization on grain refining and on high-angle grain boundary fraction increasing affect greatly the superplastic properties of the alloy.
小角度晶界向较大角度晶界不断转变的结果使大角度晶界数量不断增加，最终导致晶粒显著细化。
The transformation from low Angle grain boundaries to high Angle grain boundaries makes the number of high-angle grain boundaries increase continuously and finally the grains are refined markedly.
