利用热加工模拟试验机，采用等温热压缩的方法用真应力－真应变曲线研究了Ａｌ－Ｓｃ合金动态再结晶，并对试样的动态再结晶微观过程作了说明．
The dynamic recrystallization of Al-Sc alloy was studied by means of the hot-working simulation test machine using isothermal hot compression and the dynamic recrystallization microscopic process of the sample was described by the true stress-true strain curve.
