摘要：
Various tensile experiments were conducted over the temperature range of 1073~1373 K at different strain rates. Experimental results show: dynamic recovery is the dominate behavior at 1073 K, and the dominate behavior over the temperature range of 1173~1373 K is dynamic recrystallization. The behavior mechanism was studied by transmission electron microscope(TEM) tests. And the observation results show: there are both edge and screw dislocations on the cube plane, and these dislocations have a tendency to form the subgrains at the interphase boundaries of γ', which is the dominate mechanism of recrystallization behaviors. At last, Sellars model, a most widely used macro constitutive model, was used to predict the flow behaviors of alloy IC10 over the temperature ranges from 1073 to 1373 K and under different strain rates. The predicted data fits well with the experimental ones, and the average relative errors at various conditions are less than 5%. © 2017, China Mechanical Engineering Magazine Office.
