IC10合金的动态回复/再结晶本构行为研究
Study on Dynamic Recovery/Recrystallization Constitutive Behaviors of Alloy IC10
摘要
Abstract
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 recrystalli-zation.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 ofγ′,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 experimen-tal ones,and the average relative errors at various conditions are less than 5%.关键词
