摘要: In general, plastic strain occurs over a certain stress, called yield stress. However, it has been reported that the permanent could happen during boundary migrating even under extremely slight externally applied this study, we performed dilatometry experiments various compressive stresses and measured amount of recrystallization growth induced strain. A new empirical constitutive equation was suggested to describe plasticity. This verified by comparing calculated values with dilatometric experimental data stresses.
