本文建立了 Al—Cu 合金固液共存区的非线性流变模型.并同线性模型进行了对比。结果表明,在断裂应力附近并随蠕变量的增加,非线性流变行为显著。
In this paper, a nonlinear rheological model of Al-Cu alloy solid-liquid coexistence zone was established and compared with the linear model. The results show that the non-linear rheological behavior is obvious near the fracture stress and with the increase of creep quantity.
