摘　　要：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 the non-linear rheological model of Al-Cu alloy in the solid-liquid coexistence zone has been established.Comparison has been made with the linear model.The results show that in the vicinity of the frant- ure stress and with increase creep,the non-linear character of the model becomes obvious.
