| 摘 要： | 利用自制的钢流变力学测定装置，首次对碳钢铸坯凝固两相区的流变特性进行了实验研究，获得了其在不同载荷下的蠕变／反蠕变曲线，并由此确立了该合金的流变模型，结果表明：该合金在近固相线及近液相线温区为五元流变模型，而在中间温区为粘弹塑性六元流变模型，文中基于流变模型进一步获得了铸坯在凝固两相区不同阶段的蠕变方程。

| Abstract: | The rheological behavior of continuously casting carbon steel in the mushy zone has been investigated with the rheometer especially designed by authors. The temperature dependent creep/inverse creep curves of the steel in mushy state,and the models describing the rheological behavior are obtained.The results show that the steel follows a five-component elasto-viscoplastic rheological model in the quasi-liquid and the quasi-solid states near the solidus and liquidus,but a six-component model in the transition state. Accordingly,the creep equations are developed. |
