【摘要】 用Thermecmastor-Z热加工模拟试验机研究了含碳量为0.006%的超低碳钢在两相区变形的形变特征和规律;通过测定钢的流动应力和相变行为,得到了铁素体相变区间。在此基础上,研究了不同的变形工艺对流动应力的影响,建立了流动应力数学模型,从而为预测和控制铁素体区轧制负荷提供了依据。更多还原

【Abstract】 The characterstic and regulation of deformation behavior in the dual phase region of 0.006%C ultra-low carbon steel had been investigated by using Thermecmastor-Z thermo dynamic simulator.Ferrite transformation region was determined for the deformation by measuring flowing stress and transformation behavior.Furthermore,the effect of flowing stress had been studied under different deformation condiction,and the mathematical model of flowing stress was constructed for ultra low carbon steel,which provides the evidence to predicate and control hot-rolling load at ferrite region.更多还原
