摘要
通过Gleeble-1500热模拟机对SUP9D弹簧钢进行单道次轴向压缩实验,对该钢在不同变形条件(压缩量为0.6、变形速率0.01~10 s-1)和温度下的热变形和动态再结晶行为进行分析;对所得数据进行回归拟合。得出了该钢种的变形激活能、峰值应力、高温变形本构方程、流变应力方程及温度补偿系数Z与峰值应变的关系,为该钢种的实际生产提供理论基础。
By carrying out single channel axial compression test for SUP9D spring steel on Gleeble-1500 thermal simulator,the thermal deformation and dynamic recrystallization behavior of the steels under different deformation conditions(compression deformation of 0.6,deformation rate of 0.01-10 s-1)and different temperature were analyzed.The obtained data were regression fitted.The deformation activation energy,peak stress,high temperature deformation constitutive equation,flow stress equation of the steel and the relationship between the temperature compensation coefficient Z and peak strain are obtained,which can provide theoretical basis for the practical production of the steel.
