摘　　要：通过在Gleeble-3500热/力模拟实验机上的热压缩实验,研究不同热变形条件下SPHC钢的高温变形抗力,考察变形温度、应变速率及变形程度与变形抗力之间的关系,分析了SPHC钢的动态再结晶机理,最后建立了SPHC钢的变形抗力数学模型,通过回归分析可看出此模型有较高的拟合精度。The deformation resistance of SPHC steel during hot deformation was studied on Gleeble-3500, and the relationship among deformation temperature ,strain rate, degree of deformation and deformation resistance was determined. The model of deformation resistance of SHPC steel was obtained with high fitting precision.
