摘　　要：利用Gleeble-1500热模拟试验机对含铌低碳双相钢经单道次压缩试验的金属塑性变形抗力进行了研究。通过实测不同变形温度、应变速率和变形程度与变形抗力的关系,建立了金属塑性变形抗力的数学模型。通过对模型进行回归分析,证明该模型具有良好的曲线拟合特性,模型精度较高。The test study for plastic deformation resistance of low carbon dual phase steel with Nb and Ti was engaged in single pass compression tests by the Gleeble-1500. The deformation resistance was determined in different from deforming level, deforming rate and deforming temperature, the model of deformation resistance was established. Through regression analysis of models, this model proved to have good curve fitting characteristics, relatively high precision models.
