摘要
通过在Gleeble-3500热/力模拟实验机上的热压缩实验,本文研究了在不同热变形条件下X120管线钢的高温变形抗力,分析了变形程度、变形温度及变形速率与变形抗力之间的关系,最终建立了X120管线钢的热轧变形抗力数学模型,并通过回归分析验证了此模型具有较高的拟合精度。
In this paper, the high-temperature deformation resistance of X120 pipeline steel under different hot deformation conditions was studied through the hot compression test on the Gleeble-3500 thermaL/mechanics simulation test machine. The relationship among the deformation degree, deformation temperature, the deformation rate and the deformation resistance was determined. The mathematical model of the deformation resistance for X120 pipeline steel was established finally and had been proved by the regression analysis to have perfect simulating precision.
