摘　　要：以Q235钢为对象,利用Gleeble-3500热模拟试验机研究其在不同变形工艺下的热变形本构方程。结果表明,Q235钢在不同变形工艺下的热变形本构方程受温度波动影响较大,较传统的方法测得的热变形本构方程,前者的计算结果更接近于实测值。Taking Q235 steel as research object, the thermal deformation constitutive equations of Q235 steel were investigated under different heat treatment conditions using the universal thermal simulation test machine. The results show that the temperature jump will influence the thermal deformation constitutive equations of Q235 steel, and compare to the traditional equations, the former is more close to the real measured values.
