摘　　要：在对高强IF钢HC210IF、HC250IF热轧变形抗力热模拟试验及金相组织检测的基础上,分析了不同轧制温度对变形抗力及金相组织的影响。结果表明,高强IF钢热轧变形抗力随轧制温度的升高均呈现先递减后递增的趋势,且轧制温度在850℃时变形抗力均达到最低点;900℃高温轧制时,其微观组织中晶粒更加细小均匀,低温铁素体区轧制时晶粒粗大且大小不均。Based on the thermal simulation test and metallographic examination of high strength IF steel HC210IF and HC250IF,the influence of different rolling temperature on deformation resistance and microstructure was analyzed.The results show that the hot rolling deformation resistance of high strength decreases first and then increases with the increasing of rolling temperature,and the deformation resistance reaches the lowest point when rolling at 850℃.When rolling at 900℃,the grain in the microstructure is more fine and uniform,and the grain is coarse and uneven in low temperature ferrite area.
