:通过高温力学模拟实验 ,得出了反向凝固平整轧制过程中温度、应变和应变速率对变形抗力的影响规律 ,确立了其应力 -应变模型 ,并对该模型进行了检验。结果表明 ,该模型适用于反向凝固的平整轧制过程 The influence of temperature, strain and strain rate on the deformation resistance in the process of reverse solidification was obtained through high-temperature mechanical simulation experiment. The stress-strain model was established and the model was tested. The results show that the model is suitable for the flattening process of reverse solidification
