摘要
在Gleeble-1500热模拟试验机上，分析钼的高温变形特征，其变形温度为1100～1400℃，变形速率为1-50s^-1，变形程度为0-0．6，并对钼板进行塑性变形抗力的研究，采用非线性回归方法建立钼板的变形抗力模型。获得了钼板的变形抗力曲线图，对不同的数学模型结构进行回归比较，提出拟合精度高的变形抗力的数学模型，该模型具有较高的精度及良好的数值稳定性。
Deformation resistance of molybdenum was studied by means of thermal simulation on Gleeble-1500 machine. The experiments were carried out under different temperatures ranging from 1100 ℃ to 1400 ℃ with the deformation velocity from 1 s^-1 to 50 s^-1 and deformation degree from 0 to 0.6. A mathematical model was put forward for the simulation of deformation resistance of molybdenum with high precision.
