摘要(Abstract)：

利用Gleeble-3500热模拟试验机研究了06Cr23Ni13不锈钢在变形温度为850～1250℃及应变速率为0.01～10 s~(-1)条件下的热变形软化行为。结果表明：当应变速率相同时，随着变形温度的升高，06Cr23Ni13不锈钢的流变应力减小；而当变形温度相同时，流变应力值随着应变速率的增大而增大。根据Arrhenius模型构建并验证了06Cr23Ni13不锈钢的本构方程。基于动态材料模型理论绘制了06Cr23Ni13不锈钢在大变形量(ε=0.6)下的热加工图。由06Cr23Ni13不锈钢的热加工图可知在变形温度为1100～1250℃、应变速率为0.01～0.05 s~(-1)的高温低应变区域内，能量耗散率η值可高达0.37～0.44,属于易加工区域，是最佳的热加工窗口。
