摘要(Abstract)：

利用Gleeble-3800热模拟试验机，对含氮的H13热作模具钢开展了不同温度以及单道次的单向压缩试验，研究了其在应变速率为0.01～10 s~(-1)、变形温度为900～1250℃条件下的热变形行为，并根据高温应力-应变曲线，运用双曲正弦函数理论建立了该钢的本构模型，并根据动态材料模型确定了其在不同应变下的热加工图。结果表明：高温热压缩变形状态下，含氮H13热作模具钢的流变应力随变形温度的升高而降低，随应变速率的降低而减小，当变形温度高于1100℃,应变速率小于0.1 s~(-1)时，含氮H13热作模具钢的流变应力曲线表现为动态再结晶特征；含氮H13热作模具钢的热变形激活能为610.23 kJ/mol,适合的热加工工艺范围为1100～1250℃,应变速率0.8～10 s~(-1)。
