Abstract To reasonably select the process parameters of the double cone specimen (DCS) during hot compression, the temperature field evolution in the resistant furnace during the heating stage of hot compression was analyzed by numerical and experimental methods. The results show that there is a significant temperature gradient between surface and center of the specimen during the heating stage, the temperature in the thermal radiant area is higher than the end face. The cooling condition of the strut has no significant effect on the temperature of the specimen, the heat is transferred from the strut to the specimen through the contact surface. Sectional heating can significantly reduce the temperature gradient and the holding time, the temperature difference of specimen is negatively related to the heat treatment time, the equilibration time is negatively related to the holding temperature.

热压缩加热阶段双锥试件和支柱温度场的演变

摘要 为合理选择双锥试件（DCS）热压缩工艺参数，采用数值和实验方法分析了热压缩加热阶段电阻炉内的温度场演化。结果表明，加热阶段试件表面与中心之间存在明显的温度梯度，热辐射区的温度高于端面。支柱的冷却条件对试样的温度没有显着影响，热量通过接触面从支柱传递到试样。分段加热可以显着降低温度梯度和保温时间，试样的温差与热处理时间呈负相关，
