采用金堆城钼业股份有限公司提供的常规粒度（纯度大于99.95％，直径约3.5 μm）纯钼粉，经还原后在YT79-500液压机对钼粉进行180 MPa冷等静压成坯，随后在中频氢气气氛烧结炉内进行固相分段式烧结，烧结温度为1880°C。将制得的烧结坯经线切割，获得尺寸为 8×12 mm的圆柱形试样，不少于16个。每个圆柱形试样均经过端面打磨以保证良好接触摩擦条件。经加热炉加热后分别在四个不同温度（1150 °C，1200 °C，1250 °C，1300 °C）和四个不同应变速率（0.01 s^-1，0.1 s^-1，1 s^-1，10 s^-1）组合条件下进行单道次热压缩测试，应变量均为60%，共计16组。借助动态材料模型（DMM）分析不同加工参数下钼的微观演变机理，借助热加工图得出合理的初始加工条件，选取不同的加工试样，沿其径向切割进行微观金相观察，以验证模型的可靠性。

The pure molybdenum powder with conventional particle size (purity greater than 99.95%, diameter about 3.5 μm) provided by Jinduicheng Molybdenum Industry Co., Ltd. was used to perform 180 MPa cold isostatic pressing of the molybdenum powder into a compact after reduction in a YT79-500 hydraulic press, and then The solid phase sintering is carried out in an intermediate frequency hydrogen atmosphere sintering furnace, and the sintering temperature is 1880°C. The prepared sintered billet was cut by wire to obtain no less than 16 cylindrical specimens with a size of 8×12 mm. Each cylindrical specimen is polished on the end face to ensure good contact and friction conditions. After being heated by a heating furnace, it is heated at four different temperatures (1150 °C, 1200 °C, 1250 °C, 1300 °C) and four different strain rates (0.01 s-1, 0.1 s-1, 1 s-1, 10 s-1) A single-pass thermal compression test is carried out under combined conditions, and the strain amount is 60%, a total of 16 groups. Analyze the microscopic evolution mechanism of molybdenum under different processing parameters with the help of dynamic material model (DMM), obtain reasonable initial processing conditions with the help of thermal processing diagrams, select different processing samples, and cut along the radial direction for microscopic metallographic observation to verify The reliability of the model.
