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。获得其在不同条件下的应力-应变数据，经经典本构理论Arrhenius回归分析，得出纯钼高温塑性流变方程。

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. The stress-strain data under different conditions are obtained, and the classical constitutive theory Arrhenius regression analysis is used to obtain the high-temperature plastic rheological equation of pure molybdenum.
