称取一定量球磨后的钼粉Mo-1%La₂O₃-350r和Mo-1%Mo₂C -350r。采用单向液压压制粉末，压力为300 MPa，不添加成型剂。将压坯置于箱式炉中于氢气氛围下进行烧结，烧结温度为1600 ℃，升温速率从室温至1000 ℃为10 ℃/min，1000 ℃至1500 ℃为5 ℃/min升温，1500 ℃至1600 ℃为2 ℃/min，保温时间为2 h，降温与升温速率相同，降温至700 ℃后随炉自然冷却。用阿基米德排水法测试烧结坯的密度（钼的理论密度为10.2 g/cm³），计算其相对密度。对烧结后的样品采用维氏硬度计测试硬度，取3个点的平均值。不同转速的球磨后粉末压坯在不同温度(1300℃和1600℃)烧结后，通过线切割制成26mm *3.5mm*1.5mm的骨头状拉伸样品，打磨抛光后在万能试验机上进行拉伸试验，拉伸速率为1mm/min。

A certain amount of molybdenum powders Mo-1%La₂O₃-350r and Mo-1%Mo₂C-350r were weighed and ground, and the powders were pressed by unidirectional hydraulic pressure of 300 MPa without adding molding agent. The pressed billets were sintered in a chamber furnace under hydrogen atmosphere at a sintering temperature of 1600 °C. The heating rate was 10 °C/min from room temperature to 1000 °C, 5 °C/min from 1000 °C to 1500 °C, and 2 °C/min from 1500 °C to 1600 °C. The holding time was 2 h. The cooling temperature was the same as the heating rate, and the cooling temperature was reduced to 700 °C and then cooled naturally with the furnace. The density of the sintered billets was tested by Archimedes drainage method (the theoretical density of molybdenum is 10.2 g/cm³), and the relative density was calculated. The sintered samples were tested for hardness using a Vickers hardness tester and the average value of three points was taken. After sintering at different temperatures (1300°C and 1600°C) of the ball-milled post-powder press billets at different speeds, bone shaped tensile samples of 26 mm * 3.5 mm * 1.5 mm were made by wire cutting, polished and then tested on a universal testing machine for tensile testing at a rate of 1 mm/min.
