采用传统的氢气烧结粉末冶金法制备钼镧合金，按质量百分比在钼粉中加入1 % La₂O₃后，经混料机混合均匀，进行2ｔ等静压压制，保压2 min，再进行1800 ℃氢气烧结，观察其金相组织。将坯料置于1450 ℃炉中保温15 min后进行轧制，随后逐步降温以控制晶粒长大。将锻造钼棒沿轴切成26mm长的骨头拉伸样，采用SEM（JSM-2100F）对拉伸断口进行扫描，EDS对试样的元素进行定性分析。XRD试验电压为40 KV，步长为8°/min，测试范围为10-90°。

The molybdenum-lanthanum alloy was prepared by the conventional hydrogen sintering powder metallurgy method. After adding 1 % La₂O₃ to the molybdenum powder according to the mass percentage, the alloy was mixed well by a blender, isostatically pressed at 2 T, held for 2 min, and then hydrogen sintered at 1800 ℃ to observe its metallographic organization. The billet is rolled after being held in a furnace at 1450 ℃ for 15 min, followed by gradual temperature reduction to control grain growth. The forged molybdenum rod was cut into 26 mm long bone stretching samples along the axis, and the tensile fractures were scanned by SEM (JSM-2100F) and the elements of the specimens were analyzed qualitatively by EDS. The XRD test voltage was 40 KV, the step size was 8°/min, and the test range was 10-90°.
