The molybdenum alloy reinforced by lanthana particles with the sizes of nanometer and micron was prepared by powder metallurgy.

采用粉末冶法制备尺寸和准纳尺寸氧化镧粒子增强钼。

The toughening mechanism in the lanthana doped molybdenum alloy mainly includes fine grain toughening and particle toughening.

土氧化镧掺杂钼中主要韧化机制为：细晶增韧和颗粒增韧。
