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

采用粉末冶金法制备了微寸和准寸氧子增强钼合金。

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

稀土氧掺杂钼合金中主要韧机制为：细晶增韧和颗增韧。
