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

采用粉末法制备了微米尺寸和准纳米尺寸氧粒子增强钼合。

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

稀土氧杂钼合中主要韧机制为：细晶增韧和颗粒增韧。
