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

稀土氧镧掺杂钼合金中的主要韧为：细增韧增韧。

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

采用粉末冶金法备了微米尺寸准纳米尺寸的氧镧子增强钼合金。
