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米准纳米氧化镧粒子合金。

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

稀土氧化镧掺杂合金中主要韧化机制为：细晶韧颗粒韧。
