lanthana

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

稀土氧化镧掺杂钼合金中的主要韧化机制为：细晶增韧颗粒增韧。

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

采用金法制备微米尺寸米尺寸的氧化镧粒子增强钼合金。
