摘要
介绍了作者们近年来在稀土钼研究方面所取得的成果研究结果表明，稀土氧化物（La2O3，Y2O3）在强化钼的同时，对钼具有显著的韧化作用，即具有综合强韧化作用．稀土钼不仅是优良的结构材料，而且是优异的热阴极材料，有广泛的应用前景．
This paper describes systematically our recent researches and advances in rareearth-doped molybdenum. It is shown that no matter under the condition of roomtemperature, high temperatur or low-temperature, the strength, the embrittlementproperties of the molybdenum and its thermionic emission, are greatly improved by theaddition of La2O3. The rare earth oxides(La2O3, Y2O3) exhibit an comprenhensivesbongthening and toughening effect on molybdenum, which gets the molybdenumtoughened with more ductility and lower DBTT while the strength of molybdenumincreases. Besides it is proved that rare each-doped molybdenum has better emissionproperties and lower operating temperature than W-ThO2. The mechanisms concerned arealso discussed.
