摘要: 研究了稀土氧化物La₂O₃对烧结态和加工态钼材力学性能的影响.结果表明,La₂O₃不仅显着提高了烧结态和加工态钼材的强度,而且显着改善了钼的韧性,显示出综合强韧化作用.

Abstract: The influence of rare earth oxide La₂O₃ on the mechanical Properties of sintered MO bars and as-deformed Mo wires were investigated. It is shown that both strength and ductility of Mo bars and wires are greatly improved by the addition of La₂O₃, exhibiting an comprehensive strengthening and toughening effect.
