摘 要: | 通过固-液掺杂法在Mo-Re合金中加入稀土La2O3纳米颗粒制备得到Mo-Re-La合金, 将Mo-Re-La合金与Mo-Re合金、纯Mo的微观组织及力学性能进行对比研究, 得到如下结论: 在纯Mo中添加低含量Re元素(质量分数3.5%) 对Mo-Re合金有明显的细晶强化效果; 将La2O3纳米颗粒加入Mo-Re合金进一步细化和强化了Mo-Re-La合金。

Abstract: | Mo-Re-La alloys were prepared by solid-liquid doping method through adding La2O3 nanoparticles into Mo-Re alloys.Microstructures and mechanical properties of Mo-Re-La alloys, Mo-Re alloys, pure Mo were investigated.The results show that, the fine grain size strengthening of Mo-Re alloys is obvious by adding Re element into pure Mo in low mass fraction of 3.5%, and the Mo-Re-La alloys are further refined and strengthened by doping La2O3 nanoparticles into Mo-Re alloys. |
