| 中文摘要: |
| 用真空电弧熔炼和真空熔融甩带法制备出厚度相同的（Fe3Co）80-xNb4Al2Si4B10Smx、Fe57-xCo18Nb4Al2Si4B15Smx和Fe42.5Co42.5Nb7-xB8Smx快淬薄带样品，借助X-ray衍射、DTA等手段研究了稀土元素Sm对快淬薄带样品的的相组成的影响以及非晶形成能力的影响.结果表明，添加Sm可以使所研究FeCo基合金的快淬薄带样品的相组成趋于简单，并且有利于提高合金的非晶形成能力.随着Sm含量的增加，快淬薄带样品的XRD图谱中对应于（CoFe）3Nb相、（FeCo）3B相以及B6(FeCo)23相的晶化峰显著减弱直至消失，α-（FeCo）相的析出也明显减弱，合金的非晶形成能力都得到了提高. |
| 英文摘要: |
| （Fe3Co）80-xNb4Al2Si4B10Smx、Fe57-xCo18Nb4Al2Si4B15Smx and Fe42.5Co42.5Nb7-xB8Smx amorphous alloy ribbons with the same thickness were prepared by vacuum arc melting and melt spinning. The influence of Sm addition on the amorphous forming ability and phase composition of as-spun alloys were studied by XRD, DTA. The results showed that, the addition of small amount of Sm improved the amorphous forming ability and made the phase composition of as-spun alloys simpler. And with the increasing of Sm contents, the intensity of the peaks corresponding to the formation of （CoFe）3Nb phase,（FeCo）3B phase and B6(FeCo)23 phase decreased and the precipitated of α-（FeCo） phase decreased apparently, while the amorphous forming ability of alloys increased. |
