摘　　要：Fe74Al4Sn2P10Si4B4C2合金具有良好的非晶形成能力。研究了Fe74Al4Sn2P10Si4B4C2母合金棒堆焊层的组织和性能。结果表明:在非晶纳米晶基体上分布着-αFe固熔体以及析出的Fe3P、Fe2B、Fe3B、Fe3C相,堆焊层具有很高的硬度。Fe74Al4Sn2P10Si4B4C2 alloy has a high glass-forming ability. A surface welding experiment was conducted with a prealloy rod and structure and properties of the layer were studied. The results show that α-Fe solid solution is distributed in nanocrystalline and amorphous matrix and Fe3 P, Fe2 B, Fe3 B, and Fe3 C are precipitated and hence the overlay welding layer has a high hardness.
