摘要
通过TIG堆焊工艺试验,建立了填充金属含铝量与Fe-Al合金堆焊层含铝量之间的对应关系,研究了含铝量对堆焊层裂纹倾向、显微组织,力学性能及断裂特征的影响规律,确定了获得Fe3Al合金堆焊层所要求的焊丝含铝量范围,为研制开发Fe3Al堆焊焊丝提供了依据.
The corresponding relation between the Al contents in filler metal and Fe-Al clading layer was established through TIG cladding procedure tests, and the influence of Al content on the clad cracking, microstructure, mechanical property and fracture characteristics of the cladding layer was also investigated. The Al content range for FesAl formation was determined, so as to provide scientific basis for developing FesAl cladding wires.
