| 摘 要： | 通过TEM分析和焊丝表面敷层技术,研究了熔敷金属中筐篮编织状组织特征。研究表明,筐篮编织状针状铁素体组织是由平行排列的αFe铁素体针束以近似垂直的角度结合而成。当熔敷金属中w(Ni)从1.90%增加到2.49%,w(Cr)从1.1%减少到0.8%时,熔敷金属中筐篮编织状组织的含量有所提高。

| Abstract: | In this paper,the microstructure of acicular ferrite in deposited metal are analyzed by means of TEM and covering solid wire technology.The results show that the acicular ferrite with basket-weave morphology consists of the ferrite laths in parallel packets which appear as a 90-deg interlocking pattern. With the increase of Ni content(from 1.90% to 2.49%) and decrease of Cr content(from 1.1% to 0.8%),the fraction of the acicular ferrite with basket-weave morphology increases in deposited metal. |
