| 摘 要： | 对新型Ni-Pd-Ag-Cr-Si钎料钎焊1Cr18Ni9Ti不锈钢的接头性能进行了分析。结果表明,新型Ni-Pd-Ag-Cr-Si钎料对1Cr18Ni9Ti不锈钢有良好的润湿性;钎焊接头中,紧靠钎缝与母材界面的是与该界面平行的长条形齿状镍钯基固溶体致密组织。这种固溶体具有较高的强度和塑性,钎缝宽度为170μm时,钎缝仍具有较高的剪切强度,利于保证钎焊不锈钢产品质量不发生重大变化。

| Abstract: | The properties of 1Cr18Ni9Ti stainless steel joints brazed by a new type of brazing alloy Ni-Pd-Ag-Cr-Si have been analyzed. The results showed that the brazing filler is well wettable for 1Cr18Ni9Ti stainless steel. In the brazing joint, the interface between the brazing seam and the base metal was a long strip of dentate nickel base solid solution compact structure parallel to the interface. The solid solution had high strength and plasticity. When the brazing seam width was 170 μm, the brazing seam still had a higher shear strength, which was beneficial to ensure the quality of the brazed stainless steel products did not change significantly. |
