Title: Microstructure characteristics near the interface of vacuum brazing of Al/Cr18-Ni8 stainless steel | ||
Author: LI YAJIANG, WANG JUAN, WU NA | ||
Abstract: The microstructure characteristics of vacuum brazing interface of Al/Cr18-Ni8 stainless steel was researched by means of SEM micro-hardness test and X-ray diffraction (XRD). The test results indicated that the adhesion brazing interface was excellent, and there was no porosity or micro-crack near the interface. The microstructure of the Al/18-8 brazing joint was mainly composed of equiaxial crystal and column crystal. The fracture morphology of the brazing joint mainly consists of coarse and gray fiber-shape fracture, and the fracture was mainly the mixed fracture of the toughness and cleavage. The brazing interface consists of δ(Al, Fe, Si) phase and α-Al (Si) solid solution, without obvious brittleness phase of the high hardness. |
