| 摘 要： | 对用BAg25CuZn钎料火焰和炉中钎焊1Cr18Ni9Ti不锈钢的钎缝组织及其形成过程进行了研究,对两种钎焊方法焊态和退火状态钎缝组织进行了对比分析.研究结果表明,两种钎焊方法所得到的钎缝组织均由富铜相、富银相和伪共晶组织构成,但由于两种钎焊方法的冷却速度不同,造成钎缝组织的形貌有较大差别,退火处理有利于钎缝组织均匀化.

| Abstract: | The composition and the formation of braze metal microstructure of stainless steel brazed using BAg25CuZn alloy with oxy acetylene and in a furnace were studied. The microstructures of brazing seams with two brazing methods as brazed and as annealed were analyzed. It is concluded that the microstructure of braze metal consists of rich copper phase, rich silver phase and pseudoeutectic, the cooling speed has a big effect on the microstructure of braze metal, and annealing treatment is beneficial to the homogeneity of microstructure. |
