摘　　要：以非晶态BNi89P(P 11%wt)箔带钎料真空钎焊成分为1Cr18Ni9Ti的不锈钢为试件,采用差热分析DTA、X射线衍射仪(XRD)、电子探针EPMA-1600以及金相显微镜等测试手段,研究在钎料液相线、固相线及固相线以下温度进行钎焊时,钎焊温度及冷却方式对钎焊接头抗拉强度和组织转变的影响。实验结果表明:随着钎焊温度的逐渐升高,钎焊接头抗拉强度逐渐增加;快速冷却方式下的钎焊接头抗拉强度明显高于随炉冷却方式下的钎焊接头抗拉强度。Regarding to the stainless steel 1Cr18Ni9Ti as test piece with amorphous BNi89P（P 11% wt） foil vacuum brazing material,by using of differential thermal analysis（DTA）,X-ray diffraction（XBD） instrument,electronic probe EPMA-1600,metallographic microscope and other measuring means,the paper describes the research focusing on the influence of brazing temperature and cooling method upon tensile strength and metallographic structure transformation of brazing joints. The examination showed the result that the tensile strength of brazing joints is gradually increased following with gradual rising of brazing temperature.The tensile strength of brazed joints under rapid cooling is obviously higher than that cooled in the furnace.
