摘要
研究了Ti-15Cu-15Ni钎料钎焊Ti3Al基合金接头组织构成,影响接头性能的关键因素探索,以及钎焊工艺对组织与性能的影响。研究结果表明位于钎缝中央的含有化合物的钎缝组织是影响接头性能的关键组织,采用较低温度和较短保温时间的钎焊工艺规范可获得具有较高强度的Ti3Al基合金钎焊接头。
Microstructures of brazed joints of Ti3Al-base alloy with Ti-15Cu-15Ni,the key factors affecting on properties of Ti3Al brazed joints and effect of brazing thermal cycle on microstructures and properties of joints were studied in this paper.The results indicated that the structures containing compounds in the center of the seam were the key factors for properties of joints.The Ti3Al joints brazed under lower brazing temperature and with shorter holding time possessed better properties.
