| 摘 要： | 实现了TA15钛合金T形接头的电子束焊-钎焊复合焊接.采用扫描电镜、能谱分析仪和X射线衍射分析仪等测试手段,对接头的微观组织形貌、元素成分分布和界面反应产物等进行分析研究.并分别对复合焊接头和电子束焊接头的弯曲性能进行了比较分析.结果表明,在适当的工艺条件下,可以实现TA15钛合金T形接头的电子束-钎焊复合焊接.在电子束焊缝和钎焊缝的界面处存在Cu,Ni元素的扩散和界面反应.复合焊接头的塑性要优于电子束焊,其所承受的最大压强略低于电子束焊.

| Abstract: | TA15 titanium alloy T joint obtained by EBW (electron beam welding)-brazing hybrid welding was investigated. The microstructure, element distribution and interfacial reaction were studied by means of scanning electron microscope, energy dispersive spectvoscope and X-ray diffraction.The bending properties of the joints both by hybrid electron beam welding with brazing and by electron beam welding were tested.The results showed that TA15 titanium alloy T joint was acquired by EBW-brazing hybrid welding with proper parameter.Element diffusion and interfacial reaction exist in the interface of electron beam welding and brazing.The plastic properties of the joint acquired by hybrid electron beam welding with brazing preceded the one only by electron beam welding.But the maximum intensity of pressure endured by the former is slightly lower than the later. |
