摘　　要：针对Ti／Cu接触反应界面层组织形貌以及生成成分与相进行研究。以Cu／Ti/Cu嵌入式整体结构试验件为试验对象。在连接温度为900℃，连接时间分别为3、5、7、10、12min的条件下进行瞬间液相扩散连接，研究接触熔化过程中，Ti／Cu扩散偶界面微观组织形貌的演变过程、界面成分变化以及相生成的规律。结果表明，在Ti中间层与Cu基体之间形成了一个成分、组织及性能与基体均不相同的过渡区，该区域对Cu／Ti／Cu整体结构的性能有较大影响。在所生成的共晶液相内，成分分布比较均匀，起伏不大，且在共晶液相出现的同时，能够很快实现成分的均匀化。This paper studies on microstructure, composition and phase of Ti/Cu contact reaction intercace layer. By using Cu/Ti/Cu sandwich structure test piece as object, the process parameters were at 900℃ for 3, 5, 7, 10, 12 minutes in contact - melting respectively, study the Ti/Cu diffusion couple＇s interface microsturcture evolution process, interface contents change and phase occur regularity of during the contact melting process. The result shows that between the Ti mid layer and Cu matrix a transition aera was froming which contents, structure and capability are all different from the matrix, this area has big influence to Cu/Ti/Cu sandwich structure. In the born eutetic liquid phase, the content distributs relative equally and at the same time of eutectic liquid phase shown the content can be uniformited quickly.
