| 摘 要： | 通过ＯＭ，ＳＥＭ，ＸＲＤ，ＥＤＭＡ等分析测试手段，对膝用Ｃｕ箔作蹭夹层的ＴＢ２扩散焊界面组织、反应相生成及其生长规律进行了分析。仍照Ｃｕ－Ｔｉ二元相图，选择扩散焊温度分别为１１２３Ｋ，１１７３Ｋ和压力为５ＭＰａ，经３０，６９。１２０ｍｉｎ扩散焊后，Ｃｕ与Ｔｉ分别生成Ｃｕ３Ｔｉ２，ＣｕＴｉ，ＣｕＴｉ３，这三者都硬而脆，尤其是ＣｕＴｉ３的生成使界面性能严重恶化。

| Abstract: | The interfacial microstructure, the growth of reaction phases and the growth regularities of TB2 diffusion welding were analyzed by OM, SEM, XRD, EDS and EPMA, when Cu foil was employed as the sandwiched layer between two TB2 specimens. According to the binary phase diagram of Cu Ti,the temperatures of diffusion welding were selected as 1 123 and 1 173 K, respectively. After diffusion welding for 30, 60 and 120 min with the diffusion welding pressure being 5 MPa, Cu and Ti reacted to form Cu 3Ti 2,CuTi and CuTi 3,respectively, all of which are hard and brittle, especially CuTi 3 makes the shear property of interface substantially degrade. |
