    摘要:

    采用爆炸焊接工藝對(duì)TA1管材及Al管進(jìn)行了爆炸復(fù)合。利用SEM、XRD對(duì)復(fù)合管結(jié)合區(qū)形貌及相組成進(jìn)行了研究；測(cè)試了復(fù)合管的結(jié)合強(qiáng)度及過(guò)渡區(qū)的顯微硬度，并進(jìn)行了軸向壓縮、徑向壓扁試驗(yàn)。結(jié)果表明：直線狀及波狀界面同時(shí)存在于過(guò)渡區(qū)；過(guò)渡區(qū)域出現(xiàn)了明顯的元素?cái)U(kuò)散現(xiàn)象；界面結(jié)合強(qiáng)度不低于純鋁剪切強(qiáng)度；軸向壓縮、徑向壓扁后的復(fù)合管試樣均未出現(xiàn)分層，說(shuō)明TA1/Al復(fù)合管坯界面結(jié)合性能優(yōu)異，可以承受大的塑性變形。

    Abstract:

    Aluminum tube and TA1 tube were cladded by explosive welding. The morphology and phases of the bonding interface were studied by SEM and XRD, respectively. The bonding strength and the microhardness distribution of the transition region were measured. The axial compression test and the radial flattening test were also carried out. The results indicate that the linear and the wavy bonding interface coexist. Meanwhile, obvious element diffusion occurs in the interfacial zone. In addition, the bonding strength can get no less than the shear strength of Al. No separation happens after the compression test and flattening test, indicating that the clad tube has excellent bonding properties and can endure large plastic deformation.
