    摘要:

    本文以純鈦板與純鋁板為原料,通過爆炸復(fù)合法制備鈦/鋁/鈦層狀復(fù)合材料,之后采用熱處理以及熱壓工藝對(duì)鈦/鋁/鈦層狀復(fù)合材料進(jìn)行進(jìn)一步處理。研究結(jié)果表明：復(fù)合板界面主要由波狀界面和平直狀界面構(gòu)成,鋁元素與鈦元素在界面上發(fā)生了互擴(kuò)散,界面結(jié)合性能優(yōu)良,可以承受后續(xù)較大的二次塑性變形；熱處理后的復(fù)合板界面發(fā)生明顯擴(kuò)散,在熱處理25 h后熱壓2.5 h后鋁層完全反應(yīng),擴(kuò)散反應(yīng)層主要由TiAl3相以及Ti2Al5相構(gòu)成。

    Abstract:

    Ti/Al/Ti laminates were prepared by explosive cladding method. Then hot pressing was employed to further process the laminates. The results indicated that both linear and wavy bonding interfaces coexisted and element diffusion occurred in the interfacial zone between the titanium and aluminum layers after explosive cladding. After 25 h heat treatment and 2.5 h hot pressing, the aluminum layer was consumed completely. The reaction layer consisted of Al3Ti and Ti2Al5 phase.
