摘要
钛/铝层状复合材料具有两种材料优异的特性,能够满足一些特殊工程需要。开发了热轧复合技术,成功制备了铝(1100)/钛(TA2)/铝(1100)三层复合板。研究了复合板轧制过程中的关键轧制技术参数(临界压下率和轧制复合工艺条件)。利用光学显微镜和SEM观察了钛/铝复合板及结合界面形貌,分析了不同退火温度对复合板力学性能的影响。基于实验结果,描述了影响复合板质量和有助于提高复合板结合强度的关键工艺过程。
The Ti/A1 multi-layer laminated composite materials can combine the excellent properties of two ma- terials, and satisfy some special engineering demands. The three-layer A1 （1100）/Ti （TA2）/A1 （1100） clad sheet was successfully fabricated by the hot rolling. The crucial technological parameters of manufacturing clad sheet, including the threshold roiling reduction and clad-rolling bonding conditions were investigated. The bond interfacial structure of the Ti/AI clad sheet was observed by SEM and optical microscope. The effect of annealing temperature on the me- chanical properties of clad sheet was researched. The crucial procedures of ensuring the qualities and improving the bonding strength of clad sheet were described based on the results of experiments.
