The processes of rolling and annealing of explosively welded multi-layered plates significantly affect the functional properties of the composite. In current research, fifteen-layered composite plates were fabricated using a single-shot explosive welding technique. The composites were then rolled up to 72% to reduce layer thickness, followed by annealing at 625 °C for varying times up to 100 h. Microstructure evolution and chemical composition changes were investigated using scanning electron microscopy equipped with energy-dispersive spectroscopy. The mechanical properties of the composite were evaluated by tensile testing, while the strengths of individual layers near the interface were evaluated by micro-hardness measurements. After explosive welding, the wavy interfaces were always formed between the top layers of the composite and the wave parameters decreasing as the bottom layers approach. Due to the rolling process, the thickness of Ti and Al layers decreases, and the waviness of top interfaces disappeared. Simultaneously, the necking and fracture of some Ti layers were observed. During annealing, the thickness of layers with chemical composition corresponding to the Al₃Ti phase increased with annealing time. A study of growth kinetic shows that growth is controlled by chemical reaction and diffusion. The results of micro-hardness tests showed that after annealing, a fourfold increase of hardness can be observed in the reaction layers in relation to the Ti, while in relation to Al, the increase of hardness is even 15 times greater.

爆炸焊接多层板的轧制和退火工艺显着影响复合材料的功能特性。在目前的研究中，使用单次爆炸焊接技术制造了 15 层复合板。然后将复合材料轧制至 72% 以减少层厚度，然后在 625 °C 下退火不同时间长达 100 小时。使用配备能量色散光谱的扫描电子显微镜研究微观结构演变和化学成分变化。复合材料的机械性能通过拉伸测试进行评估，而界面附近各层的强度通过显微硬度测量进行评估。爆炸焊接后，波状界面总是在复合材料的顶层之间形成，波参数随着底层的接近而减小。由于轧制过程，Ti 和 Al 层的厚度减小，顶部界面的波纹度消失。同时，观察到一些钛层的颈缩和断裂。在退火过程中，具有对应于Al的化学成分的层的厚度₃ Ti相随退火时间的延长而增加。生长动力学研究表明，生长受化学反应和扩散控制。显微硬度测试结果表明，退火后，反应层中与 Ti 相关的硬度增加了 4 倍，而与 Al 相关的硬度增加甚至增加了 15 倍。
