This project has been intended to develop a new joining process of metal-matrix composite by using in-situ formation technique assisted by high energy beam, such as laser beam. Main conclusions obtained are as follows,1. High energy beam joining apparatus equipped with powder feeder was developed. Groove surface of metal-matrix composite was melted by high energy beam irradiation and mixed powders with aluminum alloy and ceramics were injected into the groove through high energy beam, and then the deposition of metal-matrix composite was formed and filled the groove. Thus, metal-matrix composite plate was completely joined.2. Feasibility test of this new joining process was done to commercially available metal-matrix composite plate, 6061/Al2O3/10%, which was a 6061 aluminum alloy matrix with 10 volume % Al2O3 particles dispersed and joining parametric study to obtained a good joining was carried out.3. Macro and microscopic metallurgical studies were done to reveal the distribution of Al2O3 particles in the joining zone.4. Melting characteristics of magnesium alloy by high energy beam was investigated for the further study.

本研究旨在开发一种新的金属基复合材料连接工艺，即利用高能束（如激光束）辅助原位成形技术。主要结论如下：1.研制了带送粉装置的高能束流连接装置。利用高能束辐照熔化金属基复合材料的沟槽表面，并将铝合金和陶瓷混合粉末注入沟槽中，形成金属基复合材料沉积层，填充沟槽。从而实现了金属基复合材料板的完全连接.对市售的6061/Al 2 O3/10%金属基复合材料板（6061/Al 2 O3/10%）进行了连接工艺可行性试验，该复合材料板为6061铝合金基体，Al 2 O3颗粒弥散量为10%（体积分数），并对获得良好连接的连接参数进行了研究.通过宏观和微观金相分析，揭示了Al 2 O3颗粒在焊接区的分布.为进一步研究镁合金的熔化特性，对高能束流熔化镁合金进行了实验研究.
