Friction Stir Welding is a novel welding process which is one kind of solid state butt welding processes for sheet or plate used the friction phenomenon.This project deals to clarify the application of friction stir welding into metal matrix composites. Project was carried out to determine the effect of rotation speed of stir rod and traverse speed on quality of weld joints during friction stir welding process. It was found that aluminum plates could be joined without defects by this process and the good joint properties were achieved using proper welding condition of rotation speed of stir rod and traverse speed. This process can be minimized defects such as cracks and porosity which were appeared in conventional fusion welding process to aluminum. Hardness of the joint was reduced and joint efficiency was 90% to base metals. Microstructures of friction stir welded joint are similar to that of friction welding, that is fine grained structures. Metal matrix was also joined by this friction stir welding and partially successful joints were made. However it should be modified the stir rod materials for high temperature use under sever load conditions.

搅拌摩擦焊是一种新型的焊接工艺，它是利用摩擦现象对板材进行固态对接焊接的一种方法，本课题主要研究搅拌摩擦焊在金属基复合材料中的应用。研究了搅拌摩擦焊过程中搅拌棒转速和横移速度对焊接接头质量的影响。结果表明，采用该工艺可以实现铝板的无缺陷连接，在搅拌棒转速和横移速度等焊接工艺条件下，获得了良好的接头性能。该工艺可以最大限度地减少铝合金在常规熔焊过程中出现的裂纹和气孔等缺陷。接头硬度降低，接头效率为母材的90%。搅拌摩擦焊接头的显微组织与摩擦焊相似，均为细晶组织。金属基体也通过这种搅拌摩擦焊连接，并获得部分成功的接头。但在高温、重载条件下使用时，需要对搅拌棒材料进行改进。
