A bimetallic ring component is forged by a friction stir assisted forging (FS-forging). A cylindrical bimetallic blank, magnesium AZ31 cylinder (Mg core) tightly fitted inside an aluminum 6061-T6 tube (Al skin), is used. In the FS-forging, the frictional heat and stirring of rotating tool forge the blank into a desired shape, while simultaneously generate a solid-state joint between the Mg core and the Al skin, without additional external heating, as confirmed by the microstructural analysis and mechanical tests. The microstructural analysis also shows that the characteristics of the solid-state joint can be different depending on the process parameters.

通过摩擦搅拌辅助锻造（FS-锻造）锻造双金属环部件。使用圆柱形双金属毛坯，镁AZ31圆柱体（镁芯），该圆柱体紧密安装在铝制6061-T6管（铝皮）中。在FS锻造中，摩擦热和旋转工具的搅拌将坯料锻制成所需的形状，同时在Mg核和Al蒙皮之间产生固态结合，而无需额外的外部加热，这已通过微观结构分析得到证实和机械测试。微观结构分析还表明，固态接头的特性可能会根据工艺参数而有所不同。
