The microstructural variations in the friction joint of 6061 aluminium-based alloy containing Al,O, particles (MMC) with AISI 304 austenitic stainless steel were observed systematically by using electron microscopy technique. It is found that the plastic deformation can be caused in the side of the stainless steel during the friction welding. The deformation characteristics and formation mechanism are different in the different zone along the weld interface. The deformation is mainly in the form of twin or and slip. A kind of transition layer which consists of the polycrystalline oxide was firstly observed directly by using transmission electron microscope (TEM ).

利用电子显微镜技术系统地观察了铝基复合材料(MMC)与奥氏体不锈钢之间摩擦焊焊接接头中的显微组织变化规律。发现强度较高的奥氏体不锈钢在焊接过程中发生了明显的塑性变形,焊接界面附近不同部位变形机制和特征不同,变形方式主要是形成形变孪晶、滑移带和位错亚结构。首次在透射电镜(TEM)下观察到了一个由微晶氧化物组成的过渡层组织。

Stirring friction welding was employed in the butt welding of the 7075 Al alloy with 8mm thickness in single pass. The desirable joint with tensile strength of 390 MPa can be achieved with the rotating speed of stirring joint at 1180r/min and welding speed at 37.5 mm/min, which is 78% of that of the matrix materials. The microstructure of the joint exhibits typical stirring friction joint structure, consisting of fine equiaxed grain with size of 6~7μm and finding the absence of enhancing phase in the welding...

Stirring friction welding was employed in the butt welding of the 7075 Al alloy with 8mm thickness in single pass. The desirable joint with tensile strength of 390 MPa can be achieved with the rotating speed of stirring joint at 1180r/min and welding speed at 37.5 mm/min, which is 78% of that of the matrix materials. The microstructure of the joint exhibits typical stirring friction joint structure, consisting of fine equiaxed grain with size of 6~7μm and finding the absence of enhancing phase in the welding nugget. Micro-hardness of the joint is symmetrically distributed along the welding line, however, the micro-hardness of TMAZ/HAZ transition zone and welding nugget zone is lower than that of the matrix materials, which should be the weak zone of the welds.

使用搅拌摩擦焊对8mm厚的7075-T7351铝合金进行了单道平板对接。结果表明,在工艺参数为搅拌头旋转速度为1180r/min、焊接速度为37.5mm/min时,可获得较好的接头,抗拉强度达到390MPa,是母材强度的78%;7075-T7351铝合金搅拌摩擦焊接头微观组织为典型的搅拌摩擦焊接头组织,焊核区为细小的等轴晶,晶粒大小为6~7μm,母材组织中的强化相在此区域消失;接头显微硬度值分布趋势沿焊缝中心两侧基本对称,热机影响区-热影响区过渡区及焊核区硬度低于母材,是焊件的薄弱环节。
