Effect of Tool Geometry on the Microstructure of Friction Stir Welding of Copper and 316L Stainless Steel
Original language description
The microstructure evolution during dissimilar friction stir welding of copper with stainless steel 316L is studied. The welding is performed in transparence configuration using tools of two different geometries. The joints are characterized by optical microscopy, scanning and transmission electron microscopy, electron backscattered diffraction, and microhardness. The microstructure and crystallographic texture of base metals are significantly affected. The joint produced using a shoulder of 8 mm in diameter is characterized by a copper nugget with refined grains. The texture of copper is dominated by B/B over bar $B / bar{B}$ component of the shear texture. The steel beneath the tool shows a grain refinement with grains of sub-micron size and a texture which is close to the ideal simple shear texture. For the joint produced by the 16 mm diameter tool shoulder, the nugget consists of large grains of copper, while the steel beneath the tool shows small recrystallized grains of micrometer size. The texture in the steel is dominated by the B/B over bar $B / bar{B}$ component of the shear texture. The Cu/316L interface in both types of joint is of very good quality. In a detailed study of the interface, it is revealed that the welding of metals is achieved by mutual intense mechanical interlocking without formation of any intermetallic compounds. A dramatic influence of the tool is demonstrated on the microstructure of Cu-316L friction stir melding joints. A small tool shoulder diameter induces an overall refinement of the microstructure. A large tool shoulder diameter generates more heat, yielding a coarse-grained structure of Cu, while the grains in steel are less refined. The texture in all cases is a typical shear texture.image (c) 2024 WILEY-VCH GmbH
