In this study, we aim to investigate the microstructure evolution and mechanical properties in friction welded joints of high carbon S45C steel. Thus far, S45C steel was welded with structural steel containing 0.3 wt.%C using friction welding. The microstructures in a friction welded joint were characterized by optical microscopy, scanning electron microscopy, and electron back-scattered diffraction analyses, and then compared to the microstructures of CO<sub>2</sub> arc welded S45C welds. The mechanical properties of joints welded using friction and CO<sub>2</sub> arc welding were evaluated through impact tests and Vickers hardness tests. The microstructural changes, based on the welding process, were analyzed carefully in terms of chemical composition and strain condition in welds. Finally, the relationship between microstructures and mechanical properties in welds was discussed.

The high-strength aluminum alloy is the potential candidate to replace conventional materials. It has excellent corrosion-resistant, recyclable machinability. The joining of such a type of alloy using fusion welding is very difficult. Solid-state welding, friction stir welding (FSW) has been used. However, this process has attained a maximum joint of 90% of base material strength. The drop of remaining strength is due to the formation of the temperate region in the thermo-mechanically affected area. Most of the researchers have been reported that the failure has observed at the interface. Many techniques have been followed to improve the strength at the temperate region, namely, post-weld heat treatment, backing plate change, sheet position, tool offset, etc. In this study, the shot blasting technique has been used to improve the lost strength in the soft region. From the experimental result, the joint shot-peened with steel shot yielded higher strength than the classical friction stir welded (C-FSW) joints. Moreover, the stability of the shot-peened joint has been conceived 6.9% more than the C-FSW joint.
