Special Issue Information

Dear Colleagues,

As a solid-state welding technique, friction stir welding (FSW) offers many advantages, including low distortion, lower costs, no harmful emissions, etc. With the development of highly durable welding tools and more rigid welding machines in the past two decades, the FSW technique has been expanded from aluminium alloys to metallic materials with high melting points. As one of the most widely used industrial materials, ferrous alloys have been successfully friction stir welded and exhibit better properties compared to traditional fusion welding. Generally, the FSW of steel can be performed with a peak temperature that ranges from 600 to 1200 °C to produce a favorable microstructure and improved properties of the joints. In the near future, friction stir welding and the processing of ferrous alloys show great potential to be applied in various fields, such as vehicles, shipbuilding, etc.

This Special Issue of Metals focuses on friction stir welding and the processing of ferrous alloys. Research papers and review articles related to this technique, welding tools, theory, simulation of friction stir welding and processing of ferrous alloys, including iron, carbon steel, high-strength steel, stainless steel, etc., are all welcome.

The effect of rotation speeds from 100 to 600 rpm on the microstructure and mechanical properties of friction stir welded (FSW) DP1180 steel joints was studied. The microstructure in the different weld zones were examined using optical microscopy (OM), scanning electron microscopy (SEM), electron backscattering diffraction (EBSD), and transmission electron microscope (TEM). It was found that when welded at 100 rpm, there was an obvious boundary formed in the middle of the stir zone (SZ), which divided the SZ into two parts, namely, SZ-Ⅰ and SZ-Ⅱ. Significantly refined microstructures with an average grain size of 0.41 μm and 0.28 μm were observed in SZ-Ⅰ and SZ-Ⅱ, respectively. The SZs were mainly composed of martensite when the rotation speed increased over 200 rpm. The thermo-mechanically affected zone (TMAZ) of all joints was composed of martensite and ferrite. Microhardness tests showed that the minimum microhardness of heat affected zone (HAZ) of all joints was between 280–300 HV. It was revealed that as the rotation speed increased, the tensile strength of the joint decreased. The tensile strength of the 100 rpm joint was the highest, reaching 1094 MPa. The fracture position of the 100 rpm joint was in SZ while the fracture positions of the other joints were in HAZ. Full article
