    <p>Thermal hysteresis in fusion welding causes significant weld deterioration in medium- and high-carbon steels. Therefore, the development of an effective alternative welding process is required. Friction stir welding (FSW) is a solid-state welding process performed in an atmosphere that reduces the risks associated with melting and solidification of metals, making it an effective alternative method. Furthermore, it facilitates a flexible in-process control of heat input, which can be achieved by controlling the welding parameters. Considering these, the authors conducted a series of studies to elucidate the characteristics of FSW for medium- and high-carbon steels, including high-strength tempered steels.</p><p>This paper presents the results of applying FSW to 1.4 GPa-grade tempered JIS-S55C steel plates. Five distinct weld types were created by varying the welding parameters, including tool rotation and welding speed. The temperature of the interface between the tool and in-process material was measured using a thermal imaging camera. The microstructure of the welds was evaluated using optical microscopy and field-emission scanning electron microscopy (FE-SEM) with an electron-backscatter diffraction (EBSD) measurement system. The mechanical properties of the welds were evaluated through Vickers hardness and tensile tests. Digital image correlation analysis was employed to analyze the local deformation during the tensile test.</p>

    <p>Microbiologically influenced corrosion (MIC) is the rapid deterioration of structural materials induced by the action of microorganisms in an environment. Microbial adhesion and proliferation on the material surface are precursors to corrosion initiation, and if the material is stainless steel, its open-circuit potential can be ennobled. Therefore, extensive biofilm formation on metal surfaces and the ennoblement of the open-circuit potential of corrosion-resistant steels are recognized as indicators of MIC.</p><p>Numerous laboratory-scale studies have been conducted on the correlation between microbial adhesion on materials and initiation of MIC. However, only few studies have been conducted on the correlation between metallurgical factors of structural materials and the amount of microbes or flora on the material surface in actual environments.</p><p>We conducted systematic research focused on material types or alloying elements to investigate how such metallurgical factors affect microbial activity in the field. The corrosion behavior was examined using corrosion engineering methods such as potential measurement and weight loss evaluation. Thereafter, the amounts of microbes and flora adhering to copper, carbon steel, and stainless steel coupons in freshwater were determined using a genetic analysis method. Material analysis indicated that the no rapid change in potential over time was observed for the copper specimen, which ranged from −10 to 60 mV. Moreover, minimal surface stains such as slime was observed on the surface of the copper specimen when compared to the carbon steel surface, which exhibited significant amounts of rust within one month of exposure. Microbial analysis also showed a remarkable decrease in the concentration of bacteria on the surface of the copper specimen over time. These results indicate the considerable potential for the use of copper in practical environments. Thus, this study has captured the growth of microorganisms and the transition of microbial community structure reflecting nutrient requirements in parallel with the process of corrosion induction in an actual environment.</p><p> </p><p>This Paper was Originally Published in Japanese in J.
