Dissimilar metals joining, especially Aluminum (Al) to copper (Cu), have gained importance in batteries for electric vehicles. Although friction stir spot welding (FSSW) has recently been used dissimilar materials, progress very slow toward understanding the effect of temperature on diffusion condition between two materials with same FCC crystal structure. The thermo-mechanical modeling define ...

Since welding residual stress is a major factor in the generation of Primary Water Stress Corrosion Cracking (PWSCC), it is essential to examine the welding residual stress to prevent PWSCC. In order to predict this residual stress, several artificial intelligence methods have been developed and used as a powerful tool in nuclear engineering fields. In this study, two data-based models, support...

dissimilar metals friction welding of austenitic–martensitic stainless steels is commonly used in order to manufacture engine valves in the automobile industry. in this study, x53crmnnin219 (austenitic stainless steel) and x45crsi93 (martensitic stainless steel) valve steel rods were welded by friction welding process. the welded joint was then heat treated at 760 0c for 60 min. mechanical prop...

Dissimilar friction stir spot welds (FSSW) between the magnesium and aluminum alloys are joined, using a novel approach called refill welding. The present work aims to evaluate macrostructural mechanical properties of welded AZ31B AA 6061-T6 in two combinations, i.e., identical Mg-to-Mg dissimilar Mg-to-Al joints, results compared with obtained conventional hardness profiles similar had appeara...
