Optimization of parameters in rotary friction welding process of dissimilar austenitic and ferritic stainless steel using finite element analysis

Solid state joining techniques are increasingly used in different types of materials, this work TP347HFG austenitic stainless steel will be welded with HiPerFer ferritic stainless-steel alloy due to their similarity properties some extent after making heat treatment addition difference cost which save for economic reasons. In work, a three-dimensional finite element model was developed. The thermal analysis and profiles between process parameters were predicted by using an ANSYS software tool. Design experiments Anova examinate the simulation results evaluate contribution ratio each parameter on responses, while grey relational specify optimum trial. It observed that trial 11 give best (A4B2C1D1) got higher grade. concluded friction pressure time have more impact interface temperature, whereas forging affect equivalent Von-Mises stress directly. speed influence total deformation. also temperature fade out diverging toward end specimen amount decrease is less side. flash extruded from both steels approximately similar as had been achieved. investigation show 8 achieved highest (300 MPa) 7 induced lower (255 MPa), maximum deformation found 0.012 mm 16 whereas, it (0.008 mm) than allowable application. Tensile strength weld joint 80% softer base metal. hardness 156 HB.
