Friction welding is a solid-state welding method used for joining metals with different properties, providing minimal thermal deformation in welded joints. Based on this advantageous feature of friction welding, this study investigates the weldability of Ti6Al4V alloy with 316L, 316Ti, 310, 430, and 304 series stainless steels using a Cu powder interlayer. Following the experimental procedures, the microstructures of the materials were analyzed using SEM-EDX, their macrostructures were visually inspected for physical changes, microhardness measurements were taken, and tensile tests were performed. It was observed that the Cu powder interlayer significantly influenced the reactions and bonding between the materials, playing a crucial role in both microstructure and mechanical properties. In this study, successful joining results were achieved using the friction welding method, and the microstructural characteristics and mechanical performance of the welded joints were thoroughly evaluated. Upon examining the microhardness results, no significant variations in hardness values were observed on the Ti6Al4V side.
