The present investigation focuses on Linear Friction Welding of a widely used Ni‐based superalloy: IN‐718. Blocks of commercial IN‐718 alloy were linear friction welded under optimized processing conditions and the evolution of the weld joint microstructure was investigated using optical and scanning electron microscopy. In particular, visual examinations and macroscopic observations of microstructure evolution in the transverse cuts through the weld revealed a specific shape and a dual nature for the flash.
