Additive manufacturing and friction welding

Study of a hybrid manufacturing approach, where 316L stainless steel is first produced using L-PBF technology and subsequently joined via friction welding. This process results in three distinct zones: the weld zone, the thermomechanical affected zone, and the base metal zone. While the base metal zone exhibits a coarser microstructure, grain refinement is observed as we move toward the weld zone. The objective is to do XRD to identify the welding zone, and then scanning 3DXRD to get the different phases. Some DCT might also be interesting
