ENHANCING PERFORMANCE OF ADDITIVELY MANUFACTURED AISI 316L BY ROTARY SWAGING
Original language description
This work deals with the study of structure and physical properties of 316 L austenitic stainless steel prepared by additive manufacturing and subsequently processed by the technology of rotary swaging. The semi-finished products were printed on a Renishaw 3D printing machine using the SLM (Selective Laser Melting) method, during which the metal powder is gradually sintered via cladding of individual layers using a powerful laser. Subsequently, room temperature rotary swaging was applied to enhance the structure and properties of the SLM- manufactured semi-product. The structural analyses showed that the swaging process imparted significant refinement of the average grain size, which decreased down to approx. 1.3 mu m (measured as the maximum feret diameter). As regards the physical properties, the density of the as-printed, as well as swaged, samples was measured using a pycnometer. As a result of forming, better material properties, such as increased density and improved hardness, were achieved. To confirm the advantages of the proposed approach consisting of a combination of 3D printing and deformation processing, all the results were compared with those acquired for an identical stainless steel prepared by conventional casting.
