Abstract Scope |
In this study, metal parts resembling tensile dog bones are additively manufactured via laser powder bed fusion, employing varied process parameters. Our primary objective is to elucidate the intricate relationship between process, structure, and properties in Stainless Steel 316L fabricated through this method. We accomplish this by elucidating and quantifying the impact of processing parameters and part-scale thermal history on microstructural evolution and mechanical properties. While previous studies have linked process parameters to flaw formation, microstructural features, and functional properties, a gap persists in understanding the underlying influence of thermal history. Thermal distribution, influenced by processing parameters, material properties, and part geometry, affects microstructure evolution and subsequently influences part properties. Thus, this paper's novelty lies in illuminating the process-thermal history-microstructure-property relationship in laser powder bed fusion. |
