| Abstract Scope |
The existing additive manufacturing (AM) methods may induce different thermal histories to the parts due to their corresponding manufacturing characteristics, causing variation in the micro-/defect-structure of the material. Therefore, it is of interest to understand the micro-/defect-structure and mechanical properties (i.e., tensile and fatigue) of materials fabricated via different AM methods. This study aims to investigate process-structure-property relationships of 17-4 PH stainless steel (SS) additively manufactured via laser beam powder bed fusion (LB-PBF), laser powder directed energy deposition (LP-DED), and metal binder jetting (MBJ). The micro-/defect-structure of laser-based AM methods (i.e., LB-PBF and LP-DED) is characterized and compared to MBJ 17-4 PH SS counterparts. Eventually, the tensile behavior and fatigue performance of additively manufactured 17-4 PH SS are evaluated and compared among different AM methods, and the results are discussed with respect to the variations in the micro-/defect-structure. |
