Effects of manufacturing parameters, heat treatment, and machining on the physical and mechanical properties of 13Cr10Ni1·7Mo2Al0·4Mn0·4Si steel processed by laser powder bed fusion

This study investigates the effects of build orientations, heat treatment, and mechanical machining (as processing post-processing factors) on microstructure, quasi-static properties, strain hardening, notch toughness, residual stress additive manufactured 13Cr10Ni1·7Mo2Al0·4Mn0·4Si maraging stainless steel, known commercially as CX. The material investigated in this research was processed using laser powder bed fusion (L-PBF) method manufacturing process. results show that steel CX had an anisotropic behavior under tensile loads its as-built condition. However, treatment significantly increased strength eliminated anisotropy levels. In addition, building orientation did not affect hardness, toughness. Further, retained austenite proved to have a role determining ductility hardening Finally, utilized be effective improving properties employing shorter times lower temperatures compared treatments used other studies from literature.
