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 usin...

Post-processing heat treatment of additively manufactured (AM) maraging steel is an important issue in the tailoring final mechanical properties a product. Up to now, mainly precipitation hardening at temperatures 450 °C–500 °C has been studied either as-built or solution-annealed samples. This work, however, presents overview effect much broader tempering 250 °C–550 on microstructure and steel...

This study was set to fundamentally investigate the characteristics of austenite reversion occurring in maraging steels additive-manufactured by laser powder bed fusion (L-PBF). The steel samples manufactured under different L-PBF process conditions (laser power P and scan speed v) were subjected heat treatments at 550°C for various durations, compared with results austenitized water-quenched s...
