Mechanical Stability of Retained Austenite and Texture Evolution in Additively Manufactured Stainless Steel

We employed two additive manufacturing (AM) strategies perpendicular to each other in AM stainless steel. In contrast to the vertically-built strategy, the horizontally-built one imposed higher tensile strength and ductility due to distinct transformation-induced plasticity (TRIP) behavior and a tailored initial texture oriented more favorably for deformation texture. We applied the direct-aging-treatment without solid-solution to retain unique AM microstructure and retained austenite (RA), which enhanced yield strength (+ 60.2
