This study investigated the ultra-low-temperature (4.2 K) tensile properties and deformation mechanisms of stainless steel 304L manufactured via laser powder bed fusion (LPBF). The LPBF were compared to those conventional assess its suitability for cryogenic applications. results revealed that exhibited a significantly higher yield strength but lower ultimate elongation than at 4.2 K. temperature dependence also favored 304L. Microstructural analysis demonstrated features high density dislocation cells nano-inclusions, contributing greater strength. Furthermore, strain-induced martensitic transformation was observed as key mechanism temperatures, where austenite transformed into both hexagonal-closed packed (HCP) body-centered cubic (BCC) martensite. Notably, BCC martensite nucleation occurred within single HCP band. These findings provide critical insights mechanical behavior temperatures potential applications in extreme environments.
