This work systematically studied the effect of volumetric energy density E on the
densification, microstructures, tensile mechanical properties, and shape memory …

As a potent grain refiner for steel casting, TiN is now widely used to refine γ-austenite in
steel additive manufacturing (AM). However, the refining mechanism of TiN during AM …

In this study, slow strain rate tensile tests under in situ hydrogen electrochemical charge are
performed to investigate the hydrogen embrittlement (HE) behavior of selective laser-melted …

Elemental-decorated dislocation cell is a specific substructure in additively manufactured
metals and alloys due to the intrinsic layer-by-layer rapid melting and solidification process …

Cellular structure is a unique microstructure characteristic of the additively manufactured
face-centered cubic phase metallic materials. It typically grows preferentially along the …

The heterogeneous trans-scale structures play important roles in achieving high strength
and toughness in austenitic stainless steels fabricated by directed energy deposition (DED) …

This study reported an effective strategy for simultaneously enhancing the strength and
hydrogen embrittlement resistance of laser-powder bed fusion (L-PBF) 18Ni300 maraging …

Plastic deformation of 3D printed components may occur when they are in use. Here we
analyze the effects of the initial 3D printed microstructure of 316 L stainless steel on the …
