The properties and serviceability of 3D-printed metal parts depend on a variety of attributes.
These include the chemical composition, phases, morphology, spatial distributions of grain …

As the lightest structural metal and one of the most abundant metallic elements on earth,
magnesium (Mg) has been used as an “industrial metal” for lightweighting in the …

The physics of alloy solidification during additive manufacturing (AM) in methods such as
laser powder bed fusion (LPBF), electron beam powder bed fusion (EPBF), and laser …

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

One of the less desirable aspects of fusion-based additive manufacturing is the propensity
for coarse columnar grain structures crossing build layers to form. This paper initially …

Grain structure control is challenging for metal additive manufacturing (AM). Grain structure
optimization requires the control of grain morphology with grain size refinement, which can …

The columnar to equiaxed transition (CET) of grain structures associated with processing
conditions has been observed during metallic additive manufacturing (AM). However, the …

In this work, strengthening of 316L stainless steel was achieved through addition of 1 and 3
wt% TiC nanoparticles. The TiC nanoparticles and 316L powders were mixed using low …

In additively manufactured (AM) metallic materials, the fundamental interrelationships that
exist between composition, processing, and microstructure govern these materials' …

In this work, SiC particles were added to the molten pool during WAAM of a high strength
low alloy steel. The introduction of these high melting point particles promoted grain …
