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 …

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

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 …

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 …

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 …

Grain refinement leads, in general, to a decreased tendency to hot tearing, a more dispersed
and refined porosity distribution, and improved directional feeding characteristics during …

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 …

Metal additive manufacturing (AM) is an innovative manufacturing technique, which builds
parts incrementally layer by layer. Thus, metal AM has inherent advantages in part …

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 …
