Coarse columnar grains and heterogeneously distributed phases commonly form in metallic
alloys produced by three-dimensional (3D) printing and are often considered undesirable …

Additive manufacturing (AM) constitutes the new paradigm in materials processing and its
use on metals and alloys opens new unforeseen possibilities, but is facing several …

This study examines the development of crystallographic misorientation and its relations to
the solidification microstructure in Laser Powder Bed Fusion (LPBF) alloys. We performed a …

The low impact toughness of selective laser melted (SLM) Ti–6Al–4V (Ti64) is a main factor
limiting its widespread application in engineering. In this work, we've greatly improved its …

A widely used approach for extending the fatigue life of engineering steels is through the
introduction of compressive residual stress (CRS). The thermal stabilities of the introduced …

Refractory high-entropy alloys (RHEAs) have attracted considerable interest due to their
elevated melting points and exceptional softening resistance. Nevertheless, the ambient …

This review discusses the cell structure induced by additive manufacturing (AM) with a focus
on stainless steel 316L and maraging steel 18Ni-300 produced by laser powder bed fusion …

The aim of this work is to investigate the formation of an anomalously high fraction of twin
boundaries (TBs) during laser directed energy deposition (DED) of a Mg-3Al-1 Zn (wt.%) …

The formation of coarse needle-shaped α′-Ti within columnar β-Ti grains in additively
manufactured titanium alloy components is nearly unavoidable, and it can lead to …

Friction rolling additive manufacturing (FRAM) is a solid-state additive manufacturing
technology that plasticizes the feed and deposits a material using frictional heat generated …
