High deposition rate laser directed energy deposition (HDR-DED) technology, including
powder-and wire-based laser directed energy deposition, has emerged recently to fulfil the …

Ultrafine-grained materials display almost no strain hardening, an enhanced strain rate
sensitivity and grain boundary offsets during plastic deformation. It is expected that …

The deformation-coordination ability between ductile metal and brittle dispersive ceramic
particles is poor, which means that an improvement in strength will inevitably sacrifice …

Globular α phases can significantly improve the ductility of titanium alloys. Cyclic heat
treatment (CHT) has been proved to be an effective way to induce the formation of globular α …

The coupling effect of hierarchical microstructural features at different length scales in a
laser powder bed fusion (L-PBF) additively manufactured (AM) Ti-6Al-4 V alloy obfuscates …

Abstract Effect of cooling rates, ie, air cooling and furnace cooling, after solution in α+ β
phase-field on variant selection, coarsening behavior of α phase and microstructure …

A new multiscale microstructure (NMM) comprised of long-plate α (α long) grain, fine-
equiaxed α (α fine) grain and ultrafine α (α ultra) precipitates was fabricated by hot rolling …

In this study, the fatigue behaviors of GH4169 superalloy, which possessed a gradient
nanostructure layer introduced by an ultrasonic surface rolling process (USRP) and …

Fabricating fine equiaxed grains without undesirable secondary phases is highly
challenging for additively manufactured Ti− 6Al− 4V alloy. The reference amount of Ni …

It is well-known that grain refiners can tailor the microstructure and enhance the mechanical
properties of titanium alloys fabricated by additive manufacturing (AM). However, the …
