Additive manufacturing (AM) promises a major transformation for manufacturing of metallic
components for aerospace, medical, nuclear, and energy applications. This perspective …

Preventing columnar grain formation during additive manufacturing has become a
significant challenge. Columnar grains are generally regarded as unfavourable as their …

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 …

Abstract Wire-Arc Additive Manufacturing (WAAM) of large near-net-shape titanium
components has the potential to reduce costs and lead-time in many industrial sectors …

Surface deformation, applied in-process by machine hammer peening (MHP), has the
potential to refine the coarse columnar β-grain structures normally found in high deposition …

The columnar to equiaxed transition (CET) of grain structures has been a great challenge
during titanium alloy additive manufacturing (AM), especially for wire arc additive …

Functional gradient material (FGM) is an innovative material possessing gradient properties
using different premixed proportions of two or multiple metallic powders. In the present work …

Significant prior-β grain refinement of as-cast Ti–6Al–4V alloy was achieved through
additions of yttrium. Microstructural analysis revealed three mechanisms by which yttrium …

To further improve the mechanical properties of titanium matrix composite containing
relatively high fraction of TiC and Ti 5 Si 3 particles,(6.5 vol% TiC+ 3.3 vol% Ti 5 Si …

One of the long-term concerns regarding titanium alloy wires involves microstructural
inhomogeneity, mechanical instability and product unreliability in service. In this study, a …
