Application of bulk deformation methods for microstructural and material property improvement and residual stress and distortion control in additively manufactured components

Colegrove, Paul A.; Donoghue, J.; Martina, Filomeno; Gu, Jianglong; Prangnell, P. B.; Honnige, Jan (Elsevier, 2016-11-08)

Many additively manufactured (AM) materials have properties that are inferior to their wrought counterparts, which impedes industrial implementation of the technology. Bulk deformation methods, such as rolling, applied ...
The effectiveness of combining rolling deformation with wire-arc additive manufacture on β-Grain refinement and texture modification in Ti-6Al-4V

Donoghue, J.; Anthonysamy, A. A.; Martina, Filomeno; Colegrove, Paul A.; Williams, Stewart W.; Prangnell, P. B. (Elsevier, 2016-02-08)

In Additive Manufacture (AM), with the widely used titanium alloy Ti–6Al–4V, the solidification conditions typically result in undesirable, coarse-columnar, primary β grain structures. This can result in a strong texture ...
