Microstructure and residual stress improvement in wire and arc additively manufactured parts through high-pressure rolling

This work resulted in a patent (GB1209562.6). The technique has subsequently been applied to titanium additively manufactured parts through a project sponsored by EADS Innovation Works (c. £120,000). This has drastically refined the microstructure resulting in a 15% improvement in static properties and a reduction in anisotropy from over 40% to less than 1% for elongation, potentially enabling mechanical property performance parity with existing products, which has not been previously possible with additive manufacture processes.
