Effects of deposition strategies on macro/microstructure and mechanical properties of wire and arc additive manufactured Ti 6Al 4V

In this study, Ti6Al4V was fabricated via wire and arc additive manufacturing (WAAM) using different deposition strategies. The effects of the travel direction and interlayer dwell time on the evolution of the prior-β grain morphology, microstructure, microhardness, and room-temperature tensile properties of the as-deposited walls were systematically investigated. The thermal and stress/strain field during the deposition process were also...
