Analysis and optimisation of parent grain reconstruction for additively manufactured Ti–6Al–4V
During solidification processing, most common titanium alloys solidify as high-temperature parent phase and it subsequently transforms into the room-temperature child phase. This parent to child transformation occurred as a solid-state transformation. Even though the parent phase is not observable…
