Abstract

Vibration absorption of the Ti-6Al-4V alloy fabricated by laser powder bed fusion additive manufacturing (LPBF-AM) was evaluated following as-built and post-heat treatment (i.e., solution treatment followed by water quenching). The base plate was heated at 50°C or 200°C during building. Results showed that the vibration absorption of the as-built Ti-6Al-4V alloy was higher when the base plate was heated at 50°C than at 200°C. Further, the vibration absorption indicated strong anisotropy, with the highest vibration absorption in the direction perpendicular to the building direction and transverse to the laser scanning direction. However, after solution treatment followed by water quenching, the anisotropy in the vibration absorption of the LPBF-AMed Ti-6Al-4V alloy practically disappeared, and relatively high values were obtained parallel to each direction.
