英文摘要Post-heat treatments applied to laser powder bed fusion (L-PBF) additive manufactured (AM) Ti6Al4V components aim to achieve good strength-ductility matching through tailoring microstructures, including micro-structural features that span across length scales, such as prior beta phase grains, laths and precipitates. The effects of initial prior beta microstructure and subsequent solution treatment and aging (STA) on mechanical properties have been investigated. In all cases, the increase of solution temperature and aging treatment improve the strength due to solution-strengthening and precipitation-strengthening. It is confirmed that the L-PBF hereditary basket-weave microstructure possesses better tensile properties than other microstructures, with an ultimate tensile strength of 1185 +/- 6 MPa and an elongation of 15.3 +/- 0.3%. The optimal tensile properties stem from the fine structured primary alpha and transformed beta phases in the retained L-PBF prior beta grains, which are both beneficial to improving the work-hardening capacity, as well as enhancing the resistance to crack initiation and propagation. This finding can guide the optimization of mechanical properties for the L-PBF additive manufactured Ti6Al4V components.
