摘要	The coupling effect of hierarchical microstructural features at different length scales in a laser powder bed fusion (L-PBF) additively manufactured (AM) Ti-6Al-4 V alloy obfuscates the relation between microstructure and mechanical properties. In this study, the contributions of specific microstructures to the strength and plasticity are clarified by controlling hierarchical microstructures via two-stage heat treatments. It is interesting to find that the tensile strength is only determined by the content of fine alpha' martensites and the lath thickness, while the plasticity is influenced by the prior beta grain size and lath length. A synchronous improvement of strength and plasticity can be achieved by increasing the alpha' fraction and refining the prior beta grains and alpha laths. The present findings provide guidance for optimizing the overall mechanical properties of L-PBF AM fabricated titanium components.
