Towards Suppressed Microstructural Anisotropy and Superior Mechanical Properties in Additively Manufactured Ti5553 Alloy Through Ta Doping

Laser powder bed fusion (L-PBF) of near-β titanium alloys typically produces coarse columnar grains and strong <001> textures, which induce anisotropic mechanical behavior. Here, 5 wt.% tantalum (Ta) particles were doped into Ti-5Al-5Mo-5V-3Cr (Ti-5553) powder to concurrently inhibit microstructural anisotropy and cont...
