Figure 1. Fabrication of heterostructured (HS) and homogeneous (HM) Ti. (A) Schematic illustrations of the LPBF process, rolling process, and sampling positions and shapes of the fatigue specimens; (B) OM image demonstrating the high formability of as-printed Ti along the building direction; (C) XRD patterns depicting the phase composition of as-printed and as-rolled Ti. LPBF: Laser powder bed fusion; OM: optical microscope; XRD: X-ray diffraction.
