    Abstract A new in-depth evaluation of the micromechanical response of TC6 (Ti–6Al–1.5Cr–2.5Mo–0.5Fe–0.3Si) titanium alloy subjected to uniaxial tensile loading is performed based on micromechanical modeling. This evaluation includes reconstruction of the three-dimensional annealed microstructure (annealing at 800°C for 2h, then air cooled) of the alloy via dual-energy micro-computed tomography. In addition, constitutive relations of the constituent phases were determined via synchrotron-based in-situ high-energy X-ray diffraction and a self-consistent model as well as nanoindentation tests combined with finite element modeling. The results revealed that the stress concentration was translated from the primary α phase to the secondary α phase, then to the β phase. Moreover, the stress generated was re-transferred to the primary α phase when the strain was increased from 0.00 to 0.05. This transfer is indicative of crack initiation in the primary α grains.
