Estimating single-crystal elastic constants of polycrystalline β metastable titanium alloy: A Bayesian inference analysis based on high energy X-ray diffraction and micromechanical modeling

•A Bayesian framework with high-energy X-ray diffraction and elastic self-consistent (ELSC) micromechanical model is successfully employed to identify the single-crystal elastic constants and their uncertainities in a near-β titanium alloy (Ti–10V–2Fe–3Al).•Among the different material parameters (grain texture, morphology, volume fraction) of the micromechanical model, the grains morphology was found to be significant in obtaining best fit with experimental data.•The Bayesian identified single crystal elastic constants of the β phase are C11β=92.6±19.1GPa,C12β=82.5±16.3GPa,C44β=43.5±7.1GPa accounting for prolate spheroid grains with aspect ratio of ~3.8±0.8.
