Abstract
- The intergranular lattice strains in the near-β titanium alloy Ti-β21S have been measured in the longitudinal and transverse directions during tensile loading using neutron diffraction. The obtained results have been modelled and explained using a two-phase elasto-plastic self-consistent model. We first identified the best set of the main model parameters (single crystal elastic constants, critical resolved shear stresses) and investigated the influence of these parameters on the behaviour of both the polycrystal and the diffracting volume. Good agreement between the experimental results and those predicted by the model was found for the macroscopic stress-strain dependencies and lattice strain developments of Ti-β21S.
