Abstract

The lattice strain evolution in near-β Ti-10V-2Fe-3Al during room temperature tensile loading has been characterised in the as-forged and forged and aged conditions using in-situ synchrotron X-ray diffraction. The behaviour has been modelled using a 2-phase elastic-plastic self-consistent (EPSC) model. It is found that the constrained β phase E200 increases from 45GPa in the as-forged condition to 88GPa in the forged-and-aged material. C11 — C12 increases from 12 to 47 GPa, due to the increase in β-stabiliser content, in agreement with atomistic predictions. The EPSC models are reasonably successful at reproducing the observed behaviour, but do not provide a complete description of the micromechanics of these materials.
