Interpretation of X-ray stress measurement and evaluation of internal residual stresses in rolled α-Ti40 using self-consistent models

Résumé

Internal stresses due to anisotropic thermal and plastic properties were investigated in rolled $α$-titanium. The thermal stresses induced by a cooling process were predicted using a self-consistent model and compared with experimental results obtained by X-ray diffraction. A study of the elastoplastic response after uniaxial loading was performed along the rolling and the transverse direction of the sheet. Using an elastoplastic self-consistent model, the predicted results were compared with X-ray diffraction and mechanical tests. Theoretical and experimental results agree in their tendencies. The comparison between $ε_{ϕψ}$ versus $\sin^2ψ$ and simulations confirms that prismatic slip is the main active deformation mode.
