Alpha-Ti internal strain evolution under thermomechanical loading: influence of the temperature on the plastic anisotropy

Abstract: The present proposal leans on the study of the elastoviscoplastic behavior of a polycrystalline alpha-Ti by neutron diffraction (ENGIN-X) in line with theoretical investigations (development of a more complete scale transition model): 3 dogbone-shaped samples will be charged in situ under incremental tensile strain at 4 different temperatures (ambient, 50, 150 and 250°C). To obtain a consequent data set for strain analyses, {hk.l} diffraction peaks will be followed along 2 principal directions. Collected patterns will provide the necessary data to establish a reliable model to understand and predict the thermomechanical behavior of alpha-Ti based alloys. It will especially enable the improvement of polycrystalline plasticity models through the integration of additional phenomena such as the contribution of the different deformation mechanisms to the macroscopic behavior with temperature.
