On the response of titanium sulfocarbide to stress studied by in situ neutron diffraction and the elastoplastic self-consistent approach

In this paper we report in situ neutron diffraction results of fine-grained (8 μm) polycrystalline titanium sulfocarbide samples loaded to 700 MPa. The overall strains, and those on individual planes, are modeled via the elastoplastic self-consistent approach using elastic constants derived from ab initio calculations. Based on the results, we conclude that the response at stresses below 1 GPa, is, for the most part linear elastic and that when the theoretical elastic constants are combined with the elastoplastic self-consistent method, accurate predictions can be obtained of both the overall stress–strain curves and, more importantly, the 0 0 01, 101¯, and 101¯0 reflections.
