In this paper we report in situ neutron diffraction results of fine-grained (8 mu m) 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, 1 0 (1) over bar, and 1 0 (1) over bar 0 reflections.
