About the combined role of texture and grain size on hardening behavior of cp titanium sheets

Abstract : The goal of the study is to analyze the role of both the grain size distribution and the crystallographic texture on the plastic deformation. Data consist, on one hand, in tensile curves obtained for commercially pure titanium samples elaborated to correspond at several mean grain sizes and textures. Data consist, on the other hand, in calculated tensile curves using a crystal plasticity EVPSC model modified to include grain size effects. The trend for the yield stresses and the initial plateaus are satisfying showing that the effects of grain size are captured in the model. Under the conditions used in the model the hardening is however not enough grain size dependent when compared with experiments.
