Grain boundary sliding is a grain-size sensitive mechanism linked with the development of superplasticity, and it enables metals to plastically deform to large strains at intermediate and high temperatures and slow strain rates. In this work, we present a novel approach to modeling the grain boundary sliding deformation mechanism within a crystal plasticity finite element framework that is able to represent the crystallography and constitutive behavior of grain boundaries using cohesive zone elements. The importance of this work is that it elucidates the amount of sliding that develops between grains during deformation and its effect on texture and grain shape evolution. In this case study, the model is applied to ultra-fine-grained copper and magnesium.
We would like this presentation to be considered for the Young Scientist Oral Presentation Competition.
