Modeling of Continuous Dynamic Recrystallization in Aluminum

Hallberg, Håkan LU orcid ; Wallin, Mathias LU and Ristinmaa, Matti LU orcid (2009) 11. p.59-62
Abstract
A constitutive model is presented, considering grain size refinement through continuous dynamic recrystallization together with an evolving dislocation density. The grain refinement is allowed to influence both the evolution of the dislocation density and the rate dependence of the material. The model is calibrated against experimental data on aluminum and numerical simulations of equal channel angular pressing (ECAP) material processing illustrates the capabilities of the model.
