Abstract

A pure copper multicrystal has been cold rolled up to an overall true strain of ∈ = 0.4. The intragranular work hardening state, due to plastic deformation, has been determined by the analysis of the X-ray peak-profiles measured within each individual grain with a high resolution diffractometer. The evolution of the intragranular dislocation density during rolling has been predicted by a finite element code, which explicitly accounts for the crystallographic nature of the material and models the plastic deformation within individual grains by crystallographic slip on specific slip systems. The experimental and the simulated data were compared in order to discuss the validity of the model developed for X-ray peak-profile analysis and the simulation work hardening law.
