OSTI ID:443179
A novel methodology is presented for modeling static recrystallization in metals, by combining the finite element simulation of cold deformation with the Monte Carlo simulation of recovery and grain growth. A model based on crystal plasticity is used to simulate the deformation of an aggregate of grains, so as to capture the inhomogeneous deformation of individual grains, and the strain hardening and texture evolution in the aggregate. The non- uniform distributions of orientation and stored energy are then mapped onto a Monte Carlo grid for simulating static recrystallization. The method has been applied to compute the kinetics and microstructural evolution after different amounts of cold deformation, and leads to improved predictions due to use of more realistic data in the Monte Carlo simulations.
