Predicting microstructure and (micro-)texture evolution during thermo-mechanical processing requires the combined simulation of plastic deformation recrystallization. Here, a approach based on coupling full-field dislocation density crystal plasticity model cellular automaton is presented. A regridding/remeshing procedure used to transfer data between deformed mesh large-strain regular grid aut...

Partially recrystallized samples of 5352 aluminum alloy and pure titanium were sectioned and characterized with automated electron backscatter diffraction (EBSD) in a scanning electron microscope. Pixels were partitioned into recrystallized (annealed state) and unrecrystallized (deformed state) using a criterion based on the confidence index (CI) and the diffraction pattern quality (IQ). Unrecr...

The formation of a recrystallization texture is closely related to the nucleation and growth of recrystallizing grains, which may vary from grain to grain. Cube texture is a commonly observed recrystallization texture in face centered cubic metals of medium to high stacking fault energy after heavy cold-rolling and annealing. In this work, recrystallization of pure copper cold-rolled to a von M...

Abstract In previous work [1], we analyzed the recrystallization kinetics in cold-rolled AA5657 and AA5182 based on measurements of volume fraction recrystallized material, free (unimpinged) surface area density average size recrystallizing grains, plus contiguity between for a series partially samples. that work, calculated growth nucleation rates were used as basis from analysis. These two pr...

The protrusions and retrusions observed on the recrystallizing boundaries affect the migration kinetics during recrystallization. Characterization of the boundary roughness is necessary in order to evaluate their effects. This roughness has a structure that can be characterized by fractal analysis, and in this study the so-called “Minkowski sausage” method is adopted. Hereby, two cube-oriented ...

Experimental results show that voids inside additive manufactured (i.e. 3D printed) materials are unavoidable. As such samples often post-printing annealed, it is thus of interest to understand how affect boundary migration. In this work, phase field simulations recrystallization carried out for systems containing and typical inhomogeneous microstructures. The simulation the significantly shape...
