Modelling of recrystallisation textures in aluminium alloys: II. Model performance and experimental validation

Effect of grain shape on the texture evolution during cold rolling of Al–Mg alloys

“…Much research effort has been devoted to the modeling of rolling and recrystallization textures, with either empirically or mathematically based and physically based models [14][15][16][17][18][19][20][21][22][23][24][25]. Deformation texture is often simulated by using the full or relaxed constraints version of the Taylor-Bishop-Hill model [14][15][16], a rate-sensitive crystal plasticity model [17,18], and finite element calculations [19].…”

In-situ annealing and computation study of cube texture development in a commercial aluminum alloy

“…The development of the cube orientation is favored in the model by a shorter incubation time than for Olga Sukhopar, Günter Gottstein: In-situ annealing and computation study of cube texture development in Al alloy grains of other orientations and growth selection (higher growth rate for grain boundaries with an orientation relationship of 408<111>). Since CORe is a pure growth model the orientation spectrum of the nuclei spectra and nucleation site density must be separately provided by the nucleation model ReNuc [39]. By adjusting the nucleation efficiency in the ReNuc model the simulated cube nucleus density can be fit to experimental results in order to adequately account for cube nucleation.…”

Recrystallization Modeling of AA8XXX Alloys with Cellular Automata Considering Recovering Kinetics

“…The deformation data is further useful to estimate the nucleation probabilities for recrystallization. Information on the efficiency of single grains for shear band nucleation and grain boundary nucleation can be obtained by applying the ReNuc model [21,22] on the GIA-3IVMþ output. The use of the GIA-Split Up model provides data on the efficiency of grains for transition band nucleation.…”

“…The use of the GIA-Split Up model provides data on the efficiency of grains for transition band nucleation. [21,22] Particle-stimulated nucleation was considered by a separate nucleation model. [23] For the consideration of particle stimulated nucleation, a particle volume fraction of 1.7 vol%, as measured in the hot-rolled state, was taken into account.…”

“…For most aluminum alloys, these are grain boundaries, shear bands, particles, and transition bands. To model the appearance of transition bands, the GIA-Split Up model [21,22] was used to describe the probability that a grain becomes unstable during deformation. It will thus split up and create at the same time a transition band, leading to transition band nucleation in the respective grain.…”
