Comparison of grain growth mean-field models regarding predicted grain size distributions
Marion Roth, Baptiste Flipon, Nathalie Bozzolo +1
Mean-field models have the ability to predict grain size distribution evolution occurring through thermomechanical solicitations. This article focuses on a comparison of mean-field…
Modeling CDRX and PDRX during hot forming of zircaloy-4
Victor Grand, Baptiste Flipon, Alexis Gaillac +1
A recently developed full field level-set model of continuous dynamic recrystallization is applied to simulate zircaloy-4 recrystallization during hot compression and subsequent he…
Characterization and modeling of the influence of initial microstructure on recrystallization of zircaloy-4 during hot forming
Victor Grand, Baptiste Flipon, Alexis Gaillac +1
The present article proposes a detailed study of recrystallization of zircaloy-4 under hot forming conditions by means of experimental and numerical tools. Thermomechanical tests a…
Level-Set modeling of grain growth in 316L stainless steel under different assumptions regarding grain boundary properties
Brayan Murgas, Baptiste Flipon, Nathalie Bozzolo +1
Two finite element level-set (FE-LS) formulations are compared for the modeling of grain growth of 316L stainless steel in terms of grain size, mean values and histograms. Two kind…
A 2D front-tracking Lagrangian model for the modeling of anisotropic grain growth
Sebastian Florez, Julien Fausty, Karen Alvarado +2
Grain growth is a well-known and complex phenomenon occurring during annealing of all polycrystalline materials. Its numerical modeling is a complex task when anisotropy sources su…
Comparative study and limits of different level-set formulations for the modeling of anisotropic grain growth
Brayan Murgas, Sebastian Florez, Nathalie Bozzolo +2
Four different finite element level-set (FE-LS) formulations are compared for the modeling of grain growth in the context of polycrystalline structures and, moreover, two of them a…
Statistical behaviour of interfaces subjected to curvature flow and torque effects applied to microstructural evolutions
Sebastian Florez, Karen Alvarado, Brayan Murgas +6
The movement of grain boundaries in pure metals and alloys with a low concentration of dislocations has been historically proved to follow curvature flow behavior. This mechanism i…
An examination of local strain fields evolution in ductile cast iron through micromechanical simulations based on 3D imaging
Victor Manuel Trejo Navas, Ante Buljac, François Hild +3
Microscopic digital volume correlation (DVC) and finite element precoalescence strain evaluations are compared for two nodular cast iron specimens. Displacement fields from \textit…
