A new way to include the grain shape in texture simulations with the Taylor model
The use of the Hall-Petch relation in texture simulations with the Taylor-Bishop-Hill model is proposed as a mean to take into account grain shape effect. The results are compared with those obtained with the usual and relaxed constraint Taylor model for a simple texture and the consequences for the anisotropy coefficient are investigated On propose d'utiliser la relation de Hall-Petch dans les simulations de texture a l'aide du modele de Taylor-Bishop-Hill pour prendre en compte la forme des grains. Comparaison des resultats avec ceux du modele de Taylor classique ou relaxe dans le cas d'une texture simple; consequences pour le coefficient d'anisotropie
On the Roles of Grain Size Dispersion and Microscale Hall–Petch Relation on the Plastic Behavior of Polycrystalline Metals
Micro-macro scale transition theories were essentially developed to model the inelastic behavior of polycrystals starting from the local behavior of the grains. The anisotropy of the plastic behavior of polycrystalline metals was mainly explained by taking into account the crystallographic textures. Issues like plastic heterogeneities due to grain size dispersion, involving the Hall­Petch relation at the microscale, were not often taken into account in the literature, because only the role of a mean grain size was investigated. Here, the coupled roles of grain orientation and size distributions on the plastic deformation state of grains are examined for a tensile deformed IF steel in the light of EBSD experimental data based on misorientation parameters and of a micromechanics-based modeling regarding grain and overall behaviors.

The orientation distribution function of the crystallites in cold-rolled and annealed low-carbon steel sheets
The three-dimensional orientation distribution function of the crystallites in cold-rolled end annealed low-carbon steel sheets, which is not directly measurable, has been calculated from pole figures. It consists of a continuous row of orientations together with some ideal orientation components. 
 
 
 
Die dreidimensionale Orientierungsverteilungsfunktion der Kristallite, die nicht direkt mesbar ist, wurde aus Polfiguren kaltgewalzter und gegluhter Stahlbleche berechnet. Sie besteht aus einer kontinuierlichen Reihe von Orientierungen sowie mehreren Ideallagen.
