Viewpoint on the Formation and Evolution of Annealing Twins During Thermomechanical Processing of FCC Metals and Alloys
Nathalie Bozzolo,Marc Bernacki +1 more
TL;DR: The question of the formation mechanism of annealing twins in face-centered cubic metals and alloys, which is still not resolved in spite of the fact that the existence of these defects is known for long, is addressed in this article.

Energetic upscaling strategy for grain growth. I: Fast mesoscopic model based on dissipation.
TL;DR: In this article, a fast mesoscopic model based on Voronoi-Laguerre tessellations is proposed to model anisotropic grain growth at large scale without losing detailed grains statistics.

TL;DR: In this paper, it is shown that neglecting torque effects in full-field formulations can have a significant effect on the overall rate of grain growth, the shape of grains and grain boundaries as well as their local kinetics.

Probabilistic and deterministic full field approaches to simulate recrystallization in ODS steels
Flore Villaret,Flore Villaret,B. Hary,Y. de Carlan,Thierry Baudin,Roland E. Logé,Ludovic Maire,Marc Bernacki +7 more
TL;DR: In this article, two well-known full field methodologies dedicated to recrystallization modeling, the level-set and the Monte Carlo methods, are applied, discussed and compared to experimental data in their ability to describe properly recrystization for ODS steels.
