3D level set modeling of static recrystallization considering stored energy fields
Benjamin Scholtes,Romain Boulais-Sinou,Amico Settefrati,Daniel Pino Muñoz,Isabelle Poitrault,Aurore Montouchet,Nathalie Bozzolo,Marc Bernacki +7 more
TL;DR: A new efficient implementation of the static recrystallization (SRX) model which aims to overcome this limitation by taking full advantage of recent numerical developments (Shakoor et al., 2015; Scholtes et al, 2015).
Journal ArticleDOI
Modeling of heat transfer and turbulent flows inside industrial furnaces
Elie Hachem,Ghina Jannoun,Jérémy Veysset,Marc Henri,Romuald Pierrot,Isabelle Poitrault,Elisabeth Massoni,Thierry Coupez +7 more
TL;DR: The method demonstrates the capability of the model to simulate an unsteady heat transfer flow of natural convection, conduction and radiation in a complex 3D industrial furnace with the presence of six conducting steel solids.
Journal ArticleDOI

Todt,Olivier Minster,Wim H. Sillekens +26 more
TL;DR: In this article, a columnar-to-equiaxed transition in solidification processing (CETC) was detected only for refined alloys, either as a sharp CET in case of a sudden increase in the solidification velocity or as a progressive CET in the case of continuous decrease of the temperature gradient.
Journal ArticleDOI
Analysis of columnar-to-equiaxed transition experiment in lab scale steel casting by a multiphase model
S. Sachi,Miha Založnik,Hervé Combeau,Ch.-A. Gandin,Marvin Gennesson,Joëlle Demurger,M. Stoltz,Isabelle Poitrault +7 more
TL;DR: In this paper, the columnar to equiaxed transtion (CET) is a microstructural transition which is strictly controlled as it affects the mechanical properties of the final product along with the macrosegregation patterns.
