Offre de Thèse : Full-field modeling of solid-solid phase transformations, recrystallization and grain growth- Application to Nickel base superalloys and titanium alloys

Postée le 19 jan.

Lieu : sophia antipolis  · Contrat : CDD · Rémunération : 27.7k€ €

Société : CEMEF

Le CEMEF, Centre de Mise en Forme des Matériaux (CEMEF) de Mines ParisTech basé à Sophia Antipolis, possède une expertise dans le domaine de la caractérisation et de la modélisation de la rupture en mise en forme et en service ainsi que des compétences en métallurgie et mise au point d’essais thermomécaniques.

Description du poste

This PhD will be firstly dedicated to the extension of existing numerical framework dedicated to the modeling of solid/solid phase
transformations where grain boundaries and subsequent driving
pressures are taken into account. Pre-existing developments [2,3]
in context of a level-set full-field formulation will be improved
and this mechanism will also be integrated to the ToRealMotion
front-tracking algorithms [1]. Ostwald ripening, adequate driving pressure leading to complex second phase particle shapes and
interaction mechanisms between evolving second phase particles
and grain interfaces will be investigated.
The developments will be tested/optimized thanks to experimental data concerning one nickel base superalloys and a titanium
The developments will be integrated in the DIGIMU®
