3-years research study at CEMEF.
The Centre for Material Forming (CEMEF) is one of the research laboratories of MINES ParisTech (top executive French engineering school).
CEMEF studies the materials processings in all their aspects: physics, chemical physics, thermal and mechanical analysis and numerical modelling. Researches are on a large range of materials: metals, synthetic and bio polymers, food stuff, composites and nanocomposites, glass, ceramics…
Subject: The control of solidification structures is a main issue for casting industries. Properties are indeed directly linked to microstructures. This is particularly true for metallic alloys with high added value such as nickel base superalloys, steels for automotive applications, alloys for nuclear power plants... Numerical simulation of processes plays a key role in this field. The Centre for Materials Forming (www.cemef.mines-paristech.fr) and the company TRANSVALOR (www.transvalor.com) develop the commercial software THERCAST used by the industrial partners of the present project.
The Centre for Materials Forming is a main actor in this field, in which considerable progress have been achieved over the last years. An example of simulation is given below, showing the coupling of heat and mass transfers solved by a finite element method with the development of a grain structure model predicted with a cellular automaton method. Multiscale modelling is thus achieved, the microscale of the dendritic structure to the macroscale of the cast part......
