Research areas

The Chair’s activities revolves around four main research objectives :

  1. Understand the influence of high temperature deformation parameters and develop material models to simulate conditions encountered in industrial practice.
  3. Identify the micromechanisms responsible for the evolution of the mechanical properties of formed parts under industrial working conditions.
  5. Optimize current forming processes and develop new alloys and new thermomechanical processes, using high temperature deformation testing, with a view to mapping microstructure evolution of the investigated materials:
    • Determine the phase transformation kinetics; investigate static, dynamic, and metadynamic recrystallization phenomena; investigate precipitation kinetics of secondary phases before and after phase transformation.
    • Study the influence of the strain path and crystalline texture on microstructure behaviour during forming.
  6. Develop reliable methods allowing the realistic prediction of mechanical behaviour during the various stages of forming:
    • Identification of micromechanisms responsible for the presence of microstructural heterogeneities, which lead to the deterioration of mechanical properties.
    • Development of simulation tools, based on thermodynamics and kinetics studies, in order to predict the occurrence of microstructural heterogeneities, as a function of process parameters.
    • Development of constitutive equations taking into account microstructure evolution to predict and control the macroscopic behaviour.
    • Design and application of simulation models for forging and heat treatment processes, based on the actual behaviour of the material.
