Simulation of Phase Transformation

The development and optimisation of new materials for high performance applications under enhanced and complex service conditions require new instruments for the treatment of transformations. They have to be based on fundamental principles in order to provide predictability. Empirical approaches cannot meet these requirements.

The computer simulation of phase transformation, based upon multi-component thermodnamics, offers an excellent tool for treating the kinetics of microstructure formation. This includes the mophological evolution during transitions, the prediction of precipitation sequences of stable and metastable phases and microstructural long term stability. Reliable thermodynamic data are available for a multitude of materials. Since data on the true thermodynamic driving forces are available, the kinetic data are reduced to the mobilities of the elements in the various structures. They are also available for many substances and phases.

At present there exist three approaches focusing on different aspects: (a) the sharp interface concept with local equilibrium at the moving boundary (DICTRA), (b) the phase field method with a diffuse interface allowing for a treatment of morphological evolutions like for instance dendritic solidification (MICRESS), (c) the meanfield treatment of multicomponent, multi-phase precipitation using the concept of maximum entropy production (Onsager's extremum principle), including finite interface mobilities and large deviations from local equilibrium (MatCalc).

It is the aim of this seminar
o to present these approaches in detail,
o to show their excellent predictive capability,
o to demonstrate how to work with the software.
This will be done interactively by particular case studies which include steels, Ni-base alloys, Al-alloys.

The seminar addresses materials engineers and scientists in research and development departments in industry and at Universities.

Veranstaltungsort:

The seminar takes place in the Seehotel Maria Laach situated 15 km west of Koblenz. It is overlooking the wide round of the largest Eifel maar, a volcanoe that has become extinct about 10000 years ago and that now forms a lovely lake surrounded by low mountains and isolated forests. Next to the Seehotel is the 900 year old monastry Maria Laach, a holy place for contemplation and mediation.
