1. Martensitic Transformations in Steels : A 3D Phase-field Study
Abstract : Martensite is considered to be the backbone of the high strength of many commercial steels. Martensite is formed by a rapid diffusionless phase transformation, which has been the subject of extensive research studies for more than a century. READ MORE

2. Phase-field modeling of diffusion controlled phase transformations
Abstract : Diffusion controlled phase transformations are studied bymeans of the phase-field method. Morphological evolution ofdendrites, grains and Widmanst\"atten plates is modeled andsimulated.Growth of dendrites into highly supersaturated liquids ismodeled for binary alloy solidification.

3. Modeling of phase transformations and cyclic plasticity in pearlitic steels
Abstract : The low rolling resistance in railway transportation is a key factor for its high efficiency, but it comes at the price of very high contact pressure between the rail and wheel. Due to the high stresses and the large number of load cycles during railway operation, both the rail and the wheel can be susceptible to fatigue crack initiation and propagation. READ MORE

4. Phase Transformations in Solid Pharmaceutical Materials Studied by AFM, ESCA, DSC and SAXS
Abstract : Mixing excipients is a common way to produce pharmaceutical materials with suitable properties for drug formulation. An understanding of the basic mechanisms involved in the formation and transformation of the structures of solid state mixtures is crucial if one is to be able to produce materials with the desired properties in a reliable way.

5. Simulation of Phase Transformations and coarsening : Computational tools for alloy development
Abstract : The final properties of an alloy are highly interlaced with its microstructure. It is therefore essential to control the evolution of the microstructure of the material during the fabrication process. Nowadays, materials design involves an increasing part of computational design to complement the traditional experimental trial and error approach. READ MORE
