1. Phase transformation and stability studies of the Zr-H system
Abstract : Zirconium alloys are widely used in the nuclear industry because of their high strength, good corrosion resistance and low neutron absorption cross-section. Zirconium has a strong affinity for hydrogen, however, and if hydrogen concentration builds up, the material will gradually degrade. READ MORE

2. Finite element simulation of transformation plasticity in martensitic transformation
Abstract : This study is concerned with the simulation of transformation plasticity in martensitic transformation. In the first paper the concept of a transformation plasticity strain is introduced from a phenomenological point of view. READ MORE

3. Transformation phenomena in a super duplex stainless steel
Abstract : Duplex stainless steels consist of about equal fractions offerrite and austenite and are attractive due to their highcorrosion resistance against pitting corrosion and stresscorrosion cracking. The pitting corrosion resistance can bedescribed by the PREN value which is defined asPREN=%Cr+3.3*%Mo+16*%N. READ MORE

4. In-situ phase studies of the Zr-H system
Abstract : Zirconium alloys are widely used in the nuclear industry because of their high strength, good corrosion resistance and low neutron absorption cross-section. However, zirconium has strong affinity for hydrogen, which may lead to hydrogen concentration build-up over time during a corrosion reaction when exposed to water. READ MORE

5. 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.
