21. Defect Formation during Solidification in Grey Iron Castings
Sammanfattning : The presence of defects is of major concern in the production of grey iron castings. Some defects are merely an aesthetic problem while others can be detrimental for the performance of the component. Among the several possible defects, shrinkage porosity is one of the more challenging to understand and avoid. LÄS MER
22. Reaching Kinetic Selectivities : In Pursuing Novel Ternary Oxide Coatings, and Beyond
Sammanfattning : Kinetically driven synthesis pathways have the potential to allow new ways to develop materials and phases with much-improved properties. This particularly concerns metastable and multicomponent phases that require a selective kinetic targeting during the synthesis to circumvent the formation of thermodynamically stable products.

23. Multiscale modeling of dynamic recrystallization
Sammanfattning : During thermomechanical processing of metals, changes occur in the microstructure of the material which affect its macroscopic properties. By understanding these transformations in the microstructure, it becomes possible to design the processes in a way which yields the desired properties in the finished product. LÄS MER
24. Toward Anti-icing and De-icing Surfaces : Effects of Surface Topography and Temperature
Sammanfattning : Icing severely affects society, especially in the Nordic countries. Iceaccumulation can result in critical performance problems and safetyconcerns for instance in road, air and sea transportation, transmissionlines, marine and offshore structures, wind turbines and heat exchangers.
