1. Precipitate growth and coarsening in creep resistant chromium steels
Sammanfattning : .... LÄS MER
2. Multicomponent diffusional reactions in tool steels : Experiment and Theory
Sammanfattning : Many phenomena determining the microstructure of a tool steel and consequently the properties of the material, are governed by multicomponent diffusion. The diffusion driven reactions that take place during, for example, tempering of a hot-work tool steel or when the microstructure develops during hot isostatic pressing of cold-work tool steel, are dependent on the types and amounts of alloying elements.

3. Aspects of Structural Evolution in Cemented Carbide – Carbide Size, Shape and Stability
Sammanfattning : Cemented carbide is a composite material used in applications like cutting tools and rock drilling inserts. The material commonly consists of WC grains embedded in a Co-rich binder phase and the material properties strongly depend on the WC grain size. LÄS MER
4. Aspects of microstructural evolution in chromium steels in high temperature applications
Sammanfattning : In this thesis 9-12 % Cr steels, used for high-temperaturecomponents in fossil-fired power plants are considered. Thecreep strength of thees steels depend on their microstructurethat consists of a matrix of tempered lath martensite withdensely distributed precipitates. LÄS MER
5. The role of primary austenite morphology in cast iron
Sammanfattning : Automotive industry products portfolio includes a wide variety of complex-shaped cast iron products, such as truck engine components. Urged by strict environmental regulations on emissions, these components constantly need to combine higher demands on performance with lighter designs. LÄS MER
