3. Precipitation during Tempering of Martensite in Fe-Cr-C alloys
University essay from KTH/MaterialvetenskapAbstract : The martensite structure is the most important microstructure in tool steel due to its high hardness. However, a lack of ductility is the major drawback. In order to improve the ductility and still maintaining a suitable hardness a tempering process is needed. READ MORE

4. First-Principles calculations of Core-Level shifts in random metallic alloys: The Transition State Approach
University essay from Institutionen för fysik, kemi och biologiAbstract : The overall aim of this thesis is to compare different methods for calculation of Core-Level shifts in metallic alloys. The methods compared are the Initial State model, the Complete screening and the Transition state model. Core-level shifts can give information of chemical bonding and about the electronic structure in solids. READ MORE

5. Ab-initio study of disorder broadening of core photoemission spectra in random metallic alloys
University essay from Institutionen för fysik, kemi och biologiAbstract : Ab-initio results of the core-level shift and the distribution about the average for the 3d5/2 electrons of Ag, Pd and 2p3/2 of Cu are presented for the face-centered-cubic AgPd and CuPd random alloys. The complete screening model, which includes both initial and final states effects in the same scheme, has been used in the investigations. READ MORE
