11. Elastic Properties of Iron Alloys from First-Principles Theory
Sammanfattning : Accurate description of materials requires the most advanced atomic-scale techniques from both experimental and theoretical areas. In spite of numerous available techniques, however, the experimental study of the atomic-scale properties and phenomena even in simple solids is rather difficult. LÄS MER
12. Structure and mechanical properties of polycrystalline iron-silicon alloys
Sammanfattning : .... LÄS MER
13. 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
14. On improvement of cast iron brake discs for heavy vehicles
Sammanfattning : Disc brakes are commonly used in motorcycles, passenger cars, commercial vehicles, heavy-duty vehicles, passenger trains and landing gears of airplanes. Depending on the application, a wide variety of brake discs have been developed, with a multitude of designs, geometries and materials. LÄS MER
15. Effects of disorder in metallic systems from First-Principles calculations
Sammanfattning : In this thesis, quantum-mechanical calculations within density-functional theory on metallic systems are presented. The overarching goal has been to investigate effects of disorder. In particular, one of the properties investigated is the bindingenergy shifts for core electrons in binary alloys using different theoretical methods. LÄS MER
