6. Phase diagram evaluations and applications in light metal alloys
Sammanfattning : A thermodynamic database for light alloys have been assessedusing the CALPHAD method. The database contains a newevaluation of aluminium rich alloys containing Fe, Mn and Si,and it may be used also for alloys containing small amounts ofMg. LÄS MER
7. Mechanical Properties of Transition Metal Alloys from First-PrinciplesTheory
Sammanfattning : The aim of the thesis is to investigate the alloying and temperature effects on the mechanical properties of body-centered cubic (bcc) random alloys. We employ the all-electron exact muffin-tin orbitals method in combination with the coherent-potential approximation. LÄS MER
8. Ab initio prediction of the mechanical properties of alloys
Sammanfattning : At the time of the 50th anniversary of the Kohn-Sham method, ab initio calculations based on density functional theory have formed an accurate, efficient, and reliable method to work on the properties of engineering materials. In this thesis, we use the exact muffin-tin orbitals method combined with the coherent-potential approximation to study the mechanical properties of high-technology materials. LÄS MER
9. Mechanical Properties of Transition Metal Alloys from First-Principles Theory
Sammanfattning : The aim of the thesis is to investigate the alloying effect on the mechanical properties of random alloys using the all-electron exact muffin-tin orbitals methodin combination with the coherent-potential approximation. The second-order elastic constants describe the mechanical properties of materials in the small deformation region, where the stress-strain relations arelinear. LÄS MER
10. On deoxidation practice and grain size of austenitic manganese steel
Sammanfattning : The exceptional wear resistance and work hardenability, place Hadfield steel as one of themost important materials for manufacturing cast components used in the mining, crashing,drilling, and excavation industries. In all metallic alloys used for component casting, themechanical properties are highly influenced by the microstructure of the material. LÄS MER
