4. 13. Thermodynamic Investigation of Co-Cr Alloys

   Författare :Thérèse Sterneland; KTH; []
   Nyckelord :Cobalt; chromium; experimental thermodynamics; solid state galvanic cell technique; differential scanning calorimetric technique DSC ; CALPHAD-technique; Thermo-Calc; phase diagram; experimental data;

   Sammanfattning : In a collaborative effort between the Divison of Metallurgyand the Divison of Computational Thermodynamics, RoyalInstitute of Technology (KTH), Stockholm, Sweden, experimentalinvestigations have been carried out in the binary Co-Crsystem. The experimental strategy has been to measure thethermodynamic activities of Cr by the solid oxide electrolytegalvanic cell technique, as well as to measure the molar heatcapacities of the alloys, as function of temperature, by theDSC technique.

5. 14. Alloys in Contact with Molten Salts for Thermal Storage Applications

   Författare :Esraa Hamdy Mohamedin; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Phase transition; Molten salts; High-temperature corrosion; Alumina-forming alloys; Carburisation; Thermal energy storage TES ; Laves phase; Concentrated solar power CSP ;

   Sammanfattning : The combination of a concentrated solar power (CSP) plant and a thermal energy storage (TES) system is a promising technology for power generation, in that it overcomes the challenges commonly faced by renewable energy systems, such as intermittency, dispatchability, and the gap between the energy supply and energy demand. The third generation (Gen3) CSP plants are designed to increase plant efficiency by using supercritical carbon dioxide (sCO2) instead of steam for the Brayton cycle gas turbines, requiring a minimum operating temperature of 750°C for the TES materials.

7. 15. Simulation of diffusional processes in alloys : techniques and applications

   Författare :Henrik Strandlund; John Ågren; John Morral; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diffusion; Kirkendall effect; Phase transformations; Random walk; Solute drag; Interfacial mobility; Other materials science; Övrig teknisk materialvetenskap;

   Sammanfattning : This thesis concerns computer simulation of diffusional processes in alloys. The main focus is on the development of simulation techniques for diffusion in single-phase domains, but also diffusion controlled phase-transformations and interfacial processes are discussed. LÄS MER
