16. Quantitative equilibrium calculations on systems with relevance to copper smelting and converting
Sammanfattning : The present thesis gives a summary of results obtained through theoretical and experimental studies of systems with relevance to copper smelting and converting.Many chemical elements are involved in the copper production processes and a detailed experimental study would be very time- consuming and expensive.

17. Profitability = f(G) : Computational Thermodynamics, Materials Design and Process Optimization
Sammanfattning : The thesis starts by giving a motivation to materials modeling as a way to increase profitability but also a possibility decrease the environmental impact. Fundamental concepts of relevance for this work are introduced, this include the materials genome, ICME and of course the CALPHAD method. LÄS MER
18. Equilibrium aspects of Cr-alloyed cemented carbides
Sammanfattning : In view of the extensive use of Cr as a grain growth inhibitor in WC-Co cemented carbides this thesis comprises a combined experimental and ab initio study of a number of critical issues pertaining to phase equilibria of the subsystems to the W-Co-Cr-C system.To be able to predict which of the stable Cr-carbides forms above the solubility limits of Cr and C in the fcc phase the respective solubility of Co in Cr23C6, Cr7C3 and Cr3C2 are investigated experimentally.

19. Experimental and theoretical study of carbides in the Co-Cr-C system : Structure, alloying and stability
Sammanfattning : The research presented in this thesis explores the structure, alloying and stability of the carbides in the Co-Cr-C system by using the CALPHAD approach supported by experimental measurements and ab initio calculations.WC-Co based cemented carbide materials consist of hard WC grains and a ductile Co-based binder.

20. On the optimal use of industrial-generated biomass residues for polygeneration
Sammanfattning : Increasing energy demand as well as climate change concerns call for an analysis and optimization of energy services. Efficient use of energy resources, mitigation of environmental effects and supply an increasing demand are just some of the issues that are relevant nowadays in the energy system. LÄS MER
