Filtration of Aluminium Melts using Ceramic Foam Filters (CFF) and Electromagnetic Field
(Master thesis, 2011)AbstractThe objective of the experimental trials was to investigate the influence of the electromagnetic force generated by an AC powered solenoid on ceramic foam filters (CFF) of different filter grades (30, 50 and 80 ... -
Filtration of Aluminium-Experiments, Wetting,and Modelling
(Doktoravhandlinger ved NTNU, 1503-8181; 2011:, Doctoral thesis, 2011)The present work deals with the inclusion removal mechanism in aluminium filtration and the use of alternative filter materials. Four routes are investigated. First, an overview of previous research on filtration knowledge ... -
Finite element analysis of strain distribution in ZK60 Mg alloy during cyclic extrusion and compression
(Journal article; Peer reviewed, 2012)Finite element method was used to study the strain distribution in ZK60 Mg alloy during multi-pass cyclic extrusion and compression (CEC). In order to optimize the CEC processing, the effects of friction condition and die ... -
Finite temperature ab initio simulations of the lattice thermal conductivity of XNiBi, X=(Sc, Y, La), based half-Heuslers
(Master thesis, 2017)Over the past few years, the half-Heusler materials have attracted attention for their potential within thermoelectric applications. This is mainly due to the flexibility of half-Heusler crystal structure. The half-Heuslers ... -
Finite-size effects of Kirkwood–Buff integrals from molecular simulations
(Journal article; Peer reviewed, 2017)The modelling of thermodynamic properties of liquids from local density fluctuations is relevant to many chemical and biological processes. The Kirkwood–Buff (KB) theory connects the microscopic structure of isotropic ... -
First principles study of epitaxial strain induced phenomena and chemical expansion in perovskite oxides
(Doctoral theses at NTNU;2018:285, Doctoral thesis, 2018)The many exotic properties found in complex oxides have great potential for device applications. Complex oxides within the perovskite structure are particularly attractive, as they display a large diversity of chemical ... -
First-Principles Calculations of Oxygen Vacancy Formation in Epitaxially Strained La1-xCaxMnO3
(Master thesis, 2016)Using epitaxial strain as a degree of freedom is a promising way to tailor the properties in thin films of transition metal oxides. Since the ground state of such materials tend to have many competing low-energy states ... -
