Removal of Aluminium Carbide from Liquid Aluminium
(Master thesis, 2018)Aluminium carbide (Al4C3) inclusions are a common type of impurity found in aluminium alloys. Currently aluminium carbide cannot be efficiently removed due to its small particle size and wetting properties. The small carbide ... -
Carbon segregation at Σ3 {112} grain boundaries in silicon
(Journal article; Peer reviewed, 2018)First-principles calculations were carried out to systematically investigate the carbon segregation along Σ3 {1 1 2} grain boundaries (GBs) in silicon. The energetically favorable segregation sites and corresponding ... -
Domain-Pattern Transfer across an Artificial Magnetoelectric Interface
(Journal article; Peer reviewed, 2018)Magnetoelectric interfaces provide efficient pathways for manipulating the magnetic order with low-power-consuming electric fields. A prime example of this is the voltage-controlled domain-pattern transfer from a multiferroic ... -
Bimetallic Nano Electrocatalyst for HER in Alkaline Polymer Electrolysis
(Journal article; Peer reviewed, 2018)Ni and alloys of Ni (with Fe, Co, Mo) still represent the most suitable electrodes for HER in alkaline media. Bimetallic nanoparticles of NiFe and NiCo were fabricated by co-precipitation and thermal reduction by oleylamine. ... -
The multiple roles of an organic corrosion inhibitor on copper investigated by a combination of electrochemistry-coupled optical in situ spectroscopies
(Journal article; Peer reviewed, 2018)The interaction of the organic corrosion inhibitor 2-mercaptobenzothiazole (MBT) with copper in alkaline solution was investigated by in situ infrared (IR) and Raman spectroscopy, and in situ spectroscopic ellipsometry, ... -
Formation of Copper–Neodymium Intermetallic Compounds by Carbothermic Reduction of Neodymium Oxide in the Presence of Copper
(Journal article; Peer reviewed, 2018)Carbothermic reduction of neodymium(III) oxide (Nd2O3) was performed by arc melting and in a graphite resistance furnace, using copper as a solvent metal. Successful carbothermic reduction was evident by formation of ... -
Direct Method for Producing Scandium Metal and Scandium-Aluminium Intermetallic Compounds from the Oxides
(Journal article; Peer reviewed, 2018)The electrochemical de-oxidation process, also called FFC-Cambridge process, has been proposed previously to produce reactive metals and their alloys through reduction of their metal oxides. The process works by introducing ... -
Mechanical properties of bainitic and martensitic high strength steels in the hardened and untempered state
(Master thesis, 2018)The objective of the research project named RoHard, is to increase the understanding of the interaction between the quality of the incoming materials, the hardening process and the resulting mechanical properties of the ... -
In-situ determination of thickness and electrochemical properties of barrier oxide film on impure aluminium in aqueous solution
(Journal article; Peer reviewed, 2018)Lead is present as a trace element (ppm level) in nearly all commercial aluminium alloys. The objective of this work is to investigate the changes incurred by the presence of a small amount (20 ppm) of alloyed Pb and heat ... -
Orientation relationship between b-Si3N4 and Si in multicrystalline silicon ingots for PV applications
(Journal article; Peer reviewed, 2018)β-Si3N4 particles are thought to be nucleation sites for silicon in multicrystalline silicon (mc-Si) ingots for PV applications. The orientation relationship (OR) between Si and β-Si3N4 has been investigated by transmission ... -
Atomic structures of precipitates in Al–Mg–Si alloys with small additions of other elements
(Journal article; Peer reviewed, 2018)In Al–Mg–Si alloys, additions of only a few weight percent of Mg and Si enable formation of hardening precipitates during heat treatment. The precipitation is complex and is influenced by chemical compositions and ... -
Through thickness variations of deformation texture in round profile extrusions of 6063-type aluminium alloy: Experiments, FEM and crystal plasticity modelling
(Journal article; Peer reviewed, 2018)The deformation texture and its through-thickness heterogeneity for an extruded round profile are experimentally measured by the electron back-scatter diffraction technique (EBSD), and numerically modelled by coupling FEM ... -
