Mechanical Properties of Gas Metal Arc and Friction Stir AA6082-T6 Weldments
(Master thesis, 2013)The general purpose of the presents report is to determine the mechanical properties of AA6082-T6 subsequent to gas metal arc welding (GMAW) and friction stir welding (FSW). Hardness testing have been carried out for the ... -
Mechanical properties of lightweight aggregates
(Journal article; Peer reviewed, 2013)Lightweight aggregates (LWAs) were successfully produced both in a pilot-scale rotary kiln and in a laboratory chamber furnace. The mechanical properties of LWA were investigated in detail applying the European standard ... -
Mechanical stability of piezoelectric properties in ferroelectric perovskites
(Journal article; Peer reviewed, 2015)The influence of uniaxial compressive stress on the small signal direct piezoelectric coefficient of hard and soft Pb(Zr,Ti)O3 at the morphotropic phase boundary was investigated as a function of temperature from 25 °C to ... -
Mechanism behind the Inhibiting Effect of CO2 on the Oxidation of Al−Mg Alloys
(Journal article; Peer reviewed, 2018)Al–Mg alloys are known to suffer from problematic oxidation during melting, refining, and casting. The use of a CO2/air cover gas is known to minimize this oxidation; however, a mechanistic understanding of the beneficial ... -
Mechanism of the potential-triggered surface transformation of germanium in acidic medium studied by ATR-IR spectroscopy
(Journal article; Peer reviewed, 2016)In acidic solution, germanium surfaces undergo a transformation to hydrogen-terminated surfaces at sufficiently negative electrode potentials. Herein, we used in situ and operando attenuated total reflection infrared ... -
Mechanisms and Kinetics of Boron Removal from Silicon by Humidified Hydrogen
(Journal article; Peer reviewed, 2016)The removal of boron from silicon by top blowing of humidified hydrogen has been studied in the present work through experimental work, thermodynamic calculations, computational fluid dynamic modeling, and quantum chemistry ... -
Mechanisms and kinetics of liquid silicon oxidation
(Doktoravhandlinger ved NTNU, 1503-8181; 2013:145, Doctoral thesis, 2013)The formation of silica fume when liquid metal is in contact with air during refining of metallurgical grade silicon leads to a direct loss of silicon. Apart from this yield loss the associated fume may be harmful to the ... -
Mechanisms for texture in BaTiO3 thin films from aqueous chemical solution deposition
(Journal article; Peer reviewed, 2020)The prototype piezoelectric material BaTiO3 is widely used in e.g., capacitators. Chemical solution deposition (CSD) of BaTiO3 films is a simple and environmentally friendly processing route, but insight in the crystallization ... -
Mechanisms of graphite crucible degradation in contact with Si–Al melts at high temperatures and vacuum conditions
(Journal article; Peer reviewed, 2019)Graphite is a common refractory material for processing high purity silicon; however, it cannot be applied for holding Si–Al melts at high temperatures due to significant melt infiltration into the crucible. This research ... -
Mechanisms of inhibitor action - passivation and self-healing
(Chapter, 2020)In this chapter, we will briefly review the systematics of corrosion inhibitors and the classical mechanisms of action of corrosion inhibitors, the latter with an emphasis on inhibitors interacting with the material surface. ... -
