Vapour Pressure of Bi above Bi-Ti Alloys by Transpiration Method
(Master thesis, 2017)Titanium is an attractive metal with wide-ranging applications due to its properties. Titanium is one of the most corrosion resistant metals with the highest strength-to-weight ratio. The only industrial production route ... -
Varmtorsjonstesting av 3xxx-legeringer
(Master thesis, 2014)Styrkeeffekten av dispergerte partikler har blitt utforsket for en 3xxx-legering ved varmtorsjons-testing. Legeringens komposisjon var: 0,97wt.% Mn, 0,5wt.% Fe, 0,15wt.% Si og 0,05wt.% annet. Det er gjort fire forskjellige ... -
Verification of Experimentally Determined Permeability and Form Coefficients of Al2O3 Ceramic Foam Filters (CFF) at High and Low Flow Velocity Using a CFD Model
(Journal article, 2018)Filtration using Ceramic Foam Filters (CFFs) is a method widely used to separate inclusions from molten aluminium. In the present work, the specific permeability and form drag coefficients of nominal 50 mm thick commercial ... -
Very sharp diffraction peak in nonglass-forming liquid with the formation of distorted tetraclusters
(Peer reviewed; Journal article, 2020)Understanding the liquid structure provides information that is crucial to uncovering the nature of the glass-liquid transition. We apply an aerodynamic levitation technique and high-energy X-rays to liquid (l)-Er2O3 to ... -
