Effect of small concentrations of gallium and lead on anodic activation of aluminium in chloride solution
(Journal article; Peer reviewed, 2018)The presents objective is to investigate the combined effect of alloyed Pb and Ga on surface segregation by heat treatment and ensuing anodic activation of aluminium in chloride solution. Model alloys containing Pb and Ga, ... -
Effect of soft Bi particles on grain refinement during severe plastic deformation
(Journal article; Peer reviewed, 2017)Two aluminum alloys, Al–8Zn and Al–6Bi–8Zn were subjected to equal channel angular pressing (ECAP) up to 5 passes at room temperature. The microstructural evolution and the grain refinement behavior of these alloys were ... -
Effect of Solution Annealing on Plasma Weld Deposited Ti-6Al-4V Characterized by In-Situ Tensile Testing Combined With EBSD
(Master thesis, 2014)This work is based on the work done by Mathisen et al. [1], which considers the mechanical properties of the components produced by Norsk Titanium (NTi). NTi produces Ti-6Al-4V (grade 5 titanium) components by additive ... -
Effect of Sulfide Inclusions in Austenitic Stainless Steel on the Initiation of Pitting in Base Metal and Heat Affected Zone after Welding
(Master thesis, 2012)The predominant site for the initiation of pitting on austenitic stainless steel has been shown to be sulfide inclusions and notably the manganese types of sulfides. Dissolution of inclusions has been observed and suggested ... -
