Directed laser deposition of super duplex stainless steel: Microstructure, texture evolution, and mechanical properties
Sayyar, Navid; Hansen, Vidar Folke; Tucho, Wakshum Mekonnen; Minde, Mona Wetrhus (Peer reviewed; Journal article, 2023-04)Microstructure and texture evolution of directed-laser deposited super-duplex stainless-steel, in the as-received block, were characterized using light and electron microscopies and electron backscattered diffraction. ... -
EBSD and TEM study of DMD manufactured cp-TI (grade 2)
Berg, Alexander (Masteroppgave/UIS-TN-IMBM/2018;, Master thesis, 2018-06-29)Two components, 3D printed by Norsk Titanium components, through a direct metal deposition plasma transferred arc. An additive layer manufacturing technique. One made of a single wire layer thin sample, and one made of two ... -
Electron channeling studies of atom site preference and distribution in doped Mg2Si1-xSnx thermoelectrics
Delimitis, Andreas; Kyratsi, Theodora; Hansen, Vidar Folke (Peer reviewed; Journal article, 2022)The electron channeling effect, i.e., the dependence of the characteristic x-ray emission on the crystallographic direction of the incoming beam in an analytical transmission electron microscope was employed to elucidate ... -
Mechanical and microstructural assessment of a novel 3D-printed AlSi10Mg- Ti6Al4V alloy using Direct Laser Deposition
Hidle, Stian Runestad (Master thesis, 2023)A novel AlSi10Mg-Ti6Al4V alloy fabricated through DLD was investigated. The novel alloy consists of 92 wt.% AlSi10Mg and 8 wt.% Ti6Al4V. The alloy was found to have very weak mechanical properties, but it was very apparent ... -
Microstructure and Mechanical Properties of SLM Printed Super Duplex Stainless Steel (EN 1.4410)
Yadav, Pravesh Kumar (Master thesis, 2021)The purpose of this study is to investigate the microstructural and mechanical characterization of super duplex stainless steel of grade EN 1.4410 / AISI SAF 2507 manufactured by selective laser melting (SLM). The findings ... -
Microstructure and mechanical tests of a weld on a TIG welded UNS S31803 duplex stainless steel pipe
Heggholmen, Silje Helen (Master thesis, 2023)University of Stavanger was given a pipe consisting of two parts of the duplex stainless steel grade UNS S31803, which had been welded together using TIG welding. The thesis is about examining the weld that goes around the ... -
Studies of Post-Fabrication Heat Treatment of L-PBF-Inconel 718: Effects of Hold Time on Microstructure, Annealing Twins, and Hardness
Tucho, Wakshum Mekonnen; Hansen, Vidar Folke (Peer reviewed; Journal article, 2021-02)The widely adopted temperature for solid solution heat treatment (ST) for the conventionally fabricated Inconel 718 is 1100 °C for a hold time of 1 h or less. This ST scheme is, however, not enough to dissolve Laves and ...
