Characterization and Mechanical Testing of Co-Extruded Rods with an AA6082 Core and Rapidly Solidified AA7090/AA7090-Sc Sleeve
Bjerkestrand, Vegard Jørgenvåg (Master thesis, 2018)The development and implementation of materials having a combination of mechanical properties, e.g. high strength and high ductility, have been of interest within the material science community for decades. In the growing ... -
Cu Interlayer-Induced High-Strength Laser-Welded AISI 304 Steel-Niobium Joint
Shi, Mingxiao; Li, Yanjun; Ma, Xiang (Peer reviewed; Journal article, 2019)Joining niobium to austenitic stainless steel is necessary for the fabrication of particle accelerators. However, the brittle iron-niobium intermetallics formed in the joint significantly reduce the joint strength. Copper ... -
Laser welding of niobium to AISI 304 steel using a copper interlayer
Zhao, Jian; Shi, Mingxiao; Li, Yanjun; Ma, Xiang; Fang, Zhenxing; Yan, Hua (Peer reviewed; Journal article, 2020)Cu interlayers with thicknesses of 1, 1.5, and 2 mm were used to join niobium and AISI 304 steel. Fractures occurred in the weld, the Nb base metal, and the unmelted Cu interlayer when the Cu interlayer thickness was 1, ... -
Magnesiothermic Reduction of Silica: A Machine Learning Study
Tang, Kai; Rasouli, Azam; Safarian, Jafar; Ma, Xiang; Tranell, Maria Gabriella (Peer reviewed; Journal article, 2023)Fundamental studies have been carried out experimentally and theoretically on the magnesiothermic reduction of silica with different Mg/SiO2 molar ratios (1–4) in the temperature range of 1073 to 1373 K with different ... -
Removal of Phosphorus in Metallurgical Silicon by Rare Earth Elements
Tang, Kai; Løvvik, Ole Martin; Safarian-Dastjerdi, Jafar; Ma, Xiang; Tangstad, Merete (Journal article; Peer reviewed, 2014)Removal of phosphorus in metallurgical silicon is one of the crucial steps for the production of solar grade Si feedstock. The possibility of doping rare earth elements for phosphorus removal has in this work been studied ...
