    • Comparative kinetics study of different iron-containing pellets with hydrogen at isothermal conditions 

      Kar, Manish Kumar; Zhu, Mengyi; Safarian, Jafar (Peer reviewed; Journal article, 2023)
      Using hydrogen to produce iron is a promising way for the steel industry to achieve the goal of carbon neutrality. The reducibility of iron-bearing oxides by hydrogen significantly impacts the productivity and energy ...

    • C–O–H2 ternary diagram for evaluation of carbon activity in CH4-containing gas mixtures 

      Ribeiro, T.R.; Ferreira Neto, Neto; Takano, C.; Poço, J.G.R.; Kolbeinsen, Leiv; Ringdalen, Eli (Peer reviewed; Journal article, 2021)
      The C–O–H2 ternary diagram is presented to characterize the carbon activity in equilibrium with gas mixtures containing CH4, CO, CO2, H2O, and H2 at different temperatures and pressures. The three reactions for carbon ...

    • Effect of scandium on grain refinement mechanism and mechanical properties of Al–7Si–0.6 Mg alloy at different cooling rates 

      Mao, Hongkui; Lian, Peng; Wei, Qi; Wang, Yu; Xu, Hong; Li, Yanjun (Peer reviewed; Journal article, 2023)
      The effects of scandium (Sc) additions on the solidification microstructure and mechanical properties of Al–7Si–0.6Mg-0.25Ti alloy at different cooling rates have been systematically studied by thermal analysis and detailed ...

    • The evolution of precipitates in an Al–Zn–Mg alloy 

      Thronsen, Elisabeth; Shah, Sohail; Hatzoglou, Constantinos; Marioara, Calin Daniel; Wenner, Sigurd; Andersen, Sigmund Jarle; Holmedal, Bjørn; Holmestad, Randi (Peer reviewed; Journal article, 2023)
      The precipitation sequence in Al–Zn–Mg alloys has been subject to many revisions over the years as more structural details of the early-stage Guinier-Preston (GP) zones and precipitates have been uncovered. To further ...

    • Influence of natural aging and ramping before artificial aging on the microstructure of two different 6xxx alloys 

      Hell, Christoph Martin; Søreide, Hanne-Sofie Marie Scisly; Bjørge, Ruben; Marioara, Calin Daniel; Li, Yanjun; Holmestad, Randi (Peer reviewed; Journal article, 2022)
      In this study the effect of a ramp up to artificial aging (AA) temperature in combination with natural aging (NA) was analyzed for two different industrial aluminium alloys. The alloys differ in their Mg/Si ratio as well ...

    • A machine learning enabled ultra-fine grain design strategy of Mg–Mn-based alloys 

      Mi, Xiaoxi; Jing, Xuerui; Wang, Hailian; Xu, Jianbin; She, Jia; Tang, Aitao; Holmedal, Bjørn; Pan, Fusheng (Peer reviewed; Journal article, 2023)
      Grain size is the critical characteristic of ultra-fine grain Magnesium (Mg), which is a concrete representation of the whole heat deformation procedure. In this paper, a design strategy was proposed to quantitatively ...

    • Preparation of ZrB<inf>2</inf>coatings by electrophoretic deposition in NaCl-KCl-AlCl<inf>3</inf>molten salts 

      Ge, Chuntao; Kou, Qian; Pang, Jie; Zhang, Jun; Jin, Weiliang; Zhu, Hongmin; Haarberg, Geir Martin; Xiao, Saijun (Peer reviewed; Journal article, 2022)
      Fabrication of transition metal diboride coatings via electrophoretic deposition in molten salts has been recently proposed, however, the influence of the process parameters on the coating has not yet been studied extensively. ...

    • Titanium Carbide Coating on Graphene Nanoplatelets 

      Khan, Mahmood; Ahmad, Salman; Zaidi, Sarim; Wadood, Abdul; Subhani, Tayyab; Akhtar, Shahid; Husain, Syed Wilayat; Aune, Ragnhild Elizabeth (Peer reviewed; Journal article, 2020)
      Titanium carbide was formed on graphene nanoplatelets (GNPs) using potassium hexa-fluorotitanate (K2TiF6) salt in the presence of pure aluminium. K2TiF6 - GNPs mixture with titanium to carbon ratio of 5:1 was heated at a ...
