      Khalid, Muhammad Zeeshan; Zubair, Muhammad; Ali, Majid (Journal article; Peer reviewed, 2019)
      Two phase Stefan problem was solved using analytical method in cylindrical domain. To solve governing equations Eigen conditions were formulated by using separation of variable technique. Eigenvalues of the eigencondition ...

    • Atomistic modelling of Fe-Al and α-AlFeSi intermetallic compound interfaces 

      Khalid, Muhammad Zeeshan (Doctoral theses at NTNU;2020:86, Doctoral thesis, 2020)
      The joining of aluminum and steel has been considered an efficient solution for building light-weight technology, particularly in the automotive, aerospace and shipbuilding industries. It is an immense challenge to join ...

    • First-principles study of tensile and shear strength of an Fe2Al5//Fe interface 

      Khalid, Muhammad Zeeshan; Friis, Jesper; Ninive, Per Harald; Marthinsen, Knut; Ringdalen, Inga Gudem; Strandlie, Are (Peer reviewed; Journal article, 2021)
      The interfacial strengths of a low misfit Fe2Al5//Fe interface structure found at aluminum-steel joints has been studied using density functional theory. An interface between Fe and Fe2Al5 was selected based on a criteria ...
