• Control of conductivity and electric field induced strain in bulk Bi0.5K0.5TiO3-BiFeO3 ceramics 

      Morozov, Maxim; Einarsrud, Mari-Ann; Grande, Tor (Journal article; Peer reviewed, 2014)
      High electrical conductivity is one of the main obstacles for advances of bulk BiFeO3 ceramics in piezoelectric applications. Here, we demonstrate that the electrical conductivity of BiFeO3 can be lowered by compositional ...
    • Formation of incoherent deformation twin boundaries in a coarse-grained Al-7Mg alloy 

      Jin, Shenbao; Zhang, Kai; Bjørge, Ruben; Tao, NR; Marthinsen, Knut; Lu, K; Li, Yanjun (Journal article; Peer reviewed, 2015)
      Deformation twinning has rarely been observed in coarse grained Al and its alloys except under some extreme conditions such as ultrahigh deformation strain or strain rates. Here, we report that a significant amount of Σ3 ...
    • Polarization and strain response in Bi0.5K0.5TiO3-BiFeO3 ceramics 

      Morozov, Maxim; Einarsrud, Mari-Ann; Grande, Tor (Journal article; Peer reviewed, 2012)
      Highly dense and phase-pure ferroelectric ceramics in the (1-x)Bi0.5K0.5TiO3–xBiFeO3 system have been prepared and examined in a wide range of composition (0.1 ≤ x ≤ 0.9). The dielectric and electromechanical properties ...
