Atomic configurations and diffusion mechanisms near the asymmetric grain boundaries in tetragonal CuAu I alloy with <100 > and <001 > tilt axes

  • Published:
Russian Physics Journal Aims and scope

The molecular dynamics method is used to investigate an atomic configuration in the structure of asymmetric tilted grain boundaries for the ordered CuAu I alloy with FCT symmetry and L10 structure. Investigations are performed for three misorientation angles: 7, 16, and 22° and grain boundaries with <100 > and <001 > tilt axes. The distinctive features of the structural grain boundary reorganization and diffusion mechanisms are elucidated at different temperatures.
