Critical analysis of driving force for pure-step migration by vacancy supersaturation and crystal anisotropy

  • V. Hari Krishna


The gist of the paper is to introduce the other compelling factors for the boundary displacement which are dominant in the lower temperature regime such as non equilibrium vacancy concentration and anisotropy and to prove that the driving force due to the above factors is sufficient to induce grain boundary migration.
