Query: The Unit Cell Reconstruction and Related Thermal Activation Process
  within Coherent Twin Boundary Migration in Magnesium   By analyzing the interface defect loop nucleation and the interface
disconnection expansion in dynamic simulations, the elementary migration
process of coherent twin boundary of magnesium is identified to be independent
unit cell reconstruction. The atomistic pathways of the unit cell
reconstruction prove their collective behavior as a stochastic response to
thermal fluctuation at a stressed state, and also the onset mechanism of
interface disconnection gliding: predominant pure-shuffle basal-prismatic
transformation along with atomistic shear movements. The athermal shear
strength, the migration barrier, the critical length of disconnection dipole
and other parameters characterizing the thermal activation process are
reported.
