Notes:
The peculiarities of diffusion process and changes of long and short order parameters atan elastic and plastic deformation of compression and tension near grain boundaries withdisorientation axis 〈111〉 are studied by the method of molecular dynamics. Whirl displacements ofatoms destroying the order near grain boundary superdislocations are noticed at uniaxialdeformation of compression. The fracture of superstructural and structural order at uniaxialdeformation is accompanied by the deformation of amorphous area. Interdiffusion mechanism ischanged in the dependence on deformation, temperature and boundary types
