Descrição: The article describes the nucleation and development of plastic deformation in a titanium crystal subjected to ultrasonic impact treatment, using the molecular dynamics method. The regularities of surface roughness formation and microstructure refinement in the surface layer of commercially pure titanium are identified. It is shown that surface plastic deformations of a titanium sample proceed by the mechanism of plastic plowing, accompanied by dislocation glide and twinning. The mechanism of phase transformations associated with the formation of stacking fault is demonstrated by molecular dynamics.
