The features of plastic relaxation and recrystallization processes of steels of various types with different crystal lattices were studied. It was established that structural signs of collective or secondary recrystallization, as well as high-speed shear or rotational plastic deformation, were observed in the laser impact zone. The conditions of the course of these processes associated with the behavior of defects in the crystal structure under pulsed loading were discussed. The conditions of laser action ensured the dynamic processes of restoring the structure of steels.
