摘要

研究了具有不同晶格的各类钢材的塑性松弛和再结晶过程的特征。结果表明，在激光冲击区观察到了集体或二次再结晶的结构迹象，以及高速剪切或旋转塑性变形。研究讨论了在脉冲加载下与晶体结构缺陷行为相关的这些过程的条件。激光作用条件确保了钢结构的动态恢复过程。

Specific Features of Stresses Relaxation and Recrystallization of Steel under Laser Heating

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.
