Изучена микроструктура стали 05G2B (после различных обработок), определены размеры структурных компонентов. Определены механические свойства стали для образцов, вырезанных перпендикулярно и параллельно направлению оси прокатки. Построены последовательные кривые ударной прочности и исследованы поверхности исследуемых образцов стали.
The explanatory note contains: 70 pages, 16 figures, 4 tables, 51 a literary source.

The purpose of this work is to study the structure and complex of mechanical properties of steel grade of strength X80 in the initial state and after low-temperature processing.
The microstructure of steel 05G2B (after different treatments) has been studied, the size of the structural components has been determined. The mechanical properties of steel for samples cut perpendicularly and parallel to the direction of the rolling axis are determined. Serial curves of impact strength are constructed and the surfaces of the samples of the steel under investigation are investigated.
