Abstract

Purpose. Besides having complex of high mechanical properties a modern structural steel should have a high level of resistance to brittle fracture. That is why the study of the influence of various parameters on the fracture behavior of structural steel is the primary purpose of this article. Results. The influence of the basic microstructural parameters on the formation of the fracture surface of low-carbon steels was analyzed. Undertaken studies on fracture surface’s character of low-carbon steel 10Г2ФБ confirm the presence of fracture surface formation peculiarities.
