摘要：

The treatment conditions yielding steel with a natural ferrite-martensite composite structure are proposed. Structural steels having a banded ferrite-pearlite structure after hot rolling are analyzed. It is shown that the strength achievable by the composite is proportional to the volumetric fraction of the strengthening phase. Based on the experimental data obtained as a result of tension and dynamic bending testing, the fracture mechanisms of steels having the ferrite-martensite composite structure are discussed.
