摘要：
It was found that overheating (1200 degrees C, 4 h, slow cooling) of low-carbon low-alloy steel Fe-C-Cr-Mo leads to the formation of a Widmanstatten structure and an increase in strength by 1.2-1.5 times while maintaining high ductility. The relationship between changes in the steel mechanical properties and the Widmanstatten' dislocation structure features are discussed.
