Abstract:

The role of weakened surfaces parallel to the plane of rolling in the formation of delamination cracks in the course of impact-toughness testing of steels with the bcc structure subjected to high-temperature thermomechanical treatment has been theoretically substantiated. A mechanism of increasing impact toughness during the formation of delamination cracks has been described using 08Kh18T1 steel as an example. It has been shown that the stress state that arises in a material with weakened surfaces can be modeled using composite specimens.
