Abstract

Abstract—The fracture profiles and microhardness distribution in some regions of the compression region of Charpy samples of a high-viscous steel with a filamentary structure formed by the non-recrystallization controlled rolling with accelerated cooling have been studied. The mechanism of the plastic flow in the compression region of impact samples with different types of notches has been investigated. It has been shown that, as a result of intense plastic flow, two plastic hinges with axes containing a high density of slip lines appear in the compression regions.
