Abstract
The paper sets forth the possibilities for determination of reduction in area 9 and KCV based on the results of testing standard samples cut out across the direction of rolling on the sheet plane. A11 additional notion of lamellar cracking coefficient is introduced, which is the KCVzmax: KCVmax ratio in the entire range of transition temperature.
Keywords: low-carbon and low-alloy steels, anisotropy of mechanical properties, reduction in area, impact strength, lamellar-tough and lamellar-brittle fracture
