Abstract
Investigation results are given on fracture toughness based on the deformation criterion for the most common domestic low-alloy structural steels of different thicknesses. An approach to evaluation of the brittle-tough transition temperature depending on the thickness of the investigated rolled metal is suggested. Shift of the basic deformation δ1c-curve depending on the thickness of the rolled metal and its standard strength characteristics was experimentally verified.
