Abstract
A quantitative and qualitative fracture analysis has been carried out on 40Kh and St.3 steel specimens. The existence of a certain loading rate threshold has been established whose exceeding changes the regularities of the effect of the loading rate on the shape and parameters of the fracture microrelief. This corresponds to the speed dependence of dynamic crack resistance of steel.
