Prediction of working stress of cold-work tool steel

Working stress depends on fracture resistance and on deformation resistance. Fracture toughness represents fracture resistance, whereas yield strength and modulus of elasticity characterize deformation resistance. Fracture toughness and yield strength directly depend on steel microstructure, opposite modulus of elasticity, which is the most insensitive property to structure transformations in steel. The main influence factors on fracture resistance and on deformation resistance are presented in this paper, as well as the methods of fracture and deformation resistance usage in design of safety of engineering component application.
