Abstract
The characteristics of fatitue-fracture resistance of nodular cast irons in the stages of initiation and growth of a macrocrack are determined within the framework of the power and deformational approaches checked for structurally homogeneous materials. According to the data of direct measurements of the opening displacements of notches and cracks, deformational parameters are more sensitive to the influence of the system of graphite inclusions in the prefracture zone than formally computed power parameters. It is shown that the effect of graphite inclusions on the mechanics of fatigue fracture of high-strength cast irons is ambiguous: positive for low loading amplitudes and negative for high amplitudes. We also demonstrate that the model of initiation and growth of fatigue macrocracks proposed earlier is universal.
