摘要：
We establish the relationship between the electrochemical characteristics of the stage of crack initiation and the susceptibility of various types of stainless steels to corrosion fatigue and show that the proposed parameter of relative strain fracture can be used as a criterion of corrosion-fatigue fracture of steels caused by the accelerated dissolution of microstrained regions on their surface. We also deduce analytic relations for the evaluation of the corrosion-fatigue limit of passivated steels. The accuracy of the proposed formulas is never worse than 12%.
