OBSERVATIONS ON THE STRESS-CORROSION CRACK PROPAGATION CHARACTERISTICS OF HIGH-STRENGTH STEELS

Abstract

The relationship between stress-corrosion crack velocity and crack- tip stress intensity is discussed. In most high-strength steels there is a wide range of stress intensity over which crack velocity is essentially constant. Methods of estimating this velocity are described. Values for a variety of high- strength steels are presented and the effects of metallurgical variables are indicated. Implications with regard to testing procedure, crack morphology, and service performance are outlined.
