The criteria for stress corrosion crack branching in high-strength steels are shown to be (1) a constant crack velocity and (2) attainment of a critical stress intensity Klb. For the steels investigated, values of K,b I K,,,, range from 2 to 4. This indicates that when K,, /K,, exceeds 0.5, rapid br
The crack propagation velocity in corroGon fatigue (du/dN), were measured on the Ni-Cr-Mo steel quenched and tempered at 473 or 773 K. The steel with high sensitivity to delayed failure reveals the largest (du/dN), under square load and the smaller (da/dN), under positive saw tooth load. The frequen
