Curated summary
This open-access paper combines saline pre-corrosion, fatigue tests at multiple loads, SEM and surface-profile inspection, and ABAQUS analysis to study how pit geometry affects stress intensity and residual life in 42CrMo (AISI 4140) steel. A regression relation is coupled with the Paris law for life prediction, and pit size is proposed as a damage index. Disc-spring use still requires matching the actual material, stress state, and environment.
