WebStress corrosion cracking may occur at a stress intensity threshold called K ISCC for a particular metal environment system. The effects of air fatigue and stress corrosion cracking on corrosion fatigue become apparent in dn/di vs log ΔK curve and their shape may change depending on which of the above is predominant. Cyclic-dependent fatigue ... WebStress corrosion occurs while material is in a corrosive environment and tensile stresses are present. All metals have different tensile limits/ranges, and the closer to the height of this limit the more likely it is for stress corrosion to occur. An example includes any processes that include High/Low temperature changes/cycles.
