...-corrosion cracking. Stress corrosion wasn't a concern in this application because loads on the surface exposed to the aqueous environment would be compressive — surfaces under compression aren't subject to stress corrosion. I was then advised about a type 440C part that had developed stress corrosion...

... or intergranular by adjusting the pH of aqueous solutions in which these alloys are immersed. The crack propagation behavior of SCC systems is often depicted by the crack growth rate as a function of the applied stress intensity, a v - K curve. Figure 4(a) shows a schematic v - K curve, and Fig. 4(b...
