... in subsequent AI exposure. These results point to the need of a critical corrosion fissure depth, stress, susceptible alloy temper, and possible critical localized corrosion site chemistry to produce sharp intersubgranular attack that would initiate/transition to intergranular SCC. aluminum-lithium-copper...

.... The ramifications of larger corrosion fissures towards SCC are as follows: SCC susceptible tempers may experience higher applied stress intensities owing to larger (i.e., longer and deeper) fissures at a given remote stress in addition to possibly exhibiting greater stage II crack velocities. aluminum-lithium...
