Stress corrosion cracking environmental alloy combinations

Environmental Cracking The problem of environmental cracking of metals and their alloys is very important. Of all the failure mechanism tests, the test for stress corrosion cracking (SCC) is the most illusive. Stress corrosion is the acceleration of the rate of corrosion damage by static stress. SCC, the limiting case, is the spontaneous cracking that may result from combined effects of stress and corrosion. It is important to differentiate clearly between stress corrosion cracking and stress accelerated corrosion. Stress corro-... 

Stress-corrosion cracking (SCC) is a fracture, or cracking, phenomenon caiised by the combined action of tensile stress, a susceptible alloy, and a specific corrosive environment, llie metal may show little evidence of general corrosion attack, although sl ht localized attack in the form of pitting or crevice corrosion may be visible. Usually, only specific combinations of metallurgical and environmental condi-...
