Abstract U-bend and axially loaded tensile-type specimens were used in stress corrosion tests performed in boiling 140 C (284 F) magnesium chloride solution. The experimental ferritic alloys tested contained 17 to 25% chromium, 0 to 4% nickel, 0 to 2% copper, and 0 to 5% molybdenum. Alloys essentially free of nickel and copper did not undergo stress corrosion cracking. (Tests on Types 430 and 434 stainless steels confirmed this behavior.) However, alloys containing more than 1% nickel or 0.5% copper were subject to transgi anular stress corrosion cracking in boiling magnesium chloride solution. Critical concentrations of copper and nickel that produce susceptibility to cracking were determined at various chromium and molybdenum levels. Experiments at controlled potentials indicated that cracking in boiling magnesium chloride was not the result of hydrogen embrittlement.

Shock Peening

A slow strain rate tensile (SSRT) test was used to investigate the effect of laser shock peening (LSP) on stress corrosion cracking (SCC) behavior of the 304 austenitic stainless steels (ASSs) in acid chloride solution. Mechanical properties and fracture morphology evolutions of the 304 ASSs were studied as a function of the pulse energies through slow speed tensile tester and scanning electron microscopy (SEM). The results showed that the percentage elongation after fracture increased significantly as the pulse energy rose. Fractographic examination revealed that all the samples appeared a tendency to SCC in the given conditions, but specimens treated by LSP had better resistance to stress corrosion.
