...Simge Gencalp Irizalp; Burcak Kardelen Koroglu The effects of two temper conditions (T4 and T6 heat treatments) upon the stress corrosion cracking (SCC) of AA6061 plates have been investigated in this work. AA6061 alloys were double-side-welded by the tungsten inert gas (TIG) welding method. SCC...

...Pierluigi Pagliaro; Michael B. Prime; Bjørn Clausen; Manuel L. Lovato; Bernardo Zuccarello In order to test new theories for residual stress measurement or to test the effects of residual stress on fatigue, fracture, and stress corrosion cracking, a known stress test specimen was designed...

... with mechanical properties. Residual stresses determined by the center hole-drilling strain-gauge method are reported in addition to electrical conductivity, stress corrosion cracking, fracture toughness, initiation fatigue, and tensile mechanical property variations. It was found that quenching into boiling...

... corrosion cracking (SCC) is a primary concern in the design of these canisters because tensile residual stresses will be left behind by the closure weld. Alloy 22 is a nickel-based material that is particularly resistant to corrosion; however, there is a chance that stress corrosion cracking could develop...

... to the heating and cooling associated with an operating cycle, with implications for the development of cracks in the tubes due to stress corrosion cracking. The analyses also show that axial stress in the carbon steel layer is compressive at the fireside tube crown and tensile in the membrane, which provides...
