چکیده انگلیسی
The environmentally assisted cracking behavior of dissimilar metal (DM) welds, including Alloy 52 - A508 and Alloy 82 - A508, under simulated BWR coolant conditions was studied. Effects of postweld heat treatment (PWHT) on the SCC and corrosion fatigue crack growth rates of DM welds were evaluated. PWHT brought about a change of the carbide precipitate distribution and strain localization, thus leading to a redistribution of the weld residual stress. It is concluded that Cr content in the weld may not be the sole factor governing the SCC resistance; the localized strain concentration could also play an important role.
