... that these materials were heavily sensitized with embrittling phases present at the austenite grain boundaries. Improper annealing processes at the manufacturing plant likely caused the sensitization of the microstructure.

... A Charlottesville, VA 22903 USA ABSTRACT Sensitization of 5xxx series aluminum alloys is a significant concern for the U.S. Navy as the alloys have found use in a variety of ship structures for improved strength-to-weight ratios and enhanced corrosion resistance.

Although the stabilized austenitic stainless steel such as UNS S34700 (347) or UNS S32100 (321) resist sensitization up to higher temperatures, especially with post weld heat treatment (PWHT), they have less NAC...

... ABSTRACT Al 5XXX series aluminum alloys are being used in naval military applications, and being exposed to outdoor environments. With sufficient time and temperature exposure, these alloys undergo a process in which a secondary ß phase forms at the grain boundary that sensitizes the alloy...

... ferries and patrol boats as well as in Navy ships have shown that the 5XXX series is prone to elemental migration and phase transformations at only slightly elevated temperatures (i.e., sensitization), leading to localized intergranular corrosion and stress corrosion cracking. In order to maximize...
