Cryogenic storage vessels are periodically exposed to ambient temperatures and possibly elevated temperatures for varying periods of time, usually for several days, either for cleaning the vessels or for deriming the processing system associated with the storage vessels. The elevated temperature exposure may be as high as 200–250°F. Several of the new aluminum alloys in the aluminum-zinc-magnesium system rely on the aging effect at room temperature to achieve improved strength of the weldments. There is, therefore, interest in finding out what happens to these weldments when exposed to elevated temperatures over longer periods of time-simulating the intended useful life of such vessels.
