Please don't think of cryogenic processing as a tempering process. First of all, it has been decided by the American Society for Materials that the process is not a tempering process. It really goes further than that. Steels display a shift of retained austenite to martensite, it does relax residual stresses, and it also creates very fine carbides in the matierial if done correctly. But none of these explain the affect the process has on silver, copper, etc. Los Alamos National Laboratory is looking into changes in the crystal lattice structure that might account for why the process works.

Recent research by the US Army Aviation and Missile Command shows the process has great potential for increasing the life of helicopter gears (and we all want them to last as long as possible, especially when airborne). A recent paper by a large European auto components manufacturer concluded that the reasons for the benefits could not be seen in the microstructer of the material, but had to be sought in the submicrostructure.

By the way, ASM concludes that the proper name for the process is cryogenic processing or cryogenic treatment, and that the use of the phrase tempering is missleading.

Sorry about the length of this, cryo is my field, and I feel there is a lot of misinformation about it out there.
