Had a chance to talk to one of the metallurgist guys at work today. Apparently even in the metallurgist community is split over cryo treating. In practice it will reduce the internal stresses and therefore reduce/eliminate the formation of microcracks under heat cycling. However according to the guy I work with there is no scientific proof of the effects of cryo treating to the microstructure of the metal.
In other words, it works but no one can prove 100% why.
