Cryogenic Technical Articles Options

[lmcchesney]

I have reviewed all the messages from the foum regarding cryogenic processing of engine parts. However, it lacks good/significant documentation regarding the different processes done.
Does anyone know the source of technical articles regarding this process.
There must be some University site with this information.
Yes, I have searched the MIT site without success.
Anyone have the information?
Thanks,

So far, the evidence that I have seen is all anecdotal. The bit about treated parts having harder Rockwell numbers is new to me, and very intriguing. It could easily lead to the sort of info that could convince me...

Some of the folks on the Racing Rennlist email list tried cryo'd brake rotors. The one application I remember was on a 944 (over 3,000 lbs in racing trim) and the owner found zero difference in the stopping power or life span of the cryo'd rotors versus the plain untreated ones.

At the very least, this says to me that the treatment is sensitive about its application or about how it is applied. It would be helpful to have a way to verify that whatever good things are supposed to happen inside the metal actually did...

I have also heard one metallurgist opine that "even if it did anything, the effects would be lost the first time you heat-cycled it." I think he was talking about rotors again, though. Engines are obviously at least a bit different.
