Why "Cryo" anything?


Ok. So far, I have yet to think of a good explanation for "Cryo" treatment to enhance anything. Can someone explain this to me?

For background, I have a Master degree in Material Science Engineering. Here is my explaination why just "cryo" won't work.

At room temperature, the metal is already solid or frozen. Freezing it further won't do much. Most metals requires high temperature to cause any change in the microstructure or grain size/orientation/distribution. Simply freezing it for a few minutes will not change how it operates after the metal returns to room temperature.

Excellent post, Lugnut...I figured this debate was just getting us all a bit too excited.

I do differ from your opinion that the "naysayers" are suggesting that there is no difference in sound. Perhaps I'm only speaking for myself (I don't think so?), but no one has directly said that cryo'ing does NOT make a difference. Some of us have tried it, some have not. My take on the discussion has been that some of us with specific knowledge of materials have questioned the "reasons" some have attributed to the difference, not really that there are no differences. This certainly doesn't rule out mechanisms we are unaware of, but the metallurgy is very well understood, so I'm fairly certain that we need to look elsewhere for the answers.

Autio, I agree that our ears are wonderful devices, but one component of hearing is perception and this is not always reliable. I've found my moods, sickness, exhaustion from a workout, etc all affect how and what I hear. Also, when I listen critically with a friend, sometimes afterward I find myself reversing my thoughts on further listening by myself. What I'm saying is MY hearing/perception is not always as reliable as I would like it to be. Maybe others don't have this problem? Ultimately, it is still the only tool we have to measure our enjoyment of a given component. I'll leave it at that.

Actually it would be violating a patent infringement to have Ejliu treat a brake pad and charge for the process.
This is a patented process and is used by many fleets to reduce the maintenance cost on high usage vehicles.
I have not participated in this discussion because one of my client companies produces products for the automotive industry that uses cryo processing.
I cannot make any claims as to improvements in audio equipment. The improvements in machining, stress relief longevity and resistance to corrosion are substantial and have been tested/ patented and are repeatable. We have many clients in the aerospace industry the military, high performance auto and bio medical. You can look up the patents on sparkplugs, brakepads and human joint replacements.
Ya, my joint is getting down to the roach; probably needs replacing. But how do you keep it lit while its being cryoed? Now I know why everything sounds better.
Cryo works, I tried it with tubes,the difference is
huge,those who cant hear it,either they dont want to
hear it, or their ears are not train, or maybe they
are scare to try it.
