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.

I'm not going to offer any kind of post with regard to positive or negative effects of cryo'ing bits and pieces of audio gear since it's pretty controvertial. Many believe in it and many don't. Most are closed minded on the subject independent of which camp philosohy they ascribe to. What I will offer is asking you to do your own investigation into why NASA, NASCAR, INDY and a miriad of other world class engineering teams DO cryo? Sometimes our educations trap us.
Because the people who do it can then have a reason to charge you more for the product.
