I think what is meant is that the crystal structure of the compound is
"aligned" or unstressed. It is suppose to work the same as when you temper
steel - you heat it up so as to unstress the metal and make it stronger.
When a clarinet key is power forged - a giant weight or pnuematic
press comes down on a piece of metal and forms the key - there is stress
built into the molecular latice of the metal. If you heat that key up -
anneal - you relieve some of that stress in the molecular latice, so the
key is stronger. The deep freeze method is suppose to work like that. I
have some literature on the process somewhere - I'll look for it this week.
My engineering books are 600 miles away in my mom's attic in Milwaukee -
I'll check those next time I'm in at Christmas.
