From what has been written it would appear that a change to the physical state of metal could be loosely referred to as annealing!
So, heat annealing (heating and cooling), cryo annealing (freezing and warming), and electrical annealing, all change the physical state of metal (and other materials) and even the temper of the metal. It would appear that they could all be loosely grouped under the heading of annealing :)
I have tried Home freezing but it seems to be a temporary annealing or have you found a way that it is permanent? :)
