I'm not sure your assertion is correct

<< Cryogenics substantively changes material properties, and domestic deep freezing involves temporary expansion and contraction. They are significantly different. >>
Why do you say this?
If your assertion were true, there must be some "threshold" temperature that "changes material properties" beyond just a "temporary expansion and contraction". So what would you propose as this threshold temperature?
And a few more questions:
- Would the threshold temperature be the same for all materials?
- Would the duration of exposure below the threshold temperature matter?
- Would the rate of re-heating to room temperature matter?
I would assert that things are perhaps not so black-and-white as "cryogenics" versus "domestic deep freezing"...
