Technical and scientific discussion of amps, cables and other topics.

Ignorance is fuel for such nonsense.

<< Cryogenics substantively changes material properties, and domestic deep freezing involves temporary expansion and contraction. They are significantly different. >>

< Why do you say this?

I suspect he said it becuase it is established scientific fact.


>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?

Yes there are threshold tempuratures. If you want to know what they are I suggest you consult a genuine metallurgist or some literature on the subject.

>And a few more questions:

- Would the threshold temperature be the same for all materials?

I don't need to consult any metallurgist for this one. No.


>- Would the duration of exposure below the threshold temperature matter?

That would be a question for an expert.


>- Would the rate of re-heating to room temperature matter?

I can answer this one. Soemtimes yes sometimes no.


>I would assert that things are perhaps not so black-and-white as "cryogenics" versus "domestic deep freezing"...

I would assert that this stuff has already been investigated by people who actually know how to inverstigate these things.
