Cryo treating blocks?

i would suggest it isn't just a surface treatment and given that the whole block is exposed to the mighty low temperaure it should have an effect on the whole structure.

chemical treatements..gases, liquid pickling nitriding etc and shot peaning are surface only

working, machining, hitting metal, work hardens it, It causes dislocations in the grain and tangles up the grain structure that tha atoms follow. makes me think the "working" should be done before treatment.

Cryogenic processing doesn't work harden it relives streses and it just makes it tougher realigns all the atoms in a nice structure of what I guess is their position of "best fit".

sounds like cryo last to me.


well felt nervouse about posting what i just said so went looking

The BIG chill - Cryogenic Metal Treatment Benefits May Not Be Visible But Are Real - Engine Builder Magazine.

you can't blieve evrything you read on the internet but this kind fits with my high school physics thinking... and i now know a bit more about it
