Why "Cryo" anything?

Geoffkait,
Please go through my post again. Cold tempering requires heat treatment cycle. Not cooling from room temperature, which is what's in vogue right now in Audio.

Cello,
Please try to under this. When you make a scientific claim such as DBT testing, the test result must be statistically significant. Otherwise, it's just pseudo-science.

Ejliu,

I think I'm beginning to understand the purpose of you posting this thread. Maybe I have it wrong and I'd welcome some clarification if so, but I think this is the type of troll meant to start a fight. Let me explain.

You state that "Cold tempering requires heat treatment cycle". Not true. It's not a matter of being in vogue either. While I concentrated on deep cryo immersion of engine blocks and reciprocating assemblies in order to stay under the radar, the principles remain the same. If one were to heat treat a block and then cryo treat it the resultant brittle casting would last less than sixty seconds after start-up and subsequent shatter. Heat treating is a part of the equation only if you wish to add hardness. In fact, most applications of cryogenics don't want the material to also be hardened. If only you would do a small amount of research you'd find this to be true.

Large firms like Rockwell, IBM, 3M, etc. cryo many parts and have participated in important research. The findings are yet to be fully understood. An example is the theory that molecular reorganization occurs through cryo'ing. The results seem to prove this because holes in silica wafers become filled after. They don't know why. Science hasn't gotten that far yet.

Your mistaken claim that heat treating is required destroys any validity you may wish to have garnered with your diatribe. Obviously, you ain't no scientist. In a hobby where what matters is what one hears you conveniently dismiss anecdotal evidence. Our ears will always and forever be anecdotal devices. They are not meters. Your proposition is totally absurd and I'm calling you on it. BTW, I'll be glad to have some brake pads heat treated and cryo'd as a gift to you as long as you promise to install them and hit the brakes hard the first time at about 140 entering a curve.

To my simple way of thinking discussions like this could be fun and interesting and as science evolves eventually enlightening. Nobody needs to agree about any aspect of these technologies. At some point most of us learn that life is too short for this kind of twisted enjoyment. I wish you luck in getting there.

Ejliu,

I would think cryo treatment comprises a complete cooling and (re)heating cycle; i.e., the return to room temperature constitutes "heating" in my book. No heating above room temp is required, but I suppose it could be used along w/ cryo in some applications like hardening of tools, etc.

Cold tempering (as I use the term) has been around for a very long time; what is in vogue, as you say, in audio is same process (or should be) as Cryopro and other outfits have been doing for years. Actually cryoing has been around in audio for quite, more than 6 or 7 years, now that I think about it, Meitner, Walker, and many others, some more public than others. I first started using Crypro about 12 years ago, about the time that some big guns like Holleywell were experimenting with cryoing transistors. (Never did hear about their results heheh)

Nice post. Out of curiosity, is Jimmy Neutron your less intelligent brother?
