I See Civillity Is Wasted With You

Clifff,

So much for expecting civility from you, oh well. You have this obsession with being sarcastic with those who don't agree with you 100% so I'll just state the facts and stop trying to be civil, as it's wasted upon you. You act like you made a great discovery in claiming "This is a direct cut and paste from their web-site SELLING Cryo!" when I provided a link to that site. Cryoing benefits have been scientifically documented as anyone with access to a PC can see for themselves. But I'll repeat myself just for you....

The latest research data on cryogenic tempering confirms the long standing theory that cryogenic treatment significantly enhances cutting tool life. Dr. Joan Alexzndru and Dr. Constantine

Picos of The Polytechnic Institute of Jassy, Romainia, utilized the latest scientific equipment available, a JEOL IXA-5A Electron Probe, a Diffractometer, a Quantimet 720 Quantitative Microscope, and a Chevenard Differential Dilatometer to supply the following results from the extensive study.

The study involved 7 samples (A-N in Fig. 2), each subjected to a different tempering cycle as noted. Each sample was the equivalent of M2 steel; each sample had carbide particles physically counted, both before and after the deep cryogenic treatment. The team then measured the samples with the equipment above, and with standard metallurgical evaluation testing. The results confirm with tangible evidence the carbide precipitation in cryogenic processing.

All the metal samples were taken from identical batch stock. The sample structure was comprised of .83%C, .38%Mn, .3%S, 4.1%Cr, 5.1%Mo, 1.9%V, and 6.3%W. Samples were all simultaneously standard heat treated at 1230° C, then oil-quenched. Four of the pieces were then subjected to the cryogenic cycle at -70° C with varying tempers added after cold soaking.

Findings

The results of the testing conclude with the following findings and analysis comparing standard heat treating to heat treating with the addition of shallow cryogenic soak:

Austenite decreased from 42.6% to 0.9%.

Martensite increased from 66% to 81.7%.

Carbides increased from 6.9% to 17.4%.

Mean number of carbides counted @ 1mm sq. increased from 31,358.17 to 83,529.73.

Number of carbides less then 1um in size increased from 23,410.24 to 69,646.09.

Rockwell increased from 60.10 to 66.10.

Tensile strength increased from 86.0 to 244.46.

Bending strength increased from 86.0 to 244.46.

KCU (resiliency) increased from.668 to 1.18.

HRC 675° C after 20 minutes keeping: 56.88 to 62.25.

Durability of the cutting time increased from 20 minutes to 45 minutes with a shallow cryogenic cycle.
====================================================================
Now considering that the cutting life of a tool was extended to just over double it's normal life expectancy, I think a circuit boards reliability will increase dramatically over a tad over the few minutes you're sarcastically suggesting.

As for your other sarcastic comment about this being: Once again a leap of faith is being made between "improving life of missle pcbs" and things sounding better. I stated my POV on cryoing creating better sound quite clearly 1)I do not know for sure 2) I'm still undecided myself, but I am leaning towards believing it does affect wires, circuit boards, tubes, transistors, inductors etc. 3) Thus the question is really not does cryoing affect these components, but rather is the affect a postive one that leads to a more realistic replication of live music? That still remains a question everyone has to answer for themselves. All 3 of those comments are a far cry from taking a leap of faith that things WILL sound better like you suggested I did.

You should dramatically increase your reading comprehension BEFORE responding to me again as it's quite obvious you're incapable of understanding what I am actually saying, prefering instead to act in the typical British manner of being sarcastic, arrogant and pompous even when I spoke civilly with you! Stop acting like a bloody twit and respond to what I actually say and not what you want it to mean. And you wonder why I talk to you like I do....
