Cryogenic effects on bladesteels?

[TekSec]

I don't care what the metallurgists say, I'm gonna put all my blades in the freezer for 3.7 hours starting at midnight on the full moon soaking in chicken blood....and pointed at magnetic north. Or I can just send them out to a heat treater. The latter is preferable in my case

Make sure you are painted up in a loincloth speaking in tongues, and handling snakes, with your chicken teeth necklace on!

You moron, the best is to use virgin's pee. Of course that seems to have become a very limited in supply. I find chicken blood to not change my hardness a bit at least on my blades. Am I doing something wrong.

It helps if you stick the knife in the chicken and stick it in the freezer while the chicken is still alive. You see, one way or another you have to draw the bitter and vengeful soul of the chicken into the blade.

Yes, but then the exact timing of the chickens death has to be at the same moment that Mercury and Venus have to be exactly aligned...that's just way too much voodoo for me.

And Sam, after Ashokan I never see anyone forge in a loincloth again (Matt :barf: )

Most writeups I have found on the net have been produced by companies that are in the cryo business.

The following is not a sales pitch, but an independent study and after digesting it I gave up doing cryo on tool steels.

I mainly did cryo treatments hoping to gain toughness in A2 and D2. I like both at HRC 60 and am not willing to sacrifice toughness for a couple of points of hardness.

I will still do the cryo on request.

TecSec, we finally had what we were looking for - a sunspot with reverse magnetic poles that occured two weeks ago !!! That signals the start of a new cycle .So we have to revise the proceedures !

Try using this search, ten or more pages of the stuff rtj1981 came up with it. http://www.google.com/coop/cse?cx=017502325716702508313%3Ax783tv5e5y4&hl=en

nice mete
now i have to rethink everything
i was cryoing eveythign that i did to -1000000 f .00000000000004 K
but now im all messed up
let em know what the new way is would you

 

[mete]

No it's not that bad . Just reverse things .Turn your forge and anvil around and see that the blade is pointed the opposite way when you quench .

 

[butcher_block]

well i always wanted a reversing switch for my trusty KMG

Awww, man, now I have to move my freezer to the other side of the house...

It's even easier. Just forge with the other hand. This will put reversing, "edge-packing" (<<<another can of worms, with absolutely no scientific fact to back it up, thus voodoo crap), multi-phasic forces through the microstructure.

All of this resulting in fine grain structure, increased hardness and wear resistance. Of course, those three benefits are to the biceps of the arm you're now using to swing the hammer and have no benefit to the steel.

I edge pack all the time....am I going to go blind?:jerkit:

I noticed your hand doesn't have much travel to it.

Hey, there's a reason they make 3 fingered knives

 

[scottickes]

Three fingered? Aren't you still exagerrating just a little bit?

 

[scottickes]

and........we're way off topic now.
