quenching in alcohol


Recommended Posts

See quenching into Jack Daniels, now that would be a waste, "Tennessee wetforging" however can be forgiven (late nighters at the fire and brimstone hammer in might remember that one!).

 

I wonder if Guinness is a slower quench than bud light? :D

 

actually i dont think it would be, because of the gaseous nature of the nitrogen

I wonder if the vapor phase would be increased quenching into a carbonated water?

Let not the swords of good and free men be reforged into plowshares, but may they rest in a place of honor; ready, well oiled and God willing unused. For if the price of peace becomes licking the boots of tyrants, then "To Arms!" I say, and may the fortunes of war smile upon patriots

It is done with some knife blades -- in that case mainly to eliminate retained austenite, though. Not so much for stress relief, as far as I know, though that may be a good side effect.

 

Cryo,

 

Well, it's not, really to eliminate retained austenite but to continue making martensite with austenite that would be untransformed and retained at ambiant temp, most of the hi-carb steels have a Mf point (Martensite transformation finish temp) located far under ambiant temperature...

If you can reach a -100°C, most of the hi-carb steels used in knifemaking would be fully martensitic -> No retained austenite, less brittle, and more martensite -> harder...

Hope to be clear (French frog inside) ;)

liquid nitrogen is minus 196C but probably not much heat capacity

 

 

Liquid nitrogen is a very slow quench because it goes right to vapor. creates a very long and stable vapor phase. The same would be said for alcohol - it would have a long vapor phase. Not a good idea.

Yes - vapor phase would be elongated in carbonated water....
