Has any one herd of this.
I found an artical in Zoom (issue 61) that states, by freezing metal to below 196 degreez Celsius it can make metel up t 300% stronger.
It does this by disapaiting a substance called austenite from within the metal while the remainder is trasformed to martensite (four times harder than austenite) thus improving the molecular alingnment that relives stress in the metal.

(i almost sounded interlchical then)

If this is as good as they say it would be good for treating parts like my standard gear box is it is the weekest link in my chain at the moment.
I have heard of two places in australia that
do this so far an would like to know of more


more coments on this one would be grate
