Jay Fisher's New Web Page on HT & Cryo

Jay, yes you stated it but I think the term is a moot point since electron microscopes are more available and have more features so more have them.

The term "shallow cryo" I wish would not be used because to me at least implies the formation of eta carbides .Without that it should be called by the old term "sub-zero" cooling .
You bring up some industrial factors which more often confuses the audience.That has been a problem I have after years of industrial work.

We have lots to learn about cryo and other HT factors .
Always treat each steel on it's own merits .Stick to just a few steels and experiment to learn their secrets.

Quick thanks to Jay for all his time spent on his website educating customers as well as me, a new knife maker (garage guy for about a year now). I have geared up in the workshop quite a bit and am turning out improved 440C blades with each batch. Just stuff for my family and friends - I am not threat to the many wonderfully skilled craftsmen I see selling knives on the ole "interweb"! I am a civil engineer by schooling - which may be interpreted as a nerd - so I love the technical stuff, although 55 pages on heat treat and cryo did take me numerous sessions to read! Thanks again for sharing your decades of knowledge with our industry.
