I search on various steel topics every so often to pick up new information. Cryogenic treatment of tool steels is one of my interests. I would like to know more about the nature of the transition, both from the physical and chemical side. I ran across this article yesterday and it answered several questions I have had.

Most things I turn up in searches and on different forum discussions take the form of testimonials and are presented from one side or another of various positions. This article is refreshing in its scientific approach and I highly recommend it to those who have an interest in getting more information without a sales pitch.
I have been using dry ice treatments for years and will probably continue, although I am questioning whether it is really needed. I remember reading a comment from Bob Dozier a few years back that if the heat treatment is right, cryo is a waste of time and merely covers up poor heat treatment. Of course Bob is not opinionated
