what's blue and brittle?
(OP)
actually, what's "blue brittle" testing (something to do with steel)? I'd ask my favorite metallurgist, but he's away from his desk.

"Blue Brittleness: Brittleness occurring in steel when in the temperature range of 400F to 700F, or when cold after being worked within this temperature range."

I remember doing some down and dirty tests for work hardening; this is years ago though. I don't remember the specifics but the process goes something like this.
Work Hardening produces a martensitic(?) condition, and that has a specific hardness, so perform a hardness test. If the parts fail (are determined to be blue-brittle / dynamic-strain hardened / work hardened) they undergo a strain relief heat treatment (or scrapped as the case may be.
