cryo-treated steel



On Wed, 12 May 1999, Dewey Dykstra, Jr. wrote:

It's the mechanical properties of the material the instrument is made of
which change, hence its resonances, etc. Makes a change in the sound
spectrum not the pitch of the notes unless the physical dimensions of the
instrument change. The sound of these instruments is somewhat more than
just a vibrating air column.

I remember when this "cryo-hardening" stuff first came out about a decade
ago regarding steel tools. Has anyone seen a good metallurgical article
on the phenomena? It makes sense that heat-treating of metals might cause
a phase change in crystal structure, or at least allow small crystals to
grow larger. I can't imagine what chilling might do. Perhaps the stress
of nonuniform contraction is equivalent to giving the surfaces a vigorous
hammering? If the metal was cooled slowly and uniformly, would the
desired effects still arise?

(Below is the search result for +"cryo-treated" +steel. It looks like
edged-tools are not the only things being "dipped." Rifles? Bicycle
frames???)
