Metal that changes color upon impact
Metal that changes color upon impact
(OP)
Does anyone know of a metal that changes color when struck and eventually goes back
to it's original color? An example of this is a material that is as strong as steel
and when you strike it with a hammer it darkens at the spot of impact and then
returns to its original state after a short period of time (say < 30 seconds).
I'm not even sure if such a material exists that is strong like steel. I know
that piezoelectric materials change color under stress but they're not very strong.
I need something that can withstand a powerful impact.

Even with ceramics, which have very poor thermal conductivity, short duration thermal effects fade within about 20ms; this is with a 30mJ laser with 11-ns pulsewidth, which is a peak power of 2.2 MW.

enough to withstand repeated impacts (1000's).

by adding circuitry although it is something to consider.

RE: Metal that changes color upon impact
point so there is not much I can say until I get a patent application in the works. I'd be more than happy
to speak with someone via private email though (vavalencia --at-- gmail.com) if you need more details.
Also, a big thanks to all that have participated in this discussion. I really appreciate the help!
