Piezo effect in metals?

Is the piezo effect only in crystalline substances?

Why does metal, when bent, generate heat?

Is there any change in the resistance of a metal when compressed? Or perhaps a spring (coil type)?

Yes. The crystal requires a lack of a center of symmetry.

It is the conversion of mechanical energy into heat.

Probably.
