Description

Electron scanning microscope picture in false colours.

This is the result of a vibration test on a burning tungsten coil in a lamp.
Due to the temperature, movement at some specific point and probably a cavitation effect in the grain boundaries the metal is pushed away from its normal place and build this kind of needle structure.
The largest needle is 40µm high =D
Original picture by me with a JEOL JSM 6360LA, colours by me =)
