Crack in Bearing Steel

A. Grabulov
The movie visualizes the surface of a 30 micrometer long crack formed inside a bearing steel due to Rolling Contact Fatigue (RCF). The crack developped around an aluminum inclusion (not shown, but position indicated by large identation at one end of the crack).

The surface was modelled after a series of cross-sections of the material created and imaged with a dual ion / electron beam instrument.
