Abstract

In this review, the fractals in the fractography is described, using brittle fracture surfaces of chromium and molybdenum, and stress corrosion cracking surfaces of SNCM 439 steel. It is emphasized that the quantitative fractography at the atomic region is opened, combining scanning tunneling microscopy with fractal geometry.
