Abstract Fractal dimension of different parts of two fracture surfaces created by stress corrosion cracking in a high strength steel has been investigated by means of fracture profile analysis. The results show that the fractal dimension of the fracture surface corresponding to the sub-critical propagtion zone increases as the crack propagates. Therefore the process of stress corrosion cracking is the one during which the fractal dimension of the fracture surface increases.
