Abstract
The relationship between the fracture surface, irrpact energy, microstructure and fractal dimension of bearing steel by isothermal quenching blow the low bainitic range at different temperatures has been studied in this paper. It revealed that the fractal dimension varied linearly with the roughness of fracture surface, total length per square micron and density of tear ridge and impact energy which were affected by both the size of acicular bainite and amount of martensite.
