Fractal characterization of fractured surfaces of a steel containing dispersed Fe sub 3 C carbide phase

Fractals are mathematical models of very irregular sets. In particular, the one-dimensional statistical fractals on a plane are useful models for fracture profiles. The vertical section method was used to obtain the fractal dimension D. The investigation were performed on a high carbon steel with ca...

Description
Summary:Fractals are mathematical models of very irregular sets. In particular, the one-dimensional statistical fractals on a plane are useful models for fracture profiles. The vertical section method was used to obtain the fractal dimension D. The investigation were performed on a high carbon steel with ca. 1% C after spheroidization annealing. The fracture surfaces were obtained by fracturing of Charpy V notch specimens, at the following testing temperatures: -20 deg C, -45 deg C, and -196 deg C. From the results obtained it may be concluded that the analyzed fractured surfaces have weak fractal properties, which are not dependent on the impact test temperature (D = 1.09-1.10, by the yardstick method).
