| Abstract: | In impact toughness test the fractal dimension fractured surface specimen was determined by secondary electron line scanning and digital image analysis separately. The relationship between impact toughness and fractal dimension fractured surface in the 30Ni2B steel has been studied. The result shows that the impact toughness of specimen is directly proportional to fractal dimensions Dse and DH, that is, the impact toughness increased with increasing of fractal dimension. |
