%X According to fractal method,the present paper analyses the relation between fractal dimen-sion and tensile property on the condition of tensile test,and discusses the influences of microstructures onfractal dimensions.The paper also compares the relation between fractal dimension and tensile propertywith the relation between fractal dimension and Charpy impact toughness.The experiment shows thatthere in only a qualitative relation between tensile property(elongation,tensile strength and yield strength)and its fractal dimension.Elongation is directly proportional to fractal dimension,strength(tensilestrength and yield strength)is inversely proportional to fractal dimension.Microstructure has an impor-tant influence on fractal dimension.Fracture model also has an important influence on fractaldimension,fracture feature and their relation.
