Vertical section method has been used to measure the fractal dimension of cyclic creep frac- ture surfaces of rotor steel 34CrMoA at 550℃.The relationship between fractal dimension and cyclic creep properties has been analyzed.The fractal dimension is dependent upon the power product of minimum creep rate and rupture time,and satisfies the linear function with rupture strain.
