| Abstract: | This paper has studied the fracture features of the specimens of functionally gradient material Al-Fe alloy with the different sections.Based on Descrete Fractal Brownian Random model,the fracture has been studied by using the method of multiscale fractal analysis.The research results show that the fractal parameter H values of the fracture surfaces are also gradient distributing. It shows that the toughness of the alloy is gradient distributing. |
