Fractal dimension of fracture surface and superplasticity of 7475 Al alloy

The fractal dimensions of fracture surfaces are presently measured by a vertical section method, for the case of the 7475 Al alloy, under various superplastic deformation conditions. The results obtained constitute a quantitative description of the fracture surface's roughness; a higher fractur...

Summary:The fractal dimensions of fracture surfaces are presently measured by a vertical section method, for the case of the 7475 Al alloy, under various superplastic deformation conditions. The results obtained constitute a quantitative description of the fracture surface's roughness; a higher fracture surface fractal dimension corresponds to greater roughness and superior superplasticity.
