Fractal discrimination of toughness/fragileness on in-situ FGM of aluminum base by centrifugal casting
The fracture shapes are different on the various section spots along the gradient orientation of FGM. Leading the fracture analysis into the field of fractal, determining and calculating the fractal parameter, the variation of toughness and brittleness in sections of materials could be discriminated.
