RELATIONSHIP BETWEEN SUPERPLASTICITY OF 7475Al AND FRACTAL DIMENSION OF FRACTURE SUR-FACE MEASURED BY VERTICAL SECTION METHOD
垂直截面法测量的断口分形维数与7475 Al 合金超塑性的关系

Fractal dimensions of fracture surfaces of 7475 Al were measured by verticalsection method when the alloy was deformed under different temperaute,strain rate andgrain size.The results show that the higher the fractal dimension of fracture surface,thelarger the elongation to fracture of the alloy.
