摘要：
The fractal dimension variations of several tension fracture surfaces of a duplex stainless steel broken at room temperature has been studied after several aging treatments performed at 475 degrees C for 1, 2, 6.5, 12, 24, 40, and 120 h, A dimple type of fracture mode was observed for small aging times and transgranular as well as dimple rupture for 24, 40, and 120 h of aging. The higher the time of aging is, the smaller the fractal dimension and the true fracture strain. An expected reduction of the strength with the time of aging was observed.
