The Fractal Research of 16MnR Steel Fatigue Fracture after High Temperature

Abstract:

In this paper, the computer picture technology was used for recovering three dimensions shape of 16MnR steel fatigue fracture. The fractal dimensions of the 16MnR fatigue fracture surfaces were calculated after high temperatures. The relation between the fractal dimension of fatigue fracture and heating temperatures, the relation between the fatigue mechanical properties and heating temperatures were researched. The relation between the grain size of 16MnR steel and the fractal dimension of fatigue fracture, and the relation between the grain size of 16MnR steel and the fatigue mechanical properties were discussed.
