内容記述 |
In the TMCP steels rolled at the finishing temperature in austenite-ferrite region by the Non-AcC type TMCP method, it becames clear that the fatigue fracture surface had a lot of micro-separations, and fatigue crack propagation was prevented by micro-separations in the case of propagation in the direction of plate thickness. In this study, the authors investigated on the behavior of surface crack propagation using three TMCP steels with different SImax, and proposed the method of crack propagation analysis considering the effect of micro-separations. The results may be summarized as follows: (1) As SImax increase, propagation pattern of surface crack become shallow. (2) The macroscopic fatigue crack propagation can be analyzed with the assumption that the fatigue crack propagation in the direction of plate thickness passes through between estimated microseparations. (3) This estimation method shows the good agreement with the experimental change of aspect ratio for surface crack. |
