| Abstract: | It is found that there are sources for the bend fatigue mainly dis-tributed in the edge of specimens and caused by inclusions and micro-voids. Inthe fatigue fracture zone, the regularity of the crack extension is attributed toF-R model. The quasi-cleavage fracture or quasi-fracture occurs in instantaneousrate fracture zones. |
| Keywords: | fatigue fracture austempering/ductile iron |
