Abstract

The fatigue crack growth behavior of pure magnesium has been investigated in laboratory air at room temperature. Two type of compact specimens were prepared from magnesium polycrystalline ingot, and two type of compact specimens with different notch orientations were also prepared from magnesium single crystal made by the Bridgeman technique. Two types of fatigue crack propagation behavior were observed in the magnesium crystals. When a notch isnormal to basal plane, a fatigue crack propagates though zigzag route withmany basal slip. In the case of notch parallel to basal plane, a fatigue crack propagates through straight route with {10 (1) over bar2} twin, and the value of DeltaK(th), is smaller than that of fatigue crack propagation with basal slip.
