Fatigue behaviour of AZ31B magnesium alloy adopting screw-type notch sample was investigated using high frequency fatigue tester.S-N curve of AZ31B magnesium alloy under the test condition is presented and its fatigue limit based on 107 is 15.3MPa.Contrast study on fatigue behaviour between screw-type notch sample and smooth sample is conducted.Fractographs of the fatigue fracture samples are observed using scanning electron microscope and fracture mechanism is analysed.The results show that high cycles fat...
