Az91d Magnesium Alloy

Strain rate change tests were performed under uniaxial tension-compress cycle loading during low cycle fatigue of AZ91D magnesium alloy using plastic strain as the control variable. Results show that the cyclic softening phenomenon is appeared in testing materials when cycle strain amplitude is less than 0.4%. With the increase of the cyclic strain amplitude, material displays obviously cyclic hardening; at the same time, the additional strengthening degree of materials is increased. Further study found that the slope of the curve is unchanged when the strain amplitude is more than 1.0%. The changes of strain rate has a little impact on the low cycle fatigue life of AZ91D magnesium alloy, conversely, the changes of strain amplitude has a great influence on low cycle fatigue life on the material. With the improvement of strain amplitude, fatigue life is reduced obviously. In addition, the Coffin-Manson formula fitting equation has good consistency with the experimental data, which is used in low cycle fatigue prediction life.
