摘要：
in the present study, the results of fatigue tests with the magnesium alloy AZ31 (ISO-MgAl3Zn1) in the material states base metal, heat affected zone and weld metal obtained under strain control at room temperature within a range from 2 . 10(2) to 5. 10(6) cycles are presented. The fatigue behaviour was characterized by the Coffin-Manson-Basquin equations and the stress - strain behaviour by the Ramberg-Osgood equation. The data can be used to assess welded magnesium joints according to the local strain concept.
