AZ-based Mg alloys are produced by adding aluminum and zinc (Zn to pure Mg. Appropriate amounts of additives may improve the strength, castability, workability, corrosion resistance and weldability of these alloys.
In addition, AZ based alloys have high formability and weldability and ZK-based Mg alloys, which are produced by adding zinc and zirconium to Mg, have a higher hot-workability than other materials.
AM series alloys, which are produced by aluminium and manganese to Mg, have good combination of strength, ductility, energy absorption properties and castability. Multiaxial fatigue design analysis on automotive Mg-alloys will be conducted on two extruded alloys: AZ31B and AM30.
