Abstract

This study investigates the effect of zinc (Zn) and silicon (Si) in AZ91 (2% Al,1% Zn) and AS21 (2% Al, 1% Si) magnesium alloys on wear resistance and machinability.In magnesium alloys, the effect of hardness, wear resistance and machinabilitywas investigated by establishing the impact of 1% zinc (in AZ21) and1% silicon (in AS21) within the microstructure in AZ21 and AS21 alloys withaluminum amount less than 3%. It was found that the intermetallic phases foundin the microstructure within the alloy had an effect on hardness, wear resistanceand machinability.
