Effect of Pb and Sn Additions on the Ductility of Cast AZ61 Mg Alloy
AZ61 alloy is an important magnesium (Mg) alloy which can be rolled at elevated temperature. However, the insufficient ductility of as-extruded alloys limits their design and applications. Pb or Pb+Sn additions lead to a high ductility (~18% at room temperature) and good tensile strength (~250 MPa). This paper discusses the mechanism of property enhancement and the influence of Pb addition on the solidification process of AZ61 alloy.
