title = "Extruded Mg-Sn-Al-Zn alloys with superior tensile properties",
abstract = "This study investigated the microstructure and tensile properties of three indirectly extruded Mg-Sn-Al-Zn alloys: Mg-11Sn-1Al-1Zn (TAZ1111), Mg-8Sn-4Al-1Zn (TAZ841), and Mg-8Sn-1Al-4Zn (TAZ814). The investigation results revealed that in all the alloys, Mg2Sn particles formed during solidification were not fully dissolved by homogenization treatment. These undissolved particles enhanced the dynamic recrystallization behavior through a particle-stimulated nucleation phenomenon. As a result, all the extruded alloys exhibited a fully dynamically recrystallized microstructure. The tensile yield strength (TYS) of the extruded alloys was in the following order: TAZ1111 > TAZ841 > TAZ814. In contrast, the elongation of the alloys was in the opposite order: TAZ814 > TAZ841 > TAZ1111. The highest TYS of the TAZ1111 alloy was attributed mainly to the smaller grain size and more abundant Mg2Sn precipitates resulting from a higher Sn content. However, the ultimate tensile strengths of all the extruded alloys were nearly the same because the Al or Zn atoms dissolved in the TAZ841 and TAZ814 alloys improved the strain hardening rate during plastic deformation.",
