Hot deformation behaviour of Mg-3Al-3Sn and Mg-3Al-3Sn-1 Zn Alloys: Role of Zn

Hot Deformation Behaviors of the Mg-3Sn-2Al-1Zn Alloy: Investigation on its Constitutive Equation, Processing Map, and Microstructure

“…In addition, the optimum hot working parameters for the fine-grained TZA822 alloy were determined to be 350 • C/0.01 s −1 and 350 • C/10 s −1 , at which point continuous DRX (CDRX) and discontinuous DRX (DDRX) were the main softening mechanisms [5]. In contrast to the Mg-8Sn based alloys with high Sn content, Mg-3Sn based alloys with a lower amount of Sn did not only decrease the density and solid solution temperature of alloy [7], but also exhibited higher tensile strength and elongation [8]. However, the knowledge on the hot deformation behaviors of the Mg-3Sn alloy in the literature mainly focuses on the Mg-3Sn-1Ca alloy [3,4].…”
