THE DEFORMATION BEHAVIOR OF AZ31 MAGNESIUM ALLOY AT ELEVATED TEMPERATURES
AZ31 magnesium alloy is considered as a promising alloy in various applications and industries. Furthermore, to design a proper hot working process (rolling, forging and extrusion), the assessment of hot working behaviour of the alloy is necessary. Accordingly, the hot deformation behaviour of AZ31 alloy was studied through hot compression testing method This was carried out in a wide range of ...

متن کاملCorrelation between the surface chemistry and the atmospheric corrosion of AZ31, AZ80 and AZ91D magnesium alloys
* Corresponding author. Tel: 34 1 3944348; Fax: 34 1 3944357 E-mail: [email protected] ABSTRACT X-ray photoelectron spectroscopy (XPS) was used in order to investigate the correlation between the surface chemistry and the atmospheric corrosion of AZ31, AZ80 and AZ91D magnesium alloys exposed to 98% relative humidity at 50oC. Commercially pure magnesium, used as the reference material, reveale...
متن کاملRapid solidification behavior of Zn-rich Zn–Ag peritectic alloys
Rapid solidification experiments, including laser remelting, melt-spinning and wedge casting, were carried out to investigate the rapid solidification behavior of Zn-rich Zn–Ag peritectic alloys containing up to 9.0 at% Ag. For comparison, Bridgman solidification experiments of the same alloys were also carried out for growth velocities ranging from 0.02 to 4.82 mm/s, which were lower than that...
متن کاملA cross-shear deformation for optimizing the strength and ductility of AZ31 magnesium alloys
Magnesium alloys have recently attracted great interest due their lightweight and high specific strength. However, because of their hexagonal close-packed structure, they have few active slip systems, resulting in poor ductility and high mechanical anisotropy at room temperature. In the present work, we used a cross-shear deformation imposed by a differential speed rolling (DSR) technique to im...
