AZ80
AZ80 magnesium alloy is a high-strength magnesium alloy mainly used for extrusion and simple designed forgings. It consists of the following elements: magnesium (Mg), aluminum (Al), zinc (Zn), and manganese (Mn). TThe chemical composition (mass fraction %) of the AZ80 magnesium alloy:
The AZ80 alloy possesses excellent mechanical properties, including:
Tensile strength: 380 MPa
Yield strength (0.200% strain): 275 MPa
Shear strength: 165 MPa
Compressive yield strength (0.2% offset): 240 MPa
Elastic modulus: 44.8 GPa
Poisson's ratio: 0.35
Elongation at fracture: 7%
Additionally, the AZ80 alloy also exhibits good thermal properties such as thermal expansion coefficient and thermal conductivity.
The achievement of microstructure refinement in the novel weak texture magnesium alloy AZ80 through technological advancements signifies a significant breakthrough in overcoming the challenge of refining eutectic phases in the high-alloy AZ80 system, thereby promoting the development of magnesium alloys. the results of the tensile test conducted on specimens of the refined eutectic phase in AZ80 magnesium alloy:
AZ80 magnesium alloy is a high-strength and uniquely quenching and aging-strengthened alloy within the Mg-Al alloy family. It can be used in automotive components such as wheel hubs, seat frames, and steering wheels.
Using the forging process for magnesium alloy wheel hubs results in higher strength, better toughness, and improved damage resistance. Due to its microstructure without pores, it offers high pressure sealing performance compared to aluminum alloy wheel hubs. It has the advantages of light weight, safety, comfort, and energy efficiency.
