Magnesium alloy AZ80A is a Mg-Al-Zn alloy in which the main alloying element is Al. The strength and specific strength of AZ80 wrought magnesium alloy and other materials, AZ80 wrought magnesium alloy has considerable advantages compared with other materials in comprehensive mechanical properties.

Elongation after break: refers to the ratio of the length of the material to the original gauge length after the material is broken.

Yield strength: refers to the force at a point in the plastic deformation zone of a material after being subjected to a force greater than its elastic deformation force.

Tensile strength: refers to the ability of a material to resist deformation. These data are important indicators for evaluating the mechanical properties of materials.

The tensile strength ob, yield strength os and elongation after fracture of AZ80 magnesium alloy extruded at different temperatures were 3 at extrusion ratio of 3. With the increase of temperature, the tensile strength of the material gradually increased, and gradually decreased after 350 °C, and the tensile strength was 320, 340, 325 and 325 MPa, respectively. Compared with the original state, the tensile strength has been improved with the change of extrusion temperature. The yield strength of the material increases gradually with the increase of temperature. The yield strengths were 265, 295, 295 and 310 MPa, respectively.

Like the yield strength, the elongation after fracture first increases and then decreases. Overall, when the extrusion temperature is 350 ℃, the comprehensive performance is the best. Mechanical properties of different extrusion ratios

Tensile strength ob, yield strength os and elongation after fracture of AZ80 magnesium alloy extruded at different extrusion ratios at extrusion temperature of 400 °C.

With the increase of extrusion ratio, the tensile strength gradually increased, which were 325, 340 and 355MPa, respectively. Compared with the original state, the tensile strength has been improved with the change of extrusion temperature. The yield strength decreased gradually with the increase of extrusion ratio, and were 310, 92, and 91 MPa, respectively. The elongation after fracture, like the yield strength, first increases and then decreases with the increase of the compression ratio.
