[0018] The present invention will be further described below in conjunction with the accompanying drawings and examples. The examples are used to illustrate the present invention, rather than limit the present invention. Simple improvements to the extrusion method of the present invention under the premise of the present invention are all within the scope of the present invention. The scope of protection required.
[0019] The composite extrusion die adopted by the composite extrusion processing method of magnesium alloy of the present invention is as follows: figure 1 As shown, the composite extrusion die includes a vertical extrusion channel A at the upper end, a vertical extrusion channel F at the lower end, and an S-shaped extrusion channel composed of three C-shaped channels B, D, and E in the middle. The extrusion die with compound extrusion deformation is used, and the magnesium alloy billet is extruded and deformed through the vertical cavity channel to the S-shaped ch...
