Example Embodiment
[0050] Example one
[0051] The cold pressing die 100 and the extrusion die 200 are used in the process of preparing the AZ31-RE wrought magnesium alloy provided in this embodiment, see figure 1 with figure 2 . Among them, the cold pressing die 100 includes a cold pressing punch 101, a cold pressing inner sleeve 102, a cold pressing sleeve 103, and a pressure pad 104; the extrusion die 200 includes an extrusion punch 201, an extrusion inner sleeve 202, and an extrusion die. Sleeve 203 and mold 204. The diameter of the cold press punch 101 is 4 mm smaller than the diameter of the extrusion punch 201, and the inner diameter of the cold press inner sleeve 102 is 4 mm smaller than the inner diameter of the extrusion inner sleeve 202.
[0052] The method for preparing AZ31-RE wrought magnesium alloy provided in this embodiment includes the following steps:
[0053] a. Machining of AZ31 magnesium alloy and Mg-RE master alloy: Use a lathe to process AZ31 magnesium alloy into the first c...
Example Embodiment
[0062] Example two
[0063] In the method for preparing the AZ31-RE wrought magnesium alloy provided in this embodiment, the processing size of the AZ31 magnesium alloy in step a is different from that in the first embodiment, and the other steps are the same as the embodiment.
