[0073] The embodiment of the present invention provides a processing method of magnesium alloy sheet, such as figure 1 As shown, the method includes:
[0074] Step 101: Add a first preset amount of nano-scale silicon carbide with a target particle size to a solution of magnesium alloy raw materials, and stir uniformly to obtain a target mixed solution.
[0075] Among them, by controlling the total amount of nano-scale silicon carbide added to the magnesium alloy, the strength of the magnesium alloy sheet obtained by the final processing can be changed. The first preset amount added in the embodiment of the present invention is 0.1% to 5% of the mass of the magnesium alloy raw material, which can enable the magnesium alloy sheet obtained by final processing to achieve higher strength.
[0076] In addition, preferably, the target particle size is 50 nm to 70 nm. Among them, nano-scale silicon carbide with an average particle size of 50 nanometers to 70 nanometers can already be mass-p...

[0108] The embodiment of the present invention provides a magnesium alloy sheet, such as Figure 2~4 As shown, the magnesium alloy sheet includes: a magnesium alloy substrate 1, the magnesium alloy substrate 1 including magnesium alloy crystals and nano-scale silicon carbide 4, and the nano-scale silicon carbide 4 is dispersed among the magnesium alloy crystals;
[0109] The graphene film 2 covering the surface of the magnesium alloy substrate 1.
[0110] Among them, the nano-scale silicon carbide 4 dispersed among the magnesium alloy crystals can play a role of dispersion strengthening and improve the strength of the magnesium alloy sheet of the embodiment of the present invention. From Figure 5 It can be seen from the curve shown that the yield strength and tensile strength of the strengthened magnesium alloy are greatly increased, the tensile strength is as high as 400MPa, the forming performance is also greatly increased, and the elongation rate is as high as 15%. Further, th...
