Embodiment 1
[0027] Example 1 Stress-assisted phase diffusion rolling method of high volume fraction second-phase magnesium alloy
[0028] 1) Stress-assisted phase diffusion: put the cast-rolled ATZ421 magnesium alloy billet into the heating box, and then perform one pass of pre-deformation rolling at 250 degrees Celsius for 10 minutes, with a reduction of 8%; then the pre-deformed magnesium The alloy is placed in a heating furnace, heated to 425 degrees Celsius for 150 minutes under the protection of argon, and the second phase is diffused by heat treatment;
[0029] 2) High-temperature rolling: the slab after the heat treatment in step (1) is rolled through more than 8 passes, the reduction of each pass is 10%, and the temperature is kept at 330 degrees Celsius for 15 minutes between each pass, and rolled into a thin plate. The total reduction is greater than 70%;
[0030] 3) Recrystallization treatment: place the rolled sample in a heating furnace, and perform annealing heat treatment ...

[0031] Example 2 Stress-assisted phase diffusion rolling method of high volume fraction second-phase magnesium alloy
[0032] 1) Stress-assisted phase diffusion: put the cast-rolled ATZ421 magnesium alloy billet into the heating box, and carry out 2 passes of pre-deformation rolling after holding it for 10 minutes at 280 degrees Celsius, and the reduction in each pass is 10%; then pre-deformed The final magnesium alloy is placed in a heating furnace, heated to 400 degrees Celsius for 180 minutes under the protection of argon, and the second phase is diffused by heat treatment;
[0033] 2) High-temperature rolling: the slab after the heat treatment in step (1) is rolled for more than 5 passes, the reduction of each pass is 15%, and the temperature is kept at 350 degrees Celsius for 10 minutes between each pass, and rolled into a thin plate. The total reduction is greater than 70%;
[0034] 3) Recrystallization treatment: place the rolled sample in a heating furnace, and perfor...
