1. a kind of less anisotropy ZK21 wrought magnesium alloys block materials preparation method, it is characterised in that:

  • Casting including alloyAnd hot-working, the casting mould of the alloy is rectangular water cooled copper mould, and mold compact dimensions are 150mm*150mm*150mm, mouldTool cooling water capacity is 300 ±

    10ml, and cooling water flow velocity is 3 ±

    0.5 liters/min;

    The hot processing temperature of the alloy be 300 ±

    5 DEG C, the hot-working preincubation time is 10 ±

    1 minutes, and thermal processing method is that small passage strains the forging of high strain rate three-dimensional, forgingEquipment is pneumatic hammer, and Repeat-heating, passage dependent variable are not 10 ±

    0.5% between passage, and rolling pass is 24 passages, the type of coolingIt is air-cooled.
