1. the preparation method of a medical magnesium base alloy material, it is characterised in that the preparation side of described medical magnesium base alloy materialMethod comprises the following steps:

  • (1) take respectively metal powder material, by weight percentage take Ti be 3.2wt%-5.6wt%, W be that 0.3wt%-0.8wt%, V are0.2wt%-0.7wt%, Ni be 1.2wt%-3.4wt%, Cr be 0.3wt%-1.1wt%, Ag be that 0.2wt%-0.6wt%, Sc are0.3wt%-0.8wt%, Nb are 0.2wt%-0.8wt%, surplus is Mg, by above-mentioned metal powder material high-speed mixer machineryMixing, mixing is to metal dust mix homogeneously;

    (2) after mix homogeneously, metal powder material being thrown to by high-temperature vacuum smelting furnace, in vacuum melting furnace, pressure is300Pa, rises to 680 DEG C by vacuum melting in-furnace temperature from room temperature, melting 2h after temperature stabilization;

    (3) Raise vacuum melting in-furnace temperature is 940-970 DEG C, molten 3h after temperature stabilization;

    (4) Raise vacuum melting in-furnace temperature is 1135-1175 DEG C, melting 3h after temperature stabilization;

    (5) reduce vacuum melting in-furnace temperature and be 550-580 DEG C, be incubated 2h;

    (6) again vacuum melting in-furnace temperature is down to room temperature, for medical magnesium base alloy material.
