摘要
The present invention relates to a preparation method of a lithium-containing magnesium/aluminum matrix composite. The preparation method is performed according to the following steps: (1) preparing magnesium ingots or aluminum ingots, preparing lithium metal, and preparing flux and reinforcements; (2) heating the flux to prepare flux melt, and adding the reinforcements to the flux melt to prepare a liquid-solid mixture; (3) pouring the liquid-solid mixture in a normal-temperature crucible, and performing cooling to obtain a precursor; (4) preheating a crucible, adding raw materials, and performing melting to form a raw material me (5) controlling a temperature of the raw material melt to 973-993K, adding the lithium metal, performing stirring, adding the precursor, performing stirring and mixing, raising temperature to 993-1013K, and performing standing; and (6) scumming operation should be carried out, and performing temperature casting on composite melt.
