摘　　要：本研究在实验室中模拟工业电解槽实现直接电解生产含钛、硼、稀土多元微合金化铝合金。通过重熔后对其微观组织进行分析,发现在Ti含量相近时,电解法生产的Al-Ti-B晶粒细化效果比Al-Ti好,电解法生产的Al-Ti-B-La晶粒细化效果比Al-Ti-B好,而电解法生产的Al-Ti-La的晶粒细化效果没有Al-Ti好;并分析其细化机理。The productions of Al - Ti, Al - Ti - B, Al - Ti - La , Al - Ti - B - La by direct electrolysis are realized in the laboratory. Investigating the microstructures of the multi - alloys by remelting in the same Ti contents, the grain refinement efficiency of Al - Ti - B is finer than Al - Ti, the grain refinement efficiency of Al - Ti - B - La is finer than Al - Ti - B, however, the grain refinement efficiency of Al - Ti - La is bidder than Al - Ti; The author also analyzes the refinement theory of the titanium, boron, rare earth added by electrolysis.
