Abstract:
1. A method for producing an aluminum-zirconium-titanium-carbon intermediate alloy, characterized in that the aluminum-zirconium-titanium-carbon intermediate alloy has a chemical composition of 0.01% to 10% Zr, 0.01% to 10% Ti, 0.01% to 0.3% C, and Al in balance, based on weight percentage; the producing method comprising the steps of: a. preparing commercially pure aluminum, zirconium metal, titanium metal, and graphite material according to the weight percentages of the aluminum-zirconium-titanium-carbon intermediate alloy; the graphite is graphite powder having an average particle size of 0.074 mm to 1 mm; and the graphite powder is subjected to the following treatments: being added to an aqueous solution of KF, NaF, K b. melting the commercially pure aluminum and keeping it at 700° C. to 900° C. to provide aluminum liquid, in which a prepared zirconium, titanium and the treated graphite powder are added and melted to provide an alloy solution; and c. keeping the alloys solution at 700° C. to 900° C. under mechanical or electromagnetic agitation and performing casting.
