Abstract

The invention discloses an aluminum-titanium-molybdenum intermediate alloy. The alloy comprises, by mass, 50.0-55.0% of molybdenum, 1.0-5.0% of titanium and the balance being aluminum. The preparationmethod of the aluminum-titanium-molybdenum intermediate alloy comprises the following steps of uniformly mixing aluminum, molybdenum trioxide and calcium fluoride, placing a mixture into a reaction crucible for aluminothermic reaction to obtain an alloy liquid, and cooling the alloy liquid to obtain an aluminum-molybdenum intermediate alloy; and uniformly mixing the aluminum-molybdenum intermediate alloy and titanium sponge, placing a mixture into a smelting crucible, performing vacuumizing, argon filling and smelting, performing refining after materials are completely melted to obtain an alloy liquid, and performing casting and cooling to obtain the aluminum-titanium-molybdenum intermediate alloy. According to the aluminum-titanium-molybdenum intermediate alloy and the preparation methodthereof, the aluminum-titanium-molybdenum intermediate alloy is uniform in component, small in segregation and low in impurity content.
