Claim:
1. A method of manufacturing an alloy sputtering target, the method comprising: preparing an amorphous alloy or a nanocrystalline alloy having glass-forming ability and comprising three or more metallic elements; and heat-pressurizing the amorphous alloy or the nanocrystalline alloy in a temperature range of a crystallization initiation temperature of the amorphous alloy or the nanocrystalline alloy or higher but lower than a melting temperature thereof to manufacture a crystalline alloy having an average grain size of 0.1 μm to 5 μm, wherein the amorphous alloy or the nanocrystalline alloy comprises 5 at % to 20 at % of aluminum (Al), 15 at % to 35 at % of any one or more elements selected from copper (Cu) and nickel (Ni), and the remainder being zirconium (Zr).
