    摘要： A method of making high melting point alloys. The reactive and non-reactive charge materials are separately refined as initial alloys, generally as an alloy of a base element selected from the iron group of the Periodic Table, such as nickel, and at least one metallic element other than the base element. At least one first initial alloy and at least one second initial alloy are provided. The metallic elements other than the base element in the first initial alloys are relatively non-reactive in the molten state, whereas the metallic elements in the second initial alloys are relatively reactive in the molten state. Amounts of the first and second initial alloys are selected to yield a predetermined composition of the high melting point alloy upon melting. The selected amounts are melted to form a molten mixture having the predetermined composition, and then the molten mixture is solidified.
