Embodiment 1
[0017] The weight percent alloy composition of the aluminum-vanadium-chromium-iron-titanium master alloy is: V: 26.0%%, Cr: 20.0%, Fe: 6%, Ti: 6%, and Al is the balance. The five-element alloy is used as an intermediate alloy, and is added to sponge titanium and aluminum beans in the form of an alloy package. When using a vacuum consumable furnace to smelt titanium alloys, it is easy to control the magnitude of the current because of the uniform composition of the ingot, which facilitates the preparation of titanium alloys. The degree of alloy segregation is low.
Embodiment 2
[0019] The weight percent alloy composition of the aluminum vanadium chromium iron titanium master alloy is: V: 32.0%, Cr: 25.0%, Fe: 10%, Ti: 10%, and Al is the balance. The five-element alloy is used as an intermediate alloy, and is added to sponge titanium and aluminum beans in the form of an alloy package. When using a vacuum consumable furnace to smelt titanium alloys, it is easy to control the magnitude of the current because of the uniform composition of the ingot, which facilitates the preparation of titanium alloys. The degree of alloy segregation is low.
Embodiment 3
[0021] The weight percent alloy composition of aluminum vanadium chromium iron titanium master alloy is: V: 30.0%, Cr: 22.0%%, Fe: 8%8, Ti: 8%, Al is the balance. The five-element alloy is used as an intermediate alloy, and is added to sponge titanium and aluminum beans in the form of an alloy package. When using a vacuum consumable furnace to smelt titanium alloys, it is easy to control the magnitude of the current because of the uniform composition of the ingot, which facilitates the preparation of titanium alloys. The degree of alloy segregation is low.
