Embodiment Construction

[0032] As mentioned in the background art, the preparation of the high-purity aluminum-copper-tungsten alloy formed in the prior art is quite difficult.

[0033] A method for forming an aluminum-copper-tungsten alloy, comprising: providing molten aluminum, tungsten-aluminum alloy, and a copper source; placing the tungsten-aluminum alloy in the molten aluminum; placing the copper source in the molten aluminum; After the tungsten aluminum alloy and copper source are placed in the molten aluminum, heat preservation treatment is carried out to form a molten aluminum-copper-tungsten alloy; the molten aluminum-copper-tungsten alloy is ingot-cast to form an aluminum-copper-tungsten alloy.

[0034] Since the melting point of tungsten is very high, about 3410 degrees Celsius, the melting point of aluminum is only 660 degrees Celsius, and the melting points of tungsten and aluminum are quite different, so it is difficult for tungsten to melt into the molten aluminum. Therefore, it is ne...

Abstract

A forming method of an aluminum-copper-tungsten alloy comprises the steps that an aluminum melting solution, tungsten powder and a copper source are provided; the tungsten powder is placed in the aluminum melting solution; the copper source is placed in the aluminum melting solution; after the tungsten powder and the copper source are placed in the aluminum melting solution, first heat-insulatingtreatment is conducted to form an aluminum-copper-tungsten alloy melting solution; and the aluminum-copper-tungsten alloy melting solution is subjected to ingot casting to form the aluminum-copper-tungsten alloy. According to the forming method, the process difficulty of aluminum-copper-tungsten alloy forming can be reduced, and the use purity requirement of the aluminum-copper-tungsten alloy is met.

Description

technical field [0001] The invention relates to the field of alloy manufacturing, in particular to a method for forming an aluminum-copper-tungsten alloy. Background technique [0002] An alloy is a substance with metallic properties composed of two or more metals or nonmetals. According to the number of constituent elements, alloys are classified into binary alloys, ternary alloys, and multielement alloys. [0003] Aluminum-copper-tungsten alloy is an important ternary alloy. High-purity aluminum-copper-tungsten alloys can be used in many fields, such as: high-purity aluminum-copper-tungsten alloys are used to prepare high-purity aluminum sputtering targets containing copper and tungsten. [0004] However, the preparation of the high-purity aluminum-copper-tungsten alloy formed in the prior art is relatively difficult. Contents of the invention [0005] The problem to be solved by the present invention is to provide a method for forming an aluminum-copper-tungsten allo...
