Problems solved by technology

At present, most titanium alloy master alloys use binary alloys and ternary alloys. The master alloys produced with simple metals as raw materials have complex production processes and high costs. In order to meet the performance requirements during use, several binary alloys or ternary alloys need to be added. Therefore, it is easy to cause the instability of product performance and bring difficulties to the intermediate process of producing titanium alloy.

[0020]

[0021] 3. Put the raw materials into the mixing machine for mixing. Mixing requirements: each raw material must be fully mixed evenly to ensure sufficient contact between raw materials.

[0022] 4. Finally, furnace is installed for smelting, and the furnace temperature is 30-60°C. After 24 hours, it was released from the furnace, and the alloy ingot was taken out to obtain the product. Chemical analysis was carried out on the alloy components taken out, and the following results were obtained.

Abstract

The invention relates to an aluminium-vanadium-tin-copper-iron intermediate alloy and a preparation method thereof, and relates to an aluminium-vanadium-tin (aluminium-vanadium-tin-based) intermediate alloy for the preparation of the titanium alloy and a preparation method thereof. The intermediate alloy is characterized in that the alloy comprises the following components by weight percent: 36.0%-42.0% of V, 11.0%-15.0% of Sn, 4.0%-6.0% of Fe, 4.0%-6.0% of Cu and the balance Al. The preparation process adopts the metallothermics. The aluminium-vanadium-tin-copper-iron alloy is a metal compound using vanadium, tin, copper, iron and the like as main components and has the characteristics of high brittleness and easiness in breakage, thus the production process of the titanium alloy can be shortened and the operations of the production process of the titanium alloy are easier. The aluminium-vanadium-tin-copper-iron alloy uses oxides as raw materials and has low cost, the smelting process is stable, the formed state of the alloy is good; and alloying is uniform, the alloy is added in spongy titanium and aluminium shot in an intermediate alloy manner, and the degree of the segregationof the titanium alloy is reduced.

Description

technical field [0001] An aluminum-vanadium-tin-copper-iron master alloy and a preparation method thereof, relating to an aluminum-vanadium-tin (aluminum-vanadium-tin-based) master alloy used for preparing titanium alloys and a preparation method thereof. Background technique [0002] Titanium alloys are widely used in military industry, aerospace industry and civil industry, and master alloys are important raw materials for the production of titanium alloys. At present, most titanium alloy master alloys use binary alloys and ternary alloys. The master alloys produced with simple metals as raw materials have complex production processes and high costs. In order to meet the performance requirements during use, several binary alloys or ternary alloys need to be added. Therefore, it is easy to cause the instability of product performance and bring difficulties to the intermediate process of producing titanium alloy.
