Problems solved by technology

[0002] At present, some special industries, especially in the military industry, basically use titanium alloys for the production of knives. The hardness HRC value of the knives made of existing titanium alloys is generally less than 46, and the hardness HRC value of the knives used in some operations is higher than 46. If it is greater than 50, the cutting tools made of existing titanium alloys in some environments cannot meet the requirements. Chinese invention patent CN102851542A discloses a titanium alloy for making cutting tools and its preparation method. Although the method increases the HRC value To 55-57, but adding 4% metal vanadium, resulting in high prices of titanium alloys

preparation example Construction

[0017] The preparation method of titanium alloy for high-performance cutter of the present invention comprises the following steps:

[0018] A. Weigh each element powder, high-purity aluminum ingot and titanium sponge with a purity of more than 99.7% according to the formula;

[0019] B. Melting each raw material with a vacuum consumable electrode arc melting method to obtain a high-temperature titanium alloy ingot;

[0020] C. Heat preservation treatment at 650-700°C for 2-3 hours, then heat preservation treatment at 400-420°C for 2-3 hours, and then cool naturally.

Abstract

The invention discloses a titanium alloy used for a high performance cutter. The titanium alloy includes, by weight, the following components: 1.0-1.5% of Al, 0.1-0.3% of B, 0.5-1.0% of W, 0.8-1.2% ofCo, 0.2-0.5% of Fe, 0.6-1.0% of Cr, with the balance being Ti and unavoidable impurities. A hardness HRC value of the titanium alloy is increased to 60-62; vanadium is completely replaced by cheap elements of chromium, iron, cobalt, boron and tungsten, so that the cost is greatly reduced, and the cost performance is very excellent; and a preparation method of the titanium alloy is simple, the cost is significantly lower than cost of market products, and the titanium alloy has a very good market prospect.

Description

technical field [0001] The invention relates to the technical field of titanium alloy materials, in particular to a titanium alloy for high-performance cutting tools. Background technique [0002] At present, some special industries, especially in the military industry, basically use titanium alloys for the production of knives. The hardness HRC value of the knives made of existing titanium alloys is generally less than 46, and the hardness HRC value of the knives used in some operations is higher than 46. If it is greater than 50, the cutting tools made of existing titanium alloys in some environments cannot meet the requirements. Chinese invention patent CN102851542A discloses a titanium alloy for making cutting tools and its preparation method. Although this method increases the HRC value To 55-57, but adding 4% metal vanadium, resulting in high prices of titanium alloys. [0003] Therefore, it is necessary to develop a high-performance titanium alloy for cutting tools, ...
