Embodiment Construction

[0025] The titanium alloy that is used to make cutter according to the present invention is made up of Ti, Al, V, Cr, Fe, Mo, W, Zr, O and Si, and the content of various compositions is Ti 1103Kg in the 1440Kg titanium alloy; Al 43.2 Kg; V 57.6Kg; Cr 72Kg; Fe 28.8Kg; Mo 100.8Kg; W 14.4Kg; Zr 14.4Kg;

[0026] The above-mentioned titanium alloy preparation method for making cutters is as follows:

[0027] The first step, mixing: take Ti 1103Kg; Al 43.2Kg; V 57.6Kg; Cr 72Kg; Fe 28.8Kg; Mo 100.8Kg; W 14.4Kg; Zr 14.4Kg; O 2.9Kg; Put it into the distributing machine for full mixing, the particle size of Ti particles is 0.83-25.4mm;

[0028] The second step, electrode production: put the alloy mixed in the first step into a 2500-ton vertical hydraulic press for extrusion, and the weight of each electrode is 45Kg;

[0029] Step 3: Smelting in a vacuum furnace: put the electrode made in the second step into a vacuum furnace for smelting. Three times of smelting will be carried out in...

Abstract

The invention discloses a titanium alloy for manufacturing a tool and a preparation method thereof. The titanium alloy for manufacturing a tool consists of the following components in percentage by weight: 76.6 percent of Ti, 3 percent of Al, 4 percent of V, 5 percent of Cr, 2 percent of Fe, 7 percent of Mo, 1 percent of W, 1 percent of Zr, 0.2 percent of O and 0.2 percent of Si. The preparation method of the titanium alloy comprises the following steps of: I, mixing; II, manufacturing an electrode; III, smelting in a vacuum furnace for three times; IV, cogging; and V, rolling. The titanium alloy has the beneficial effects that the HRC (Rockwell Hardness) value of the tool produced by using the titanium alloy disclosed by the invention is over 55, and the titanium alloy is light and non-magnetic, is low in production cost, and has a wide market prospect; and the production benefit of an enterprise can be increased greatly.

Description

technical field [0001] The invention relates to a titanium alloy and a preparation method, in particular to a titanium alloy used for making cutters and a preparation method. Background technique [0002] At present, in some industries, especially in the military industry, titanium alloys are basically used to make knives. However, the hardness HRC value of knives made of existing titanium alloys is generally less than 46. The hardness HRC value must be greater than 50 to meet the requirements. In some environments (such as: in the process of diving and other related operations), the knives made of existing titanium alloys cannot meet the requirements. In order to ensure that the knives used in military and other related industries Therefore, it is urgent to develop a titanium alloy for cutting tools. Contents of the invention [0003] The purpose of the present invention is to provide a titanium alloy for making a knife and a preparation method thereof in order to solve ...
