preparation example Construction

[0026] 1, TA18 titanium alloy tube preparation method, comprises the following steps:

[0027] 1) Prepare materials: take titanium sponge and add alloy package, the alloy treasure is 3AL2.5V, (i.e. take 100kg titanium sponge, add 3% AL and 2.5% V) and then press the two into an electrode block;

[0028] 2) Melting: put the electrode block into a vacuum consumable furnace, and the vacuum degree in the furnace is less than 0.7MPa, and the temperature is raised to 1800°C-2000°C for three times of melting, and then cast into titanium alloy ingots;

[0029] 3) Put the titanium alloy ingot into a resistance furnace and heat it to 850°C-900°C, keep it warm for 1-3 hours and pierce it several times to form a titanium alloy billet;

[0030] 4) Rolled titanium alloy tube billet:

[0031] a. Titanium alloy billet treatment: Ultrasonic flaw detection is performed on the surface of the titanium alloy billet. After passing the flaw detection, a center hole is punched at one end of the tita...

Abstract

The invention provides a high-accuracy TA18 titanium alloy pipe preparation method comprising the steps of preparing material, melting, putting a titanium alloy ingot into a resistance furnace to heat until temperature reaches up to 850 DEG C to 900 DEG C, forming a titanium alloy sheared billet after preserving heat for one to three hours and mounding and drawing for several times, rolling a titanium alloy pipe blank, rolling roughly, rolling precisely, and annealing. A titanium alloy pipe produced by utilizing the high-accuracy TA18 titanium alloy pipe preparation method is high in finished product rate, low in production cost, good in fineness which can reach h6, reasonable in crystal structure, and pretty high in practical value.

Description

technical field [0001] The invention belongs to the technical field of titanium alloy processing, and in particular relates to a method for preparing a TA18 titanium alloy pipe. Background technique [0002] TA18 titanium alloy is a typical α+β two-phase titanium alloy, which contains 3% of α-stable elements and 2.5% of β-stable elements. Various parts are widely used in the aviation industry, medical equipment, sporting goods, sports equipment, etc., but the production of TA18 titanium alloy pipes is difficult because of the large deformation resistance and strong work hardening. TA18 titanium alloy pipes produced by traditional methods It is easy to crack, the surface finish is poor, the yield rate is low, and the production cost is high, so it is necessary to improve. Contents of the invention [0003] The technical problem solved by the present invention is to provide a preparation method of TA18 titanium alloy pipe, which solves the problems of low yield, high produc...
