preparation example Construction

[0026] 1. The preparation method of high-precision TA18 titanium alloy tube includes the following steps:

[0027] 1) Material preparation: take sponge titanium and add alloy treasure, said alloy treasure is 3AL2.5V, (that is, take 100kg of sponge titanium, add 3%AL and 2.5%V) and then press the two into electrode blocks;

[0028] 2) Smelting: put the electrode block into the vacuum consumable furnace, the vacuum degree in the furnace is less than 0.7MPa, and the temperature is heated to 1800℃-2000℃ for three times and then cast into titanium alloy ingots;

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

[0030] 4) Rolling titanium alloy tube blank:

[0031] a. Titanium alloy billet treatment: ultrasonic flaw detection is carried out on the surface of the titanium alloy billet. After the flaw detection is qualified, a center hole is punched at on...

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 preparation method of a high-precision TA18 titanium alloy tube. Background technique [0002] TA18 titanium alloy is a typical α+β two-phase titanium alloy. It contains 3% of α-stabilizing elements and 2.5% of β-stabilizing elements. The alloy has excellent comprehensive properties. With its good process plasticity and superplasticity, it can be formed. All kinds of parts are widely used in 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 is low, and the production cost is high, so it is necessary to improve. SUMMARY OF THE INVENTION [0003] The technical problem solved...
