Characteristics and precautions of titanium alloy tube

Generally, the environment for titanium tube manufacturers to repair and weld titanium tubes cannot have flowing air, and other aspects are the same as repair welding in a welding box. But special attention should be paid to:

1. The repair welding area should not be too large, the flow of nitrogen gas should be larger during the repair welding process, and the gas cannot be stopped in the middle;

2. After repair welding, nitrogen protection should be continued until the area cools down;

3. For some special castings, such as complex thin-walled castings, in order to prevent oxidation on the back of the repair welding area, argon can be blown to the back until the casting cools down;

4. It is required that repair welding operators have a high technical level.

In order to obtain titanium tube castings with good repair welding quality, the following points should be paid attention to during the repair welding process:

1. The surface of the repaired castings must be cleaned and dried, and the castings are not allowed to be touched directly with hands before they are put into the welding box.

2. In the process of repairing grade 5 titanium sheet, strictly prevent the short circuit between the tungsten electrode and the repaired part, which will cause the tungsten electrode to break and cause tungsten inclusions in the solder joints.

3. When the area and depth of the repair welding area are relatively large, the remote layer welding should be divided into multiple times, and the next layer of welding can only be performed after the previous layer of welding layer is completely cooled. It is absolutely not allowed to weld in one time. Prevent casting deformation.

4. When the repair welding is about to end, the current should be gradually reduced to reduce the melting zone. Therefore, it is recommended to use pulse current to prevent sudden arc breaking and cracks.

5. After repair welding, the casting should be cooled in the box for a period of time before taking out the casting to prevent cracks or deformation in the welding area of ​​the casting caused by rapid cooling; the cooling time depends on the wall thickness of the casting, usually 15-30mm.

6. After the repair welding of titanium tube castings, it should be annealed or hot isostatic pressed in time, and it should not be left for too long, usually no more than 5 days.

7. The number of welding repairs cannot exceed the provisions of the relevant technical documents.

Titanium rod, titanium plate, burr treatment method of titanium workpiece

The method of this kind of mechanical treatment is: to bury the Titanium Coil Tube in a lot of abrasives, add some grinding and polishing compounds dissolved in water, use the principle of vibration to mix the abrasives and materials, and continuously wash the workpiece, the surface, and edges of the workpiece Angles, etc. are ground by abrasives and then polished. This technique can be used for deburring, chamfering, derusting, descaling, flattening, and fine polishing for metal parts of various sizes and shapes.

Abrasives can be alumina (including fused, sintered, or natural), corundum, plastic, quartz, ceramics, etc., which can be single or mixed. The shapes of these abrasives can be made into diagonal, cylindrical, diamond-shaped, etc. The reason why pre-shaped abrasives are made first is that they are more economical and wear faster than random-shaped and natural-shaped materials. According to the shape and size of the workpiece, choose abrasives of different shapes and sizes. Abrasives for tumbling include pumice, quartz, granite horns, shells, iron filings, and ceramic fragments. The size of the abrasive grain should be larger or smaller than each hole of the part. The amount of content in the drum is also an important factor affecting the quality of the surface of the parts. The amount of people in the drum is usually 70% of the volume of the drum. The solution in the drum should be added to account for about 95% of the volume of the drum (note: when adding the acidic solution to the drum, add enough water first, and then add acid to prevent parts from corroding during the rolling process, due to the increase in time , the concentration of the built-in solution gradually decreases, and even loses its effect.

Trimming process requirements and methods for titanium alloy forging

In the application of various titanium alloy products, forgings are mostly used in occasions requiring high strength, high toughness, and high reliability, such as gas turbine compressor discs and medical artificial bones. Therefore, not only high dimensional accuracy is required for forgings, but also materials with excellent characteristics and high stability are required. For this reason, in the manufacturing process of forge titanium ring, the characteristics of titanium alloys should be fully utilized to obtain high-quality forgings. Titanium alloy metal is difficult to forge and is prone to cracks. Therefore, it is very important to properly control the forging temperature and plastic deformation in the production of titanium alloy forgings.

Trimming of titanium alloy forgings must meet the following requirements:

1. The incision is smooth, and the metal on the blank must not collapse.

2. There must be no cracks in the part adjacent to the incision surface of the blank, and there must be no uneven grain size caused by uneven trimming deformation.

3. No indentation of the punch shall be left on the trimmed blank, and the shape of the punch and the part shall be exactly the same.

The edge can be trimmed with a milling machine or cut with a band saw and a specially designed friction plate. For large forgings and thick burrs, regardless of the size or batch size of the parts, it is inconvenient to thermally trim the edges, and flame cutting is an effective method. Oxygen gas, plasma, and other techniques can be used to successfully and economically cut burrs of 50 mm or thicker. After flame cutting, heat treatment should be carried out so that the heat-affected zone can be machined. For larger batches of medium and small titanium alloy forgings, the edge is usually trimmed with a die on a crank press, and the edge trimming is carried out at 600-800°C. If straightening must be carried out immediately after trimming, the trimming temperature should be close to the upper limit. Titanium alloys are rarely trimmed with a mold in a cold state because the burrs are very hard and brittle, which may easily cause uneven incisions, and even cause the risk of metal cracking and rapid debris splashing; for some alloys with a high degree of alloying, cold trimming It will cause cracks on the shear surface, and the cracks will extend into the metal from time to time.

Structural Titanium Alloy

Low-strength titanium alloys are mainly used for corrosion-resistant titanium alloys. Other titanium alloys are used for structural parts called structural alloys. In practical applications, structural titanium alloys are divided into: ordinary-strength titanium alloys, medium-strength titanium alloys, and high-strength titanium alloys. alloy. Ordinary strength titanium alloy: due to its good processing and formability and weldability, it is mostly used in the manufacture of various aviation sheet parts and civil products such as hydraulic pipes and bicycles. Medium-strength grade 5 titanium round bar: The typical alloy is TC4, which is mostly used in high-tech industries such as aerospace and rocket launch. High-strength titanium alloys: generally used to replace high-strength structural steel commonly used in aircraft structures.

What are the excellent properties of titanium metal?

1. Low density and high specific strength. The density of titanium metal is 4.51g/cm3, which is higher than that of aluminum and lower than that of steel, copper, and nickel, but its specific strength ranks first among metals. 2. Corrosion resistance. Titanium is a very active metal, its equilibrium potential is very low, and its thermodynamic corrosion tendency in the medium is large. But in fact, titanium is very stable in many media, such as titanium is corrosion-resistant in oxidizing, neutral and weakly reducing media.

This is because titanium and oxygen have a great affinity. In the air or in an oxygen-containing medium, a dense, strong, and inert oxide film is formed on the surface of titanium, which protects the titanium substrate from corrosion. Self-healing or regenerating quickly even due to mechanical wear. This indicates that titanium is a metal with a strong tendency to passivation. The titanium oxide film always maintains this characteristic when the medium temperature is below 315℃.​​

In order to improve the corrosion resistance of titanium, surface treatment technologies such as oxidation, electroplating, plasma spraying, ion nitridation, ion implantation, and laser treatment have been developed to enhance the protection of the titanium oxide film and obtain the desired corrosion resistance. Effect. A series of corrosion-resistant titanium alloys such as titanium-molybdenum, titanium-palladium, titanium-molybdenum-nickel, etc. have been developed for the needs of metal materials in the production of sulfuric acid, hydrochloric acid, methylamine solution, high-temperature wet chlorine gas, and high-temperature chloride.

3. Good heat resistance. The new Grade 1 Pure Titanium Plate can be used for a long time at a temperature of 600 ℃ or higher. Fourth, the low-temperature performance is good. Low-temperature titanium alloys represented by titanium alloys TA7 (Ti-5Al-2.5Sn), TC4 (Ti-6Al-4V), and Ti-2.5Zr-1.5Mo, the strength increases with the decrease of temperature, but the plasticity does not change. big. It maintains good ductility and toughness at a low temperature of -196-253 °C and avoids the cold brittleness of metals. It is an ideal material for low-temperature containers, storage tanks, and other equipment.

5. Strong anti-dumping performance. When Grade 9 Ti-3Al-2.5V Titanium Plate is subjected to mechanical vibration and electrical vibration, its own vibration attenuation time is very long compared with steel and copper metals. Using this property of titanium, it can be used as a tuning fork, a vibration element of a medical ultrasonic mill, and a vibration film of an audio speaker.

Properties of Ti45Nb Titanium Alloy for Aviation Standard Parts

The new generation of aircraft continues to develop in the direction of high weight reduction, long life and low cost, which greatly increases the amount of advanced composite materials and titanium alloy materials. Ti45Nb titanium alloy can be used as a connector for titanium alloys and composite materials. More and more attention- 2-50. During the "Eleventh Five-Year Plan" period in my country, the application research of T45Nb titanium alloy has been carried out, and Grade 36 Ti45Nb Titanium Wire has been determined as the main rivet material for composite material connection.

Ti45Nb titanium alloy belongs to β-type titanium alloy, which has the characteristics of high plasticity (elongation rate can reach more than 20%, section shrinkage rate can reach 60%~80%), corrosion resistance, excellent cold working performance, etc., and shear strength, tensile strength Higher than pure titanium, the deformation resistance is lower than pure titanium.

A lot of research work has been done on Ti45Nb titanium alloy abroad, the technology is relatively mature, and it was included in the AMS 4982 specification in 1974. In aerospace products, it has completely replaced the pure titanium rivet material, especially the alloy is made with Ti6A14V alloy. The bimetal rivet not only improves the shearing degree of the rivet, but also enables cold riveting. This kind of rivet with excellent comprehensive performance has been widely used in Airbus and Boeing aircraft.

(1) Processed organization. Since the processed Ti45Nb titanium alloy wire is deformed by cold drawing, there are a lot of slip bands at the grain boundary after cold drawing, and the grains are fibrous along the drawing direction.

(2) The annealed state structure. The microstructure of Ti45Nb titanium alloy wire has been recovered and recrystallized after annealing. The grains are equiaxed and the grain boundaries are clear.

Matters needing attention in titanium alloy processing

Pressure machining of titanium alloys is more similar to steel machining than to non-ferrous metals and alloys. Many process parameters of titanium alloys in forging, volume stamping, and sheet stamping are close to those in steel processing. But there are some important features that must be paid attention to when pressing working titanium and titanium alloys.

While it is generally believed that the hexagonal lattices contained in titanium and titanium alloys are less ductile when deformed, various press-working methods used for other structural metals are also applicable to Titanium Alloy Seamless Rectangular Tube. The ratio of yield point to strength limit is one of the characteristic indicators of whether the metal can withstand plastic deformation. The larger this ratio, the worse the plasticity of the metal. For industrially pure titanium in the cooled state, the ratio is 0.72-0.87, compared to 0.6-0.65 for carbon steel and 0.4-0.5 for stainless steel.

Volume stamping, free forging, and other operations related to machining large cross-sections and large-size blanks are carried out in the heated state (above the =μS transition temperature). The temperature range of forging and stamping heating is between 850-1150°C. Alloys BT; M)0, BT1-0, OT4~0 and OT4-1 have satisfactory plastic deformation in the cooling state. Therefore, the parts made of these alloys are mostly made of intermediate annealed blanks without heating and stamping. When the titanium alloy is cold plastically deformed, regardless of its chemical composition and mechanical properties, the strength will be greatly improved, and the plasticity will be correspondingly reduced. For this reason, annealing treatment between processes must be performed.
