What are the states of titanium tubes?

The states of titanium tubes can be divided into three types, including precipitation hardening state, superplastic state and α+β structure.

1. Precipitation hardening state: Titanium tubes after aging treatment have good strength and hardness at room temperature, and are suitable for heat exchangers in harsh environments such as high temperature and high pressure.

3. α+β structure: Titanium tubes mainly composed of α phase and β phase have medium strength, good plasticity and good welding performance, and are suitable for heat exchangers at medium temperatures.

When selecting and using titanium tubes, the state of titanium tubes needs to be determined according to actual conditions and needs. For example, heat exchangers used in harsh environments such as high temperature and high pressure need to use precipitation hardened products, while in applications that require good plasticity and toughness, superplastic products can be selected. At the same time, other parameters of the product, such as material, weight, specifications, etc., need to be considered to ensure that the performance and quality of the product meet the requirements.

Please note that the processing and treatment technology of titanium tubes also has some influence on their state. Therefore, when selecting and using products, you need to understand its processing and treatment technology to ensure that its state meets the use requirements.

What are the characteristics and advantages of titanium pipe fittings? Where will titanium pipe fittings be used?

The titanium in titanium pipe fittings has stable chemical properties and good biocompatibility, and its corrosion resistance and stability are also relatively high. It is a metal that has no effect on people's bodies and will not cause overreactions.

The characteristics of titanium pipe fittings are mainly reflected in the following aspects:

1. Corrosion resistance

Titanium pipe fittings have relatively high corrosion resistance. Even when working in humid air and seawater media, their corrosion resistance is significantly higher than that of stainless steel. Therefore, when using titanium pipe fittings, there is no need to worry about their lifespan. The corrosion resistance of titanium pipe fittings is 15 times stronger than that of stainless steel, and the service life is about 10 times longer than that of stainless steel.

2. Low temperature resistance

Titanium pipe fittings can still maintain their mechanical properties even under low temperature conditions, and are very resistant to low temperatures.

3. High strength

The density of titanium alloy is generally around 4.51g/cubic centimeter, which is 60% of steel, and the strength of titanium pipe fittings is relatively high, far greater than the strength of other metal structural materials. titanium foil sheet / titanium pipe fitting / Gr2 Pure Titanium Sheet

4. High thermal strength

The thermal strength of titanium pipe fittings is relatively high, and they can maintain the state for a long time even at 450-500℃. Generally speaking, the working temperature of titanium alloy can reach below 500℃, while the working temperature of aluminum alloy is generally below 200℃.

5. Smooth and scale-free

The titanium in titanium pipe fittings has low density, light weight, smooth surface and no scale. When we use titanium pipe fittings in our lives, the scaling coefficient will be greatly reduced.

Because titanium pipe fittings have the above 5 characteristics, they are widely used in chemical equipment, offshore power generation equipment, seawater desalination equipment, ship parts, electroplating industry and other industries.

What are the forging methods of titanium metal materials?

Forging is a forming method for manufacturing mechanical parts, workpieces, tools or blanks by applying external force to titanium metal billets (excluding plates) to cause plastic deformation, change size, shape and improve performance. In addition, according to the movement of the slider, there are also vertical and horizontal movement of the slider (used for forging of slender parts, lubrication and cooling, and high-speed production of parts forging), and the use of compensation devices can increase the movement in other directions. The above methods are different, and the required forging force, process, material utilization, output, dimensional tolerance and lubrication and cooling methods are different. These factors are also factors that affect the level of automation. According to the movement of the billet, forging can be divided into free forging, upsetting, extrusion, die forging, closed die forging, and closed upsetting. Grade 12 Ti-0.3Mo-0.8Ni Titanium Foil / F2 Pure Titanium Forging / 6al4v titanium plate

Because closed die forging and closed upsetting have no flash, the utilization rate of materials is high. The finishing of complex forgings can be completed in one or several processes. Because there is no flash, the force area of ​​the forging is reduced and the required load is also reduced. However, it should be noted that the blank cannot be completely restricted. To this end, the volume of the blank should be strictly controlled, the relative position of the forging die should be controlled, and the forging should be measured to reduce the wear of the forging die. According to the movement mode of the forging die, forging can be divided into pendulum rolling, pendulum rotary forging, roll forging, wedge cross rolling, ring rolling and oblique rolling. Pendulum rolling, pendulum rotary forging and ring rolling can also be processed by precision forging. In order to improve the utilization rate of materials, roll forging and cross rolling can be used as the front process of slender materials. Rotary forging, like free forging, is also partially formed. Its advantage is that it can be formed under a smaller forging force than the size of the forging. In this forging method, including free forging, the material expands from the vicinity of the die surface to the free surface during processing, so it is difficult to obtain high precision. Therefore, by controlling the movement direction of the forging die and the rotary forging process with a computer, products with complex shapes and high precision can be obtained with lower forging forces, such as forgings such as turbine blades with many varieties and large sizes. In order to obtain high precision, attention should be paid to preventing overload at the bottom dead center and controlling the speed and die position. Because these will affect the tolerance, shape accuracy and life of forging dies.

In addition, in order to maintain accuracy, attention should also be paid to adjusting the clearance and rigidity of the slider rail, adjusting the bottom dead point and using auxiliary transmission devices. The materials used for titanium forging are mainly pure titanium and titanium alloys of various compositions. The original states of the materials are bars, ingots, metal powders and liquid metals. The ratio of the cross-sectional area of ​​the metal before deformation to the cross-sectional area after deformation is called the forging ratio. Correctly selecting the forging ratio, reasonable heating temperature and holding time, reasonable initial forging temperature and final forging temperature, reasonable deformation amount and deformation speed has a great relationship with improving product quality and reducing costs. Generally, small and medium-sized forgings use round or square bars as blanks. The grain structure and mechanical properties of the bars are uniform and good, the shape and size are accurate, the surface quality is good, and it is easy to organize mass production. As long as the heating temperature and deformation conditions are reasonably controlled, forgings with excellent performance can be forged without large forging deformation.

What are the main mechanical properties of titanium rods?

The mechanical properties of titanium rods mainly include tensile strength, yield strength, elongation, shrinkage, etc. These performance indicators can reflect its performance under external forces, which is of great significance for its application and safety of use. AMS 4928 Titanium Alloy Bar / Grade 2 Titanium Bar / Titanium Industrial Rod

1. Tensile strength: refers to the maximum strength of titanium rods without breaking under tensile force, usually expressed in MPa (megapascals). Tensile strength is a very important indicator of its mechanical properties, which can reflect the strength and bearing capacity of titanium rods under tensile force.

2. Yield strength: refers to the phenomenon that the deformation of titanium rods suddenly increases when they are subjected to external forces less than the maximum tensile stress, usually expressed in MPa. Yield strength reflects its strength and bearing capacity when subjected to plastic deformation.

3. Elongation: refers to the maximum elongation of titanium rods before breaking under tensile force, usually expressed in percentage. Elongation reflects its plastic deformation ability and can reflect the overall plastic properties of titanium rods under external forces.

4. Shrinkage rate: refers to the degree of cross-sectional shrinkage of the titanium rod under the action of compression force, usually expressed as a percentage. The shrinkage rate reflects its compactness and stability under the action of compression force.

In addition to the above mechanical performance indicators, titanium rods also have good corrosion resistance and high strength, suitable for various high-demand application scenarios. At the same time, its mechanical properties will also be affected by factors such as production process, ambient temperature, and loading speed. In practical applications, it is necessary to select and optimize according to the specific use environment and process requirements to ensure its safety and reliability.

Titanium bar rolling for empty use

Heating characteristics and hot rolling characteristics of die forged blades and bars used in fastener manufacturing. The batch materials used by the former Soviet Union to manufacture aviation blades were titanium alloy rods such as BT3-1, BT8, BT9, and OT4 with a diameter of 10-60mm. Materials for aviation fasteners generally use BT16 titanium alloy rods with a diameter of 4.0-16mm.

The heating characteristics and hot rolling characteristics of BT3-1, BT8, BT9, and OT4 alloys determine the requirements for bar quality. For example, when hot rolling at the temperature of the ot+p phase zone of the alloy, if the deformation is not less than 40%-50%, then the plasticity and fatigue strength indicators of this material are the highest. However, rolling at this temperature can significantly increase the deformation resistance of the blanking pass and the intermediate pass, increase the unit pressure, and overload the rolling mill's motor. 6al4v titanium bar / Grade 12 Titanium Rod / Grade 2 Titanium Round Bar

In this case, the rolling process should be carried out in two stages:

(1) Pre-milking at a temperature higher than a +p-P transition;

(2) Roll to finished size at the ot +P phase zone temperature of the alloy. In the final rolling stage, the rolled material should be cooled to a temperature below 650T.

Bars with a diameter greater than 8.0mm, and restocked bars with a diameter of 4.0-8.0mm, should be rolled in one pass.

Development characteristics of titanium alloy materials and product processing technology

Due to the high manufacturing cost of titanium alloys, in order to reduce costs, the competitiveness of titanium alloys in the entire metal material market has been improved at a lower price. It is generally believed that titanium has incomparable superior performance compared with other materials, but the price of titanium often makes consumers (especially automakers) discouraged. The emergence of high-quality, low-cost titanium alloys will surely help promote the application of titanium and titanium alloys.

From the current application status at home and abroad and the development of titanium processing technology, the plastic processing technology of titanium and titanium alloys will develop in the following directions in the future:

1) High performance, that is, the development of alloys with higher operating temperature, higher specific strength, higher specific modulus, better corrosion resistance and wear resistance. titanium grade 2 strip coil / Titanium Stub End / Grade 2 Pure Titanium Plate

2) Multifunctional, that is, the development of titanium alloys with various special functions and uses, such as high damping, low expansion, constant resistance, high resistance, anti-electrolytic passivation and hydrogen storage, shape memory, superconducting, low modulus biomedical and other titanium alloys, to further expand the application of titanium and titanium alloys.

3) Deepen the research on traditional alloys, improve the practical performance of existing alloys, and expand the application range of traditional alloys through the improvement of equipment and processes.

4) Adopt advanced processing technology and large-scale continuous processing equipment, develop continuous processing technology, direct rolling technology, cold forming technology and near-net forming technology, and improve the production efficiency, yield rate and product performance of titanium alloys.

5) Reduce costs, develop alloys that contain no or almost no precious metal elements, and add cheap elements such as iron, oxygen and nitrogen to develop titanium alloys that are easy to process and form, easy to cut, and cheap in alloying elements and master alloys. Develop titanium alloys, use banned materials, and improve the recovery rate and utilization rate of banned titanium. This is particularly important for reducing the cost of civilian titanium alloys.

6) Use advanced computer technology to simulate the deformation and processing process of workpieces, predict the evolution of metal microstructures, and even predict the mechanical properties of products (yield strength, tensile strength, elongation and hardness, etc.). And design or improve molds and tooling; analyze and process test results, reduce the amount of testing, improve work efficiency, and reduce development costs.

Explain why titanium alloy is difficult to process

The machinability of titanium alloy is 20-40% of 45# steel. If the hardness is <HB300, there will be a strong sticking phenomenon; if HB>370, it is too hard to process. The best titanium alloy with a hardness of HB300-370 is the best. The main reasons affecting its machinability are briefly described as follows: 1) Gaseous impurities (oxygen, nitrogen and hydrogen, etc.) have a great influence on the machinability of titanium alloy, because titanium is highly chemically active and easily combines with gas impurities. When the temperature exceeds 600 degrees, titanium is oxidized to form a brittle layer, the so-called "organization α layer"; it produces hydrogen embrittlement with hydrogen; and forms hard and brittle TiN with nitrogen at high temperature. 2) Titanium alloy has low plasticity, which significantly affects its plastic deformation during cutting. The deformation coefficient of titanium alloy is only 1 or even less than 1, while the deformation coefficient of ordinary carbon steel is about 3. When cutting, the chip has a very small contact surface with the front cutting edge, which makes the pressure and local temperature of the contact area high, and the tool wears quickly. 3) Severe work hardening will occur during titanium alloy processing. Grade 23 Ti-6Al-4V ELI Titanium Foil / F9 Titanium Forging / ASTM B265 Cold Rolling Titanium Sheet
