Original Title: GH1015 (GH15, GR5) Superalloy Plate | Pipe | Strip GH1015 I. Introduction of GH1015: GH1015 is a FE-NI-CR based solution strengthened wrought superalloy, which is used at temperatures below 950 degrees. The alloy is solution strengthened by adding elements such as chromium, tungsten and molybdenum. The alloy has high plasticity, medium endurance and creep strength, good cold and hot fatigue resistance, good processing and welding performance and structural stability. The main products are cold rolled sheet, titanium bar gr5 , wire and forgings. II. Application and characteristics of GH1015: GH1015 alloy has been used to manufacture plate structural steel and other high-temperature components such as aero-engine combustion chamber and afterburner cylinder. The alloy has a certain age hardening phenomenon when working for a long time at the temperature of 700 deg C to 900 deg C, so that the room temperature plasticity is reduced; and the alloy has a tendency to be oxidized along the grain boundary when working for a long time at the temperature of more than 700 deg C, so that an enamel coating can be used for effective protection. The high temperature oxidation resistance above 1000 degrees is slightly worse than that of nickel-based alloys for similar purposes. III. Similar grades of GH1015: High temperature new name: GH1015 High temperature old name: GH15 New name for corrosion resistance Old name for corrosion resistance GB grade: GR5 The alloy can be used as a substitute for GH2039, GH3030, GH3044 and GH3536 alloys.

Original Title: Introduction to Common Technologies for Hot Extrusion of Titanium Alloy Bars Introduction of Hot Extrusion Technology for Titanium Alloy Bar The hot extrusion of titanium alloy rod is to extrude the powder under the condition of increasing the temperature, so that the product can achieve full densification. Hot extrusion can accurately control the composition of the material and the internal structure of the alloy. Hot extrusion method can be divided into two forms: jacketed hot extrusion method and non-jacketed hot extrusion method. For the active metal titanium and titanium alloy powder,Titanium welding pipe, in order to prevent the product from oxidation, the hot extrusion method is often used. At this time,Titanium welding pipe, first make the sheath, put the powder or compact in the sheath, titanium filler rod ,titanium bar grade 5, after pre-pumping and sealing, put it in the extruder for hot extrusion. At this time, the sheath material used should have good thermoplasticity, not form full gold with the release material, easy to peel off after hot extrusion, convenient source and low cost. Low carbon steel or stainless steel sheet is mostly used. The first process of hot extrusion of titanium alloy bar is to combine forming, sintering and hot working together, so as to directly obtain a drill product with better mechanical properties. The second process of titanium alloy bar is to form titanium and titanium alloy powder. After sintering, the prepared sintered blank is subjected to hot extrusion (for Ti-32Mo alloy, the temperature is 1000-1100 deg C) to obtain the performance of the titanium alloy product. Effect of extrudate ratio on the properties of titanium. It can be seen from the table that a titanium material with a theoretical density of 98.6% -99.1% can be obtained. The third process of titanium alloy bar is the extrusion process of filling blank,ti6al4v eli, which is an important method that can be used to make products with complex sections. The process includes the following steps: preparing sheathing cavity, determining the size of the cavity according to the required final product size and extrusion coefficient; sheathing. Filling the powder into the cavity and vibrating and compacting; evacuating, exhausting and sealing the sheath; extruding at a certain temperature and extrusion ratio; and stripping the sheath.

Original Title: Dimensional Specifications for Titanium Bars, Plates, Tubes, and Wires Dimensional specifications for titanium rods, plates, tubes and wires The dimension of titanium is one of the basic knowledge of titanium. The dimension of titanium generally refers to the length of titanium. The length of titanium mainly includes length, width, height, diameter, radius,titanium round bar, inner diameter, outer diameter and wall thickness. The length of titanium is measured in meters (m), centimeters (cm), millimeters (mm),titanium bar gr7, and so on. They need to understand titanium materials, including titanium rods, titanium plates, titanium tubes, titanium wires and so on, which are rolled from titanium and titanium alloys. Expand the full text 1. Size determination of titanium material It is a useful way to save information. Scale sizing means that the length or length multiplied by width is not less than a certain scale, or the length of titanium plate. Length by width from how many to how many dimensions within the scale of delivery. The production unit can produce and supply according to the demand of this scale. 2. No fixed length It refers to the general length, titanium round bar ,titanium tubing price, where the product scale (length or width) is within the standard and regular scale, and does not require a fixed scale, it is called an indefinite scale. Indefinite length is also called general length. Metal materials delivered to indefinite length, as long as they are delivered within a regular length scale. For example, if the general length rule of general round titanium not larger than 25mm is 4-10m, the round titanium with length within this scale can be delivered. 3. Fixed length Cut to a fixed size according to the order requirements is called fixed length. When the goods are delivered according to the fixed length, the delivered metal data must have the length specified by the buyer in the order contract. For example, if it is specified in the contract that the goods shall be delivered according to the fixed length of 5m, the delivered materials must be 5m long, and those shorter than 5m or shorter than 5m are unqualified. But in fact, the delivery can not be 5 meters long, so the rule allows positive error, but not negative error. 4. Double scale If it is cut into an integral multiple according to the fixed scale of the order demand, it is called a multiple scale. When the goods are delivered in multiple lengths, the length of the delivered metal material must be an integral multiple (plus a saw cut) of the length (called a single length) specified by the demander in the order contract. For example, if the demander requires a single length of 2m in the order contract, then the length is 4m when it is cut into double lengths, and 6m when it is cut into triple lengths, plus one or two saw cuts separately. The amount of kerf is regulated in the specification. When multiple ruler delivers goods, allow to have positive error only, do not allow to present negative deviation value. 5. Narrow ruler If the width is less than the lower limit of the irregular width of the standard rule, but not less than the narrowest width allowed, it is called a narrow ruler. When delivering goods in narrow sizes, it is necessary to pay attention to the narrow size share and the narrowest size of the relevant normative rules. 6. Short ruler If the length is less than the lower limit of the indefinite length of the titanium tube specification, but not less than the shortest length allowed,3d titanium wire, it is called a short ruler. For example, the rule in the specification of titanium pipes for water and gas transportation allows 10% (calculated according to the number of pipes) of short titanium pipes with a length of 2-4m in each batch. 4m is the lower limit of indefinite length, and the shortest length allowed is 2m.

Original title: Titanium alloy exhaust pipe Titanium alloy exhaust pipe Stainless Steel Exhaust and Titanium Alloy Exhaust-Car The modified exhaust can not only discharge the waste more smoothly, but also make the sound more obvious; Stainless steel and titanium alloy are the mainstream materials in the modified exhaust market. Most modified players prefer stainless steel,titanium seamless tube, which is also the mainstream of exhaust in the market. There are three specific differences between them: I. Weight In the case of the same volume, the weight of titanium alloy material is lighter than that of stainless steel material. The weight of titanium alloy material can be more than one third lighter than that of stainless steel material,Titanium 6Al4V wire, and its rigidity is better, which can fully meet the needs of players who pursue lightweight. Stainless steel exhaust Heat resistance and heat dissipation Although the exhaust gas can withstand high temperatures now, titanium exhaust tubing ,nickel titanium wire, the heat resistance and heat dissipation of titanium alloy are still better than that of stainless steel. Titanium alloy exhaust Three, sound waves Because the titanium alloy exhaust pipe wall is thinner than the stainless steel exhaust, the sound of the titanium alloy exhaust will be higher, and the stainless steel exhaust will be thicker and deeper. These are some of the differences between titanium alloy and stainless steel. Although titanium alloy has better exhaust rigidity, better heat resistance and lighter weight, the mainstream of the market still prefers stainless steel. Because of the high cost of titanium alloy and the more difficult processing, the higher the purity of titanium alloy, the better the degree of tensile bending, the higher the heat resistance,titanium plate gr7, and the more expensive the exhaust price. Therefore, according to the different needs of players, the orientation of their selection will also be different. Return to Sohu to see more Responsible Editor:. yunchtitanium.com

Original Title: TC4 Heat Treatment TC4Ti-6Al-4V Elongation Properties 1, TC4/Ti-6Al-4V titanium alloy With the development of aviation industry, the demand for high-end superalloys continues to grow. High temperature titanium alloys are widely used in aviation industry due to their high specific strength. In particular, the application of high-temperature titanium alloys in aero-engines can reduce the mass of the engine, improve the fuel output power and reduce noise. The main high temperature titanium alloys at home and abroad are Ti1000 in the United States, IMI834 in the United Kingdom, BT36 in Russia and Ti600 in China. These titanium alloys have high instantaneous strength and creep strength at high temperature. High performance TC4/Ti-6Al-4V titanium alloy bar is the most widely used high strength titanium alloy profile at present. By changing the alloy element content and improving the processing technology, better high temperature performance can be obtained, which is of great significance in actual production and research and development. For TC4 titanium alloy with different composition and processing technology, it is also of great significance to test whether it has the creep performance in line with the actual production requirements. Because TC4 titanium alloy is mainly served at 400 ℃ at present,6al4v titanium bar, the multi-stress creep data of TC4 titanium alloy at this temperature were tested, the time-stress curve under certain residual deformation was drawn, and the creep properties of TC4 titanium alloys were analyzed and discussed. 1.1 Its high temperature creep performance directly affects the development and use of materials. The creep test of TC4 titanium alloy bar, which is the most widely used at present, was carried out to analyze the relationship between the total elongation,3d titanium wire, residual deformation stress and time under the condition of 400 ℃ and certain residual deformation. The results show that at 400 ℃, the time required for the creep stabilization process of TC4 titanium alloy bars decreases with the increase of the test stress, and the steady-state creep rate increases with the increase of the test stress. 1% and 0. Under the condition of 2% residual deformation, the relationship between the test stress and the test time in the test stage is approximately linear when the logarithm is taken. Effect of heat treatment on microstructure and properties of titanium alloy At present, in the process of analyzing the structure and performance of titanium alloy, the characteristics of heat treatment should be clarified first. Heat treatment mainly depends on the decomposition operation of metastable phase formed by two-phase titanium alloy during quenching, so as to ensure that there will be no obvious strengthening problem during martensitic transformation in titanium alloy. At the same time, ti6al4v eli ,titanium plate gr7, allotropic transformation will occur in titanium alloy. And then it is difficult to play a role in refining the titanium alloy, because the thermal conductivity of the titanium alloy is relatively poor, so if the problem of local deformation or temperature rise occurs, Widmannstatten structure will be formed, and then the thermal conductivity of the whole titanium alloy material will be reduced, especially in the process of heat treatment for some alpha plus beta titanium alloys, because the quenching thermal stress is relatively large, Therefore, it is very easy to cause bending problems of titanium alloy parts. 2.1 Because the chemical properties of titanium and titanium alloy substances are relatively active, and hydrogen evolution reaction is very easy to occur, causing hydrogen embrittlement problems, so in the process of heating titanium alloy substances with heating furnace, the atmosphere must be strictly controlled, and titanium and titanium alloy substances are also easy to react with water vapor and oxygen. Then the dense oxide layer appears on the surface of the titanium alloy, which affects the performance of the whole titanium alloy. Therefore, the influence of the oxide layer should be clarified in the process of heat treatment. Expand the full text 2.2 The phase transformation temperature of titanium alloy will be affected by the melting conditions and parameters, such as the vacuum degree in the heating furnace, the times of melting and the impurity content, which will have a certain impact on the phase transformation temperature of titanium alloy, especially when the titanium alloy substance is heated in the beta type, the growth tendency of beta type titanium alloy is relatively large. Therefore, the heating temperature and holding time should be strictly controlled at this time to prevent the plasticity and other properties of grains from being affected during the heat treatment process of β-type titanium alloy. At this stage, the use of heat treatment process will have a certain impact on the microstructure and properties of TC4 titanium alloy, because the application of titanium alloy is more and more extensive, so it is of great significance to explore its specific impact.
