TC4 titanium rod common processing standards and technical requirements

TC4 titanium rod common processing standards and technical requirements

Titanium is a metallic element, gray, with atomic number 22 and relative atomic mass 47.867. Can burn in nitrogen, high melting point. Passive titanium and titanium-based alloys are new structural materials, mainly used in the aerospace industry and the marine industry. Because titanium has the characteristics of high melting point, small specific gravity, high specific strength, good toughness, fatigue resistance, acid and alkali corrosion resistance, low thermal conductivity, good high and low temperature tolerance, and low stress under rapid cooling and rapid heating conditions, its commercial value is in In the 1950s, it was recognized by people and used in high-tech fields such as aviation and aerospace. And continue to promote to chemical, petroleum, electric power, desalination, construction, daily necessities and other industries.Titanium rods and forgingsProduct parametersGrade:International grade: TA1、TA2、TA3、TA7、TA9、TA10、TC4、TC4ELI、TC6、TC9、TC10、TC11American grade: GR1、GR2、GR3、GR5、GR7、GR12Process:Hot forging - Hot Rolling - Turning (polishing)Titanium rodsImplementation standard:National standard: GB/2965-2007, GB/T13810, Q/BS5331-91American Standard: ASTM B348, ASTM F136, ASTM F67, AMS4928Specifications: (diameter*length/mm):8mm-250mm*LSupply state: hot working state, annealing stateReference Standard:1.

TZM alloy

TZM alloy

The common preparation methods of TZM alloy (molybdenum zirconium titanium alloy) are: arc melting-casting method and powder metallurgy technology. The arc melting-casting method of TZM alloy rod is to melt pure molybdenum with electric arc, add a certain amount of alloying elements such as Ti and Zr by weight percentage, and then obtain TZM alloy (molybdenum zirconium titanium alloy) by conventional casting method; powder metallurgy has unique characteristics. chemical composition and mechanical and physical properties that cannot be obtained by traditional casting methods. The high-purity molybdenum powder is uniformly mixed with TiH2 powder, ZrH2 powder and graphite powder in proportion, and then formed by cold isostatic pressing, and then sintered at high temperature in a protective atmosphere to obtain a TZM billet. The billet is then subjected to high temperature hot rolling (high temperature forging), high temperature annealing, medium temperature hot rolling (medium temperature forging), medium temperature annealing to eliminate stress, and then warm rolling (warm forging) to obtain TZM finished material. The rolling (forging) process of the billet and the subsequent heat treatment have a great influence on the properties, anisotropy and texture of the material. The use of powder metallurgy can save large equipment such as vacuum consumable electric arc furnaces, large extruders, forging hammers, and corresponding high-temperature heating furnaces, simplify the process, shorten the production cycle, reduce energy consumption, and double the production capacity and yield. , so the cost is greatly reduced.

Zirconium and its application

Zirconium and its application

Since ancient times, zirconium has been regarded as a precious stone because of its colorful colors and plays a decorative role in human life. With the deepening of people's understanding of zirconium, the application of zirconium has become more and more extensive. Perhaps most people are relatively unfamiliar with zirconium, but it has penetrated into all aspects of our lives. For example, various buildings around, ceramics, knives, decorations, etc. that are indispensable in life, and even the military and nuclear power fields are also indispensable for zirconium.There are many kinds of zirconium products and various forms. The initial mineral form is zircon sand. After caustic soda, water washing, etc., primary products such as zirconium silicate and zirconium oxychloride can be produced. Zirconia, industrial-grade zirconium sponge and other products; if the level of purification and separation technology reaches a certain level, it can be made into nuclear-grade zirconium sponge.Zirconium has a wide range of applications, mainly in the form of zirconium silicate and zirconium oxide in ceramics, refractories and other fields. Only 3%-4% of zirconium ore is processed into metal zirconium (or sponge zirconium), which is further processed into various zirconium materials. Due to the small thermal neutron absorption cross section of metal zirconium, metal zirconium has excellent nuclear properties. Shell etc. Nuclear grade zirconium can be regarded as an important strategic metal for the country and is closely related to the development of the nuclear industry. As an active metal, zirconium forms an oxide film at room temperature. This oxide film makes zirconium and its alloys have excellent corrosion resistance. At the same time, zirconium has good mechanical and heat transfer properties, coupled with significant cost advantages, making it an excellent corrosion-resistant structural material in today's petrochemical industry. Zirconium used in chemical acid and alkali resistant equipment, military industry and electronics industry is called industrial grade zirconium. In terms of ease of processing, technological level and technological content, zirconium metal and its alloy products are at the top of the industrial chain. Zirconia Structural CeramicsMade from composite zirconia, including zirconia grinding media and zirconia structural parts, zirconia structural parts mainly include zirconia special ceramic valves, optical fiber connectors, ceramic knives, watch accessories, ceramic push scissors Sheets, textile porcelain, etc.Nuclear grade zirconiumIt is mainly used as a structural material for nuclear powered aircraft carriers, nuclear submarines and civilian power generation reactors, as cladding of uranium fuel elements, etc., and is an important strategic metal.Industrial grade zirconiumIndustrial grade zirconium is mainly used to make chemical acid and alkali resistant equipment, military industry, electronic industry, pipeline valve material, special high-strength and high-temperature alloy material, electric vacuum and getter for lighting bulb industry.Firearms Grade ZirconiumIt is used as a firearm sponge zirconium burner, as well as alloy additives and metallurgical deoxidizers, chemical industry, civil flash fireworks, etc.Global zirconium consumption areaAt present, China and Europe are the main consumer markets for zirconium, and China's demand for zirconium accounts for as high as 52%. China's nuclear power has entered a stage of rapid development, which has led to the demand for nuclear-grade zirconium. At the same time, China is a major producer and exporter of the world's ceramic industry, and zirconium silicate is the direct and main raw material for the ceramic industry. With the rapid development of China's ceramic industry in recent years, the demand for zirconium has also soared.
