Processing performance of Tantalum

 

Processing performance

Tantalum has good plasticity, low deformation resistance, and low process hardening. It can be processed into plates, strips, foils, pipes, rods and wires at room temperature.

Tantalum can be formed into various devices & parts using traditional processes, equipment and tools such as metal spinning, deep drawing, bulging, bending, punching & cutting, stamping and drawing.

Machinability

The mechanical properties of fully recrystallized pure tantalum are similar to soft copper. In order to meet the tolerance and surface roughness requirements, the following machining method can be used: turning, milling, grinding and reaming, boring, tapping and others.

Welding performance

Tantalum has the best welding performance amount all refractory metals, and can be welded with carbon steel, stainless steel, nickel alloy, titanium alloy, etc. Electron beam welding and inert gas shielded tungsten arc welding can be used to weld tantalum chemical equipment components with ductility-brittleness transition temperature below room temperature, which can meet the requirements of chemical industry. Tantalum-Steel composite materials can be prepared by explosive welding, which is an effective way for manufacturing tantalum lining of large-scale corrosion-resistant equipment. We can use silver solder, copper solder and several special high-melting metal solder alloys for tantalum soldering connection.

Welding and brazing must be performed under vacuum or high purity inert gas. Resistance welding or seam welding can be performed in air or underwater.

Heat treatment

For best processability, tantalum is often used at a stress-relieved or recrystallized temper. The recrystallization temperature is determined by the purity, the amount of cold work, and historical conditions. Recrystallization temperature of pure tantalum plate with specific thickness is 1000-1250 ℃.

Alloying of molybdenum

图片
  The alloying principle of molybdenum is similar to that of tungsten. All the strengthening methods used to improve the heat resistance of tungsten are basically applicable to molybdenum. There are mainly the following types: solid solution strengthening, precipitation strengthening, dispersion strengthening and composite strengthening. Solution strengthening Solid solution strengthening includes the addition of trace elements and high content elements. The trace element solid solution strengthening method mainly refers to adding a trace amount of Ti, Zr, Fe, Mn, La, B and other alloy elements for solid solution strengthening to improve the performance of molybdenum. When trace elements are added, a certain amount of carbon is often added to the alloy. It is the alloy elements and carbon that form carbide dispersed particles to strengthen the strengthening effect. High content element solid solution strengthening The elements that improve the binding force between atoms...

Knowledge about TZM Alloy

  TZM material is an alloy of 0.50% Titanium, 0.08% Zirconium and 0.02% Carbon with the balance Molybdenum and is typically manufactured by powder metallurgy or arc-casting processes. It has a higher recrystallization temperature, higher creep strength & hardness, and higher tensile strength than pure molybdenum. In addition, TZM exhibits good thermal conductivity, low vapor pressure, good corrosion resistance and is machinable.   TZM Molybdenum Physical Properties: Density: 10.22g/cc, 0.37lb/in3 Melting Point: 2623°C, 4753°F Thermal Conductivity: 0.48 Cal/cm2/cm°C/sec Specific Heat: 0.073 Cal/gm/°C Coefficient of Linear Thermal Expansion: 2.50 micro-in/°F x 10-6 Electrical Resistivity: 6.85 micro-ohm-cm   The molybdenum TZM is a normally utilized constructional material for high-temperature applications. These microstructural aspects significantly affect quality at raised temperatures. By methods for carbide-reinforcing TZM features impro...

Tungsten tube-High density & melting point metal tube

图片
  Tungsten tubes are drilled from tungsten bars / rods, W tube with massive OD are going to be mold directly.   Tungsten – periodic symbol W - lays claim to the very best freezing point of all components. This characteristic combined with a superb ability to resist thermal shock enhances its ability to perform well as a conductor. Rocket cones, that should stand up to fast temperature changes and recurrent on and off cycles, area unit typically manufactured from tungsten. Tungsten's density conjointly permits it to expeditiously block radiation from sure areas whereas directional it to others. It will direct and form a beam of radiation, permitting doctors additional exactitude and management whereas treating cancerous tissue. With the employment of tungsten devices and shields, doctors area unit ready to target cancerous areas, whereas at the same time shielding healthy tissue from the harmful effects of radiation. Application The quartz production method uses c...
