Tungsten Filaments and Crucibles for Microprobe and Electron Beam Systems 164

Electron microscopes generate images by bombarding samples with electrons and then converting the results of this interaction into visual images. In order to form an image, the generated electrons need to be tightly controlled. Electron beams come from filaments made of various materials. The most common is the tungsten hairpin gun, which is widely used in scanning electron microscopes, transmission electron microscopes, and microprobe systems. This filament is a tungsten ring that acts as a cathode. Apply voltage to the…

Will Russia-Ukraine War Make Yttrium Tungsten Electrode (WY20) Price Increase? 165

Yttrium is a lanthanide metal found in most rare earth minerals, especially yttrium tantalite. It can be used as the yttrium phosphor to produce the red color on television screens and monitors and used as a superconductor and as a component of X-ray filters and superalloys. When added to tungsten as a rare earth element, it can be used as a welding electrode. Among the non-consumable electrodes, the yttrium tungsten electrode is the most consistent, so it is often used…

TZM Plate or TZM Sheet for Structural Furnace Components 233

Metal sheet/plate is a thin sheet/plate made from different materials of tungsten, tungsten alloys, molybdenum and molybdenum alloys. The sheet could be formed by hot rolling procedures and is polished further with different finishes depending on the applications. TZM has several valuable properties such as high strength, creep resistance, hardness and low vapor pressure in high temperature environments. Sheets/plates made of TZM alloy thus have low expansion coefficient, excellent heat and corrosion resistance and good machinability. Compared with pure molybdenum…

TZM Alloys for Radiation Shielding and Heat Exchangers 245

TZM, also known as titanium zirconium molybdenum, is a mature molybdenum alloy. The main advantage of using it is that it can well support applications where high strength and creep resistance are highly required. It is a stable metal and is not affected by temperature reduction and works well without weakening or softening. Alloying facilitates the vacuum arc casting process by which complete melting and mixing of molybdenum oxide and alloy is accomplished. Therefore, with the help of the two…
