Molybdenum and Nuclear Industry

Molybdenum neutron absorption cross section is small, has good strength , good stability of the nuclear fuel , good corrosion resistance to liquid metal in fusion reactors for converters armored elements protective sheet . Mo-Re alloys can be used for space nuclear reactors thermionic energy converter sheath materials , heaters, reflectors and other wire or sheet components.

And other molybdenum molybdenum alloy is a high -performance multi- alloying elements, not only in the steel added shows unique role, but also can generate excellent performance with a variety of non-ferrous alloys .

Adding molybdenum Ti, Zr, C oxides or carbides formed dispersion strengthened alloy TZM. TZM alloy addition to the application in the aerospace and nuclear industries , but also can be used for rotating anode X-ray parts , die casting molds and extrusion dies, in copper alloy extrusion , its operating temperature at 870-1200 ℃. TZM alloy is also very suitable for stainless steel hot piercing plug , perforated steel wall of good quality and long service life. Adding a small amount of rare earth elements TEM alloy has a higher recrystallization temperature recrystallization than ordinary molybdenum material ductility 5 times higher , there are good prospects .

Titanium , zirconium and carbon molybdenum alloy (MT-104), carbon -containing hafnium and molybdenum alloy (HCM) and tungsten , hafnium and carbon molybdenum alloy (HMW) has a higher strength , can be processed into rods , plates, forging stock and other products come in handy. Mo-30w is a solid solution alloy , the melting point to above 2800 ℃ , the zinc smelting for molten metal valve and shaft , fuel purification and plating equipment lines , mixing shaft, impeller pumps. Tungsten heavy alloy (90W-7Ni-3Fe) adding a certain amount of molybdenum, its strength and hardness are increased with the molybdenum content , which continue to lower the ductility , can greatly improve the performance of a projectile weapons material .

Molybdenum carbide (Mo2C) , and tungsten carbide mixed , add the appropriate lanthanum powder , sintered into a hard material, the thick broken after a certain amount of nickel and the usual carbide production method, a good distribution of the binder phase , dense and granular molybdenum carbide based cemented carbide . Metal binder phase using Co or Ni, can generate complex molybdenum - tungsten carbide based cemented carbide . Molybdenum carbide can also be added to the metal-ceramic in order to improve its performance.
