Molybdenum’s prime alloy is TZM. This alloy contains 99% Mo, % Ti and % Zr. TZM offers twice the strength of pure molybdenum at temperatures over 1300° C.
Molybdenum is a versatile material that is routinely utilized in a wide number of markets. This dynamic range of performance is assisted by the material’s workability. Components manufactured from pure molybdenum and its alloys can be engineered via a range of techniques, including: Additive manufacturing; Powder Metallurgy; Arc Melting; Extrusion
For specialised applications, Mo is alloyed with many other metals: Mo-tungsten alloys are noted for exceptional resistance to molten zinc; Mo is clad with copper to provide low expansion and high conductivity electronic circuit boards; Mo-25% rhenium alloys are used for rocket engine components
Molybdenum--based Alloys QuesTek has combined Integrated Computational Materials Engineering (ICME) and our own Materials by Design? technology to design and develop new superior high performance molybdenum-based alloys for applications in aerospace and defense, automotive, energy and other markets.
In corrosion resistant nickel-based alloys, molybdenum imparts resistance to nonoxidizing environments such as the halide acids (HCl, HBr and HF) and sulfuric acid, for example. Accordingly, the alloy most resistant to these environments is B-3 alloy which contains % Mo. Molybdenum also acts in conjunction with chromium to provide resistance to localized corrosion attack such as pitting and crevice corrosion.
TZM alloy is a popular molybdenum-based alloy containing ±% zirconium, ±% titanium, ±% carbon and molybdenum makes up the balance. TZM is short for Titanium zirconium molybdenum alloy. The strength of TZM is two times that of pure Molybdenum when the temperature reaches 1300 degrees Celsius.
Yet in tests it resisted corrosion of a standard eutectic salt (FLiBe) and salt vapors used in molten salt reactors for 1100 hours with so little corrosion that it was difficult to molybdenum-based alloys that do not contain iron have only limited applications.
MHC is a particle-reinforced molybdenum-based alloy which contains both hafnium and carbon. Thanks to the uniformly distributed, extremely fine carbides, the material benefits from outstanding heat and creep resistance and, at 1,550 °C, the maximum recommended temperature of use is 150 °C higher than that of TZM.
The most widely used molybdenum-based alloy is the Titanium-Zirconium-Molybdenum alloy, TZM (composed of % titanium, % zirconium, % carbon, balance molybdenum). TZM accounts for ?90% of commercial molybdenum-based alloys currently in use.
Molybdenum is also valued in steel alloys for its high corrosion resistance and weldability. Molybdenum contributes corrosion resistance to type-300 stainless steels (specifically type-316) and especially so in the so-called superaustenitic stainless steels (such as alloy AL-6XN, 254SMO and 1925hMo). Molybdenum increases lattice strain, thus increasing the energy required to dissolve iron atoms from the surface.
