The main component of the TZM molybdenum alloy is Mo-(0.4%–0.55%)Ti-(0.06%–0.12%)Zr-(0.01%–0.04%)C.
Titanium (Ti), zirconium (Zr), and carbon (C) are added to pure molybdenum. Mo-Ti trace elements, Mo-Zr solid solutions, and dispersed TiC and ZrC particles are formed in the molybdenum matrix, which provide solid-solution strengthening and dispersion strengthening effects to the molybdenum alloy, improving the recrystallization temperature and high-temperature mechanical properties of pure molybdenum.
TZM molybdenum is a molybdenum alloy containing titanium (Ti), zirconium (Zr), and carbon (C), hence its acronym “TZM.” This alloy is known for its excellent mechanical properties and high-temperature resistance, making it valuable in various demanding industrial applications.
Composition and Structure
The TZM molybdenum alloy typically consists of approximately 0.5 to 0.7% titanium, 0.07 to 0.2% zirconium, and 0.01 to 0.04% carbon, with the remainder consisting mainly of molybdenum. This specific combination of elements gives the alloy unique properties, including improved resistance to deformation at high temperatures and increased resistance to mechanical stress.
Physical and Mechanical Properties
Heat resistance
One of the key characteristics of TZM molybdenum is its exceptional heat resistance. It can withstand temperatures of up to 1,400 to 1,500 °C, making it an ideal material for high-temperature environments such as aerospace applications and industrial processes.
Mechanical Strength
TZM alloy has high mechanical strength, which enables it to withstand high loads and significant stresses without deforming. This makes it a valuable material for structural components subjected to severe conditions.
