TZM Alloy Titanium-Zirconium-Molybdenum Alloy

TZM (Titanium-Zirconium-Molybdenum) Alloy: Superior Performance, Leading High-Temperature Applications

TZM alloy (Titanium-Zirconium-Molybdenum alloy) is a molybdenum-based alloy produced through powder metallurgy or vacuum arc-melting processes. It is formed by adding small amounts of titanium ($\sim 0.5\%$), zirconium ($\sim 0.08\%$), and traces of carbon ($\sim 0.01-0.04\%$), resulting in a dispersion-strengthened high-temperature molybdenum-based alloy. Compared to pure molybdenum, TZM molybdenum alloy utilizes the dual effects of solid solution strengthening and carbide dispersion strengthening to significantly improve its high-temperature strength, recrystallization temperature, creep resistance, and hardness. Simultaneously, it retains the inherent advantages of molybdenum, such as a high melting point, high thermal conductivity, and a low coefficient of thermal expansion. This makes molybdenum tzm alloy an ideal structural material for extreme high-temperature and high-stress environments.

Core Performance Advantages of TZM Molybdenum Alloy

• Excellent High-Temperature Strength: TZM alloy maintains considerably high strength and hardness at temperatures up to 1300∘C and even higher, performing significantly better than pure molybdenum and some other high-temperature alloys.
• High Recrystallization Temperature: Its recrystallization temperature is typically around 1400∘C, approximately 250−300∘C higher than that of pure molybdenum. This means the material resists softening and maintains structural stability when used at higher temperatures.
• Superior Creep Resistance: Under high temperatures and prolonged stress, TZM molybdenum alloy exhibits better resistance to plastic deformation, making it suitable for long-term load-bearing high-temperature components.
• High Thermal Conductivity and Low Coefficient of Thermal Expansion: It inherits molybdenum’s excellent thermal conductivity, aiding in rapid heat dissipation. Its low coefficient of thermal expansion ensures good dimensional stability and low thermal stress during drastic temperature changes.
• Good Machinability: Compared to pure molybdenum, molybdenum tzm alloy offers better ductility and workability (e.g., forging, rolling, machining) under certain conditions, although processes suitable for refractory metals are still required.
• Good Corrosion Resistance: It demonstrates good resistance to certain molten metals (like liquid zinc), molten salts, and inert gases.
