CTIA’s TZM Alloy in Nuclear Structural Components

CTIA’s TZM alloy (Titanium Zirconium Molybdenum) is manufactured through powder metallurgy processes using high-purity molybdenum powder as the matrix. By adding Ti (0.40%–0.55%), Zr (0.06%–0.12%), and C (0.01%–0.04%), carbide phases (TiC and ZrC) are formed to provide dispersion strengthening, improving high-temperature strength, creep resistance, dimensional stability, and high-temperature microstructural stability. TZM meets the demanding requirements of nuclear industry equipment under long-term high-temperature exposure, thermal cycling, and complex service conditions. Nuclear structural components must maintain structural integrity and operational reliability in severe environments. CTIA’s TZM alloy is suitable for load-bearing components, support structures, connecting components, and other precision high-temperature structural parts, widely used in nuclear materials research, high-temperature testing equipment, and related nuclear industry equipment and systems.

Advantages of CTIA’s TZM Alloy in Nuclear Structural Components
(1) Superior High-Temperature Strength
Maintains high mechanical strength at elevated temperatures to withstand continuous operational loads and ensure structural stability.
(2) Good Creep Resistance
Minimizes dimensional changes during long-term high-temperature service, improving component reliability.
(3) High Dimensional Stability
A low coefficient of thermal expansion (approximately 5.5–5.9×10⁻⁶/K) reduces temperature-induced dimensional variations, meeting precision engineering requirements.
(4) High-Temperature Microstructural Stability
TiC and ZrC strengthening phases effectively inhibit grain growth, maintaining stable microstructure during long-term high-temperature exposure.
