The key process of TZM sheet from powder metallurgy to precision rolling
TZM plate (titanium zirconium molybdenum alloy plate) is a high performance superalloy material based on molybdenum, with its unique high temperature strength, creep resistance and corrosion resistance, becoming the ideal choice in extreme conditions.
1. Aerospace: Key materials for thermal protection and propulsion systems
TZM sheet mainly serves high-temperature components in the aerospace field, and its core applications include: rocket engine nozzle: TZM plate can withstand high temperature gas erosion above 2000°C, and excellent thermal shock resistance, compared with traditional nickel-based alloy weight reduction of more than 30%, significantly improve the thrust-weight ratio. Re-entry thermal shield: The low coefficient of thermal expansion (4.8×10-6/°C) and high temperature stability of TZM plate are used to prevent the spacecraft from structural deformation due to severe aerodynamic heating.
2. Nuclear energy industry: radiation and corrosion resistant structures
In nuclear reactors and fusion devices, TZM plate applications focus on extreme radiation and corrosive environments: Nuclear fuel cladding materials:
TZM plates have a small neutron absorption cross section (thermal neutron cross section 2.6b) and corrosion rates in liquid metal coolants (such as lead-bismuth alloys) are 50% lower than stainless steel. First wall material of fusion reactor: In the face of 14MeV high-energy neutron irradiation, TZM plate inhibits helium bubble aggregation through carbide strengthening phase and prolonging service life.
3. High temperature industry: heat resistant equipment and energy saving
TZM sheet plays a core role in metallurgy, glass manufacturing and other high-temperature industries: high-temperature furnace heating body: The resistance heating body made of TZM sheet can work continuously for more than 1000 hours in the air of 1600°C, and the energy consumption is 40% lower than that of graphite electrode. Glass furnace electrode: TZM plate has excellent corrosion resistance to molten glass (annual loss rate < 0.1mm), avoiding glass pollution caused by oxidation of traditional molybdenum electrodes.
4. Electronic devices: semiconductor and high-end equipment substrate
In the field of microelectronics and precision manufacturing, the characteristics of TZM board are deeply developed: high-power semiconductor substrate: the thermal conductivity of TZM board (142 W/m·K) is highly matched with the silicon chip, which can solve the heat dissipation bottleneck of IGBT module and increase the device life by more than 30%. Sputtering target material: Ultra-high purity (≥99.95%) TZM plate is used to prepare nanometer molybdenum film, which is used in OLED display and photovoltaic cell electrode.
5. Medical equipment: high-precision radiation therapy components
The innovative application of TZM plate in the medical field is gradually emerging: proton therapy collimator: Using the high density (10.2g /cm3) and radiation resistance of TZM plate, the proton beam path is accurately regulated, and the error is controlled within ±0.1mm. Medical linear accelerator target: TZM plate produces stable X-ray intensity under electron bombardment, and the service life is twice that of traditional tungsten target.
TZM board with its irreplaceable high temperature comprehensive performance, in aerospace, nuclear energy, electronics and other high-end fields continue to expand the application boundary. With the development of TZM plates for nuclear fusion and the progress of TZM plate surface functionalization technology, its market penetration will be further improved in the future and become the strategic core in the field of high-temperature engineering materials.
