Spherical TaNbTiZr high entropy alloy powder 15-53μm

Spherical TaNbTiZr high entropy alloy powder is an alloy composed of four refractory metal elements (tantalum Ta, niobium Nb, titanium Ti and zirconium Zr).

1. Characteristics

- High entropy effect: Since the alloy is a mixture of multiple metal elements, this alloy has a higher entropy, which can effectively enhance its solid solution stability and improve high temperature resistance, corrosion resistance and other properties.

- High temperature resistance: The alloy can maintain excellent mechanical properties at high temperatures, such as high tensile strength and high fatigue resistance, and is suitable for extreme high temperature environments.

- Corrosion resistance: Due to the complex composition of the alloy, it can effectively resist oxidation, corrosion and thermal fatigue, especially in a strong oxidizing environment.

- Good thermomechanical properties: The particle morphology of the spherical powder gives it good fluidity and high-density filling characteristics in applications such as additive manufacturing.

2. Application fields

- Aerospace: Used in engines and high-temperature components (such as nozzles and rocket engine structures). Due to its high temperature stability and corrosion resistance, it is suitable for use in extreme high temperature environments.

- Nuclear energy field: As a structural material in high temperature and radiation environment, it is particularly suitable for high temperature and radiation resistant materials in nuclear reactors.

- Military application: The alloy powder can be used in weapon systems in high temperature and high pressure environments, such as missiles, aircraft and other fields.

- Additive manufacturing: Due to its good powder fluidity, it is suitable for use as a metal powder material in additive manufacturing technologies such as 3D printing and laser melting.
