Production Method for Ti22Al25Nb Powder

Ti22Al25Nb powder can be produced via methods like:

Gas Atomization – High pressure inert gas jet used to atomize molten alloy resulting in fine spherical powder ideal for AM.

Plasma Rotating Electrode Process (PREP) – Centrifugal disintegration of rapidly rotating molten metal into fine droplets yields spherical powder.

Mechanical Alloying – High energy ball milling of elemental/pre-alloyed powders followed by annealing and secondary atomization.

Gas atomization and PREP allow excellent control over powder characteristics like particle size distribution, morphology, and micro cleanliness.

Applications of Ti22Al25Nb Powder

Ti22Al25Nb powder is used in:

Additive Manufacturing – Selective laser melting to produce complex lightweight components like brackets, airfoils, impellers for aerospace and automotive.

Thermal Spray Coatings – Applied via plasma or HVOF spraying to provide wear/corrosion resistance for turbocharger blades and aerospace components at high temperatures.

Metal Injection Molding – To manufacture small, complex net-shape parts needing high specific strength up to 800°C like turbine blades.

Powder Metallurgy – Pressing and sintering to create low-density, high-strength parts like connecting rods.

Specifications of Ti22Al25Nb Powder

Ti22Al25Nb powder is available under various size ranges, shapes and purity levels:

Particle Size: From 15-45 μm for AM methods, up to 100 μm for thermal spray processes.

Storage and Handling of Ti22Al25Nb Powder

Ti22Al25Nb powder requires careful storage and handling:

Should be stored in sealed containers under inert gas like argon to prevent oxidation

Avoid accumulation of fine powder to minimize risk of dust explosions

Use proper PPE, ventilation, grounding and safety practices during powder handling

Prevent contact between powder and ignition sources due to flammability hazard

Follow applicable safety guidelines from supplier SDS

Care should be taken when handling this highly reactive alloy powder.

Inspection and Testing of Ti22Al25Nb Powder

Key quality control tests performed on Ti22Al25Nb powder:

Chemical analysis using ICP-OES or XRF to ensure composition meets specifications

Particle size distribution using laser diffraction as per ASTM B822 standard

Morphology analysis through SEM imaging

Powder flow rate measurement using Hall flowmeter as per ASTM B213 standard

Density measurement by helium pycnometry

Impurity analysis through inert gas fusion or ICP-MS

Microstructure characterization by X-ray diffraction

Thorough testing ensures batch consistency and powder quality for the intended application.

Comparison Between Ti22Al25Nb and Inconel 718 Powders
