Titanium and aluminum TA7 powder

TA7 powder belongs to the family of titanium aluminides, which are intermetallic compounds composed of titanium and aluminum. This unique powder exhibits exceptional strength, lightweight characteristics, and high-temperature stability, making it an attractive choice for numerous engineering applications.

Overview of Titanium and Aluminum TA7 Powder

TA7 belongs to the titanium-aluminide intermetallic alloy system combining the lightweight properties of aluminum with the strength and corrosion resistance of titanium. The near-equiatomic ratio of Ti and Al provides an excellent balance of properties for elevated temperature applications.

Key characteristics of TA7 powder include:

Very high specific strength (strength-to-weight ratio)

Excellent high temperature tensile and creep strength

Low density compared to nickel or steel alloys

Good corrosion resistance in various environments

Available in range of particle sizes and morphologies

TA7 powder has emerged as an excellent choice for reducing weight and improving efficiency in aerospace engines and airframes operating at high temperatures.

Chemical Composition of TA7 Powder

TA7 powder has the following nominal composition:

Element Weight %
Titanium (Ti) Balance
Aluminum (Al) 7%
Tin (Sn) 2-5%
Zirconium (Zr) 1-4%
Silicon (Si) 0.5% max
Carbon (C) 0.1% max
Oxygen (O) 0.13% max

Properties of TA7 Powder

Key properties of TA7 powder include:

Property Value
Density 3.7-4.0 g/cm3
Melting Point 1460°C
Thermal Conductivity 6.7 W/mK
Electrical Resistivity 1.78 μΩ.cm

The properties like high strength, low density, oxidation resistance and thermal stability make TA7 suitable for the most demanding elevated temperature applications.

Production Method for TA7 Powder

TA7 powder can be produced via methods like:

Gas Atomization – High pressure inert gas used to atomize molten TA7 alloy resulting in spherical powder ideal for AM.

Plasma Rotating Electrode Process – Centrifugal disintegration of rapidly rotating molten metal stream produces spherical powder.

Mechanical Alloying – High energy ball milling of blended elemental Ti and Al powders followed by annealing.

Gas atomization provides excellent control over powder characteristics like particle size distribution, morphology, microcleanliness and flowability.

Applications of TA7 Powder

TA7 powder is commonly used in:

Additive Manufacturing – Selective laser melting to produce complex airfoil shapes, impellers, turbine blades.

Metal Injection Molding – To manufacture small, complex net-shape parts like turbocharger components needing high strength and temperature resistance.

Thermal Spray Coatings – Applied via plasma or HVOF spraying on valve surfaces, bearings, landing gear components needing wear/corrosion resistance at high temperatures.

Powder Metallurgy – Pressing and sintering to create lightweight, high-strength structural parts for aerospace applications.

Specifications of TA7 Powder

TA7 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.

Morphology: Near-spherical powder shape provides optimal flow and packing density.

Purity: From commercial purity to ultra high purity levels based on impurity limits and process requirements.

Oxygen Content: Levels maintained below 2000 ppm for most applications.

Flow Rate: Powder customized for excellent flow rates above 25 s/50 g.

Storage and Handling of TA7 Powder

TA7 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 TA7 Powder

Key quality control tests performed on TA7 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 TA7 and Inconel 718 Powders

TA7 and Inconel 718 powders compared:

Parameter TA7 Inconel 718
Density 3.7-4.0 g/cm3 8.2 g/cm3
High temperature strength Comparable Comparable
Oxidation resistance Better Good
Cost Higher Lower
Workability Poor Excellent
Applications Aerospace components Aerospace, automotive
Availability Low Readily available

TA7 offers weight savings over Inconel 718. But workability is poor and availability is lower for titanium aluminide powder.
