2. Advantages vs. International Standards
This TA15 titanium alloy powder fully complies with GB/T (Chinese standard), while exceeding key specifications:
- ✅ Precise Al control (5.5–7.1%, target ~6.5%): Ensures high α-phase stability and superior high-temperature strength;
- ✅ Ultra-low oxygen content (O ≤ 0.12%) — better than GB limit of ≤0.15%, significantly reducing embrittlement risk;
- ✅ High sphericity (≥0.9) & excellent flowability (≤35 s/50g): Guarantees uniform powder recoating in SLM/EBM, minimizing spatter and lack-of-fusion defects;
- ✅ High apparent density (≥2.4 g/cm³) and tap density (≥2.8 g/cm³): Approaching theoretical maximum (~3.0 g/cm³), enabling >99.5% relative density in printed parts;
- ✅ Outstanding mechanical properties: UTS ≥1050 MPa at RT (vs. GB min. 930 MPa); elongation ≥15.0% at 600°C — demonstrating exceptional high-temperature ductility and creep resistance;
- ✅ Optimized particle size distribution (D₅₀ = 30–40 μm): Engineered for industrial LPBF systems, balancing laser absorption and melt pool stability.
In summary, this TA15 powder meets the stringent requirements of aerospace hot-section components and is ideal for additive manufacturing of complex thin-walled structures, serving as a reliable alternative to forged parts.
3. Application of TA15 Powder in Additive Manufacturing
TA15 (Ti-6.5Al-1Mo-1V-2Zr), is widely adopted in aerospace for its exceptional high-temperature strength (500–600°C), good weldability, and moderate workability; in additive manufacturing, its powder has been successfully used to fabricate high-pressure compressor blades via SLM or EBM — enabling topology-optimized lightweight designs unattainable by forging, while retaining >95% of the high-temperature mechanical performance. After heat treatment (e.g., β-annealing + aging), the printed parts exhibit superior microstructural homogeneity and lower residual stress compared to castings, providing a robust raw material solution.
