Additional FAQs on Titanio TC4
1) Can Titanio TC4 be 3D-printed for end-use parts?
Yes. Ti-6Al-4V (Titanio TC4) is the most widely used titanium powder in metal additive manufacturing (LPBF/SLM, EBM, DED). It achieves 94–99.5% relative density with proper process parameters and post-heat treatment, suitable for aerospace brackets, medical implants, and heat-exchangers.
2) What are optimal heat treatments for 3D-printed Titanio TC4?
Typical sequences include stress-relief (650–750°C, 1–3 h, Ar/vacuum), hot isostatic pressing (HIP: ~920–930°C, 100–120 MPa, 2–4 h), and aging as needed. HIP closes internal porosity and improves fatigue life significantly.
3) How does surface finish impact fatigue in Titanio TC4?
Surface roughness strongly affects high-cycle fatigue. Shot peening, micro-blasting, chemical milling, electropolishing, and laser polishing can boost fatigue strength by 20–60% versus as-printed or as-machined surfaces.
