Additional FAQs about Nickel Superalloys for 3D Printing (5)

1) What is the difference between IN718 and Inconel 625 in additive manufacturing?

• IN718 offers higher strength after age hardening and is commonly used for structural hot-section parts. Inconel 625 provides superior corrosion resistance and better weldability, making it favorable for heat exchangers and chemical processing hardware. Both nickel superalloys are widely used in PBF-LB/M.

2) Which AM processes work best for nickel superalloys?

• Powder Bed Fusion (PBF-LB/M and PBF-EB) is most common due to fine feature resolution. Directed Energy Deposition (DED/LMD) is preferred for large repairs and cladding. Binder Jetting is emerging for cost-effective preforms followed by sintering/HIP.

3) How do HIP and heat treatment improve printed nickel superalloy parts?

• Hot Isostatic Pressing (HIP) closes internal porosity, improving fatigue life and creep strength. Subsequent solution and aging cycles restore γ′/γ″ precipitation and optimize creep/rupture properties to match or exceed cast/wrought baselines. See AMS 5383, AMS 5662/5664 for guidance.

4) What powder specifications matter most for print quality?

• High sphericity (>95%), low oxygen content (typically <0.03–0.06 wt% depending on alloy), controlled PSD (15–45 µm for PBF), and consistent flow index (Hall or Carney). Lot-to-lot chemical uniformity is key for repeatable mechanical properties.

5) Are there recyclability limits for nickel superalloy powders in PBF?

• Yes. Typical best practice is ≤3–5 recycles with 20–50% virgin top-up, monitoring oxygen, nitrogen, and morphology. Excess reuse can increase oxygen/nitrogen pickup and satellites, degrading density and surface finish. Implement SPC on O/N and PSD.

2025 Industry Trends for Nickel Superalloys in Additive Manufacturing
