Powdered Metals in Additive Manufacturing (AM) and Powder Metallurgy (PM)
RJ Lee Group offers an extensive array of analytical methods and techniques appropriate to each powdered metals sample, whether virgin and recycled feedstock material is used.
- Powdered Metals (Laser or Electron Beam Powder Bed Fusion, or Directed Energy Deposition)
- Composition
- Bulk chemistry
- Particle by Particle (PxP) using computer-controlled SEM
- Dimensions
- Particle size distribution (PSD)
- Shape factors (aspect ratio, roundness, roughness) per ASTM F1877
- Surface detail captured in PxP images
- Contaminants
- Cross-Contamination (particles of undesired alloy present in subject alloy)
- Non-Metallic / Ceramic / Oxide / Carbonaceous Contaminants
- Composition

Characterization for All Types of Additive Manufacturing / 3D Printing
