Materials Processing & Analysis

At Fraunhofer IFAM Dresden, various processing technologies are readily available to cover the whole fabrication route from the raw materials to hydride composites with application-specific properties:

• Induction melting
• Rapid solidification (e.g. melt spinning, melt extraction)
• Milling (e.g. high-energy ball-milling, vibrating cup milling)
• Powder Processing (e.g. mixing, blending, compaction)

For the analysis of hydrogen-specific materials properties a broad spectrum of methods is available:

• Thermal analysis:
  - High-pressure TGA (under H₂ pressures up to 350 bar and temperatures up to 400 °C)
  - Sievert’s apparatus (under H₂ pressures up to 200 bar and temperatures up to 500 °C)
  - High-pressure DSC (under H₂ pressures up to 150 bar and temperatures up to 600 °C)
  - Thermal conductivity analysis
• Gas permeability analysis
• Elemental analysis (H, N, O)
• ICP-OES for multi-elemental analysis
• X-ray diffractometry
• Electron and optical microscopy
