- Micrograph no
- Brief description
- Fibre fracture in a metal matrix composite
- alloy , alumina , composite material , fibre , fracture , infiltration, metal, MMC, preform, reinforcement
- Fracture, Metal or alloy
- Commercial purity (99.5%)
- Standard codes
- Commercial purity (99.5%) aluminium has been atomised, thoroughly mixed with alumina reinforcement fibres and then extruded.
- Metal matrix composites (MMCs) offer high specific stiffness which can be retained to high temperatures. This makes them suitable for applications in the aerospace industry. They also offer controlled (or zero) thermal expansion coefficients, good wear resistance and good impact properties.
- Sample preparation
- Scanning electron microscopy (SEM)
- Length bar
- 4 μm
- Further information
- Fracture in one fibre has promoted fracture in the adjacent fibres.
