- Micrograph no
- 630
- Brief description
- FOAMCARP closed cell aluminium foam
- Keywords
- alloy
, aluminium , aluminium foam, cell , composite foam, composite material , foam , FOAMCARP, metal - Categories
- Foam, Metal or alloy, Metal or alloy composite foam
- System
- Al
- Composition
- Not specified
- Standard codes
- Reaction
- Calcium carbonate is used as a foaming agent
- Processing
- Foaming was instigated by a 10 minute anneal at 650 degrees C
- Applications
- Closed cell aluminium foams are an ultra-light material, with potential structural applications in transport and construction. They may also be used in energy absorbing structures and heat exchangers
- Sample preparation
- Technique
- Photography (no microscope)
- Length bar
- 6 mm
- Further information
- Additions such as SiC are made to molten aluminium or aluminium alloy to modify the melt viscosity and make it suitable for foaming. Calcium carbonate is then added to the melt which is solidified to form a precursor which can be foamed in a controlled manner by a subsequent heat treatment. The resulting foam has a fine and relatively uniform cell structure.
