Micrograph 769 and full record
- Micrograph no
- 769
- Brief description
- Bi 90, Sn 10 (wt%)
- Keywords
- alloy
, bismuth, metal, tin - Categories
- Metal or alloy
- System
- Bi-Sn
- Composition
- Bi 90, Sn 10 (wt%)
- Standard codes
- Reaction
- Processing
- Small casting in alumina crucible - air cooled.
- Applications
- Educational alloy - low melting point allows easy and safe use for students.
- Sample preparation
- Standard polishing techniques.
- Technique
- Scanning electron microscopy (SEM) in secondary electron imaging (SEI) mode
- Length bar
- 100 μm
- Further information
- Some small scale ordering is apparent, with the pale areas almost pure bismuth, and the darker areas having near eutectic composition, and showing lamellae similar to those in micrograph 763.
