Micrograph 732 and full record

- Micrograph no
- 732
- Brief description
- Magnesium alloy
- Keywords
- magnesium
- Categories
- Metal or alloy
- System
- Mg-Zn
- Composition
- Mg 94.05, Zn 5.62, Zr 0.19, Ce 0.10, Nd 0.03 (wt%) (RZ5 Alloy)
- Standard codes
- Reaction
- Processing
- Tensile test at 300°C.
- Applications
- RZ5 magnesium alloy is commonly used for wheels in both Formula One and Super-bike competitions because of its high strength to weight ratio.
- Sample preparation
- Standard polishing techniques
- Technique
- Scanning electron microscopy (SEM) in backscattered electron imaging (BEI) mode
- Length bar
- 200 μm
- Further information
- This micrograph shows the ductility of magnesium under tensile loading, manifested by elongated grains parallel to the applied loading. The zinc rich grain boundary phase is more brittle and at distances from the fracture surface shows cracking and formation of micro-voids.
