Micrograph 721 and full record
- Micrograph no
- 721
- Brief description
- Ni-Superalloy
- Keywords
- nickel, single crystal
- Categories
- Metal or alloy
- System
- Ni-X
- Composition
- Ni, Al, Re, W, Ta, Cr, Co, Ru (Ni-Superalloy)
- Standard codes
- Reaction
- Processing
- Solution heat treated
- Applications
- The material is in single crystal form for turbine blade application, the operation temperature could easily reach above 1200°C during flight cycles. So, the alloy needs to have good high temperature creep resistance and microstructural stability.
- Sample preparation
- Standard polishing procedure
- Technique
- Field emission gun scanning electron microscopy (FEGSEM) in secondary electron imaging (SEI) mode
- Length bar
- 10 μm
- Further information
- This image shows a secondary electron image of a solutioned Ni-base superalloy. The microstructure consists of g/g’, the darker phase is g’, and the brighter phase is the g.
