- Brief description
- Ni-Superalloy
- Keywords
- creep
, nickel, single crystal - Categories
- Metal or alloy
- System
- Ni-X
- Composition
- Ni, Al, Re, W, Ta, Cr, Co, Ru (Ni-Superalloy)
- Standard codes

- Solution heat treated, creep test
- Applications
- The single crystal superalloy can undergo microstructural changes when it’s stressed at high temperature, the phenomena is called "rafting", which can be good for high temperature (above 1050°C) and low stress (100 MPa) conditions.
