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.
