- Abstract:
-
The kinetics of directional γ' coarsening, known as rafting, are examined in the nickel based single crystal superalloy CMSX-4. Electron microscopy and image analysis are used to characterise heat treated specimens, prestrained in creep to a plastic strain beyond the threshold required to initiate rafting. The kinetics of rafting are found to be sensitive to the presence of microsegregation from casting, incompletely removed by the heat treatment process; thus the dendritic regions raft appre...
