Table 2 Changes of structures across the multiple scales in the magnetic-field-assisted solidification, their benefit for creep properties, and from a certain effect of the magnetic field.
Structures across multiple scales | Changes in magnetic-field-assisted solidification | Benefits for creep property | From what effect of magnetic field |
|---|---|---|---|
Single-crystal integrity | Destroy | No | TEMF |
Primary dendrite-arm spacing | Increase | No | MHD |
Macrosegregation | Decrease | Yes | MHD |
Microsegragation | Decrease | Yes | MHD |
Element partition difference in γ/γ′ phases | Decrease | Yes | Related to macro- and micro-segregation |
Lattice misfit of γ/γ′ phases | Decrease | Yes | Related to macro- and micro-segregation |
γ′ size, carbide and eutectic contents | Decrease | Yes | Related to macro- and micro-segregation |
