Microstructure Evolution and Mechanical Properties of TLP Bonded Joint of IN-738LC Superalloy using MBF-20 Amorphous Foil
In this research, the TLP bonding of IN-738LC superalloy was investigated using MBF-20 amorphous foil produced by melt spinning process. The bonding process was carried out at 1035-1080°C for 30-60 min under the vacuum atmosphere. Microstructural investigations showed that the eutectic phase...

| description | In this research, the TLP bonding of IN-738LC superalloy was investigated using MBF-20 amorphous foil produced by melt spinning process. The bonding process was carried out at 1035-1080°C for 30-60 min under the vacuum atmosphere. Microstructural investigations showed that the eutectic phases formed in non-isothermal solidified zone (ASZ) are consised of secondary phase borieds rich in nickel, chromium and nickel silicides. Nickel silicide fine precipitates are formed within γ solid solution via solid state precipitation during cooling. The centerline eutectic phases decreased with increase of the bonding time and decrease of amorphous foil thickness. It was found that isothermal solidification was completed when bonding was done at 1055°C for 30 min. However, the isothermal solidification rate decreased with increasing of the bonding temperature up to 1080°C. Unexpectedly, isothermal solidification rate decreased by increasing the tempretarure to 1080°C. The shear strength increased by completing isothermal solidification stage and eliminating brittle secondary phase particles in the centerline of bonding zone. |
