چکیده مقاله:
This paper addresses simultaneously the effects of standard solution treatment on the microstructure and mechanical properties of IN-738LC superalloy bonded by transient liquid phase (TLP) using Ni-BNi-9 amorphous filler metal. TLP bonding was carried out at the bonding temperature of 1120 °C for 45 min and led to the formation of a nickel proeutectic solid-solution phase (γ) in the joint. The results revealed that after the standard heat treatment the microstructure of the bond and base metal is completely blended together, and γ' precipitates in the joint are similar to those in the base metal. Mechanical test results indicated high joint shear strength of the sample post-bond heat-treated, approximately 99% of the base metal.
