Description

Based on the composition of the interdendritic Zr-rich melt in the later stages of solidification of Zr-containing superalloys, a Ni-10Co-8Cr-4W-13Zr (wt.%) alloy was selected as an interlayer alloy for brazing and transient-liquid-phase (TLP) bonding of single crystal superalloys. All the elements in the interlayer alloy are beneficial to the single crystal superalloys. Using the above alloy, bonds free of brittle phases in the single crystal superalloy have been obtained by isothermal solidification at 1,270 C for 48 hours. In the present work, the microstructural characteristics of the interlayer alloy and the phase relationship in the bond during brazing and TLP processes are reported
