Design and optimization of BNi-2+CoCrNi composite interlayer for GH5188 superalloy TLP bonding

Transient liquid phase (TLP) bonding of GH5188 superalloy was achieved using composite interlayers of BNi-2 and CoCrNi medium-entropy alloy (MEA) powders at 1190 °C/60 min. The critical role of CoCrNi MEA content was systematically investigated. At 0.5–1 wt.%, CrB precipitates dominated the joint mi...
