The main scope of this study investigated the occurrence liquation cracking in heat-affected zone (HAZ) IN738 superalloy weld, is widely used gas turbine blades land-based power plants. Microstructural examinations showed considerable amounts γ’ uniformly precipitated γ matrix. Electron probe microanalysis (EPMA) maps γ-γ’ colonies were rich Al and Ti, but lean other alloy elements. Moreover, metal carbides (MC), fine borides (M3B2 M5B3), η-Ni3Ti, σ (Cr-Co) lamellar Ni7Zr2 intermetallic...
Infrared vacuum brazing of CoCrFeMnNi high entropy alloy (HEA) using BNi-2 and MBF601 fillers has been investigated. Both brazes show poor wettability at temperatures only 20 °C above their liquidus temperatures. However, the on HEA is greatly improved with increasing test temperatures, 50 The brazed joints are dominated by Ni-rich matrix huge CrB a few tiny boride precipitates. Average shear strengths increase temperature and/or time, fracture location changes from blocky in zone to grain...
