Notes:
The phases formed in the wide-gap region brazed with BNi-3 filler metal powder in IN738superalloy were investigated by electron backscatter diffraction (EBSD). The morphology andchemical composition of the phase were investigated by field emission scanning electron microscopy(FESEM) and Auger electron spectroscopy (AES). The wide-gap region brazed with BNi-3 fillermetal had a microstructure consisting of primary Ni3B, binary eutectic of Ni3B-Ni solid solution andternary eutectic of Ni3B-Ni-Ni3Si structure. EBSD pattern analysis revealed that the Ni3B hadorthorhombic structure with lattice parameter of a=0.439, b=0.522 and c=0.662 nm, and the Ni3Siphase had cubic structure with lattice parameter of a=0.350 nm
