Abstract

Two different filler metals were used for vacuum brazing of NIMONIC 105 similar joints. At first, the specimen was brazed using BNi-2 as filler. The optimized parameters were brazing time and temperature of 7 min and 1200°C, respectively. Then, the innovative approach of adding tungsten to the braze filler was adopted to improve the metallurgical properties of the joints. The formation of intermetallic and eutectic phases was investigated by back-scattered electron (BSE) imaging, energy dispersive X-ray spectroscopy (EDS), X-ray diffraction (XRD), and hardness testing. The investigation confirmed that, unlike the bulky brittle phases (SiCr3, Ni2B, Cr2B, and NiSi), and network or eutectic phases found in the specimen brazed using BNi-2 as filler, a W-rich filler (BNi-10) creates fine precipitates (CrSi2, Cr2B) that have minimal impact on the properties of the joint. Microhardness evaluation indicated that using the BNi-10 filler resulted in more uniform hardness profiles across the joint. The shear strength of brazed joints increased significantly from 81.8 MPa to 88.1 MPa with the addition of tungsten. Lack of Ni2B and NiSi formation resulted in a high ductility of 17.1% in the specimen brazed via BNi-10 when compared with 10.95% in the specimen brazed via BNi-2.
