چکیده مقاله
In the present study, the effect of bonding time on the microstructure and mechanical properties of Hastelloy C276 and 316 austenitic stainless steel was investigated by the Transient Liquid Phase bonding method the joining process was carried out at 1150 ◦C for 5 and 30 minutes using an BNi 2 interlayer An optical microscope and a scanning electron microscope equipped with an elemental analysis system were used to evaluate the microstructure Vickers hardness test and shear strength test have been used to evaluate the mechanical properties Findings showed that the isothermal solidification zone ISZ and the diffusion affected zone DAZ were detected in the bonding areas of 5 and 30 minutes The 316 austenitic stainless steel DAZ contains borides rich in Fe, Cr,and Ni On the other hand, DAZ Hastelloy C276 alloy contains rich borides of Ni, Cr, Mo, and W Furthermore, as time increased, the hardness and shear strength at the center of the joint increased
