Abstract
Comparative investigations were carried out to study strength of high-temperature vacuum brazed joints on heat-resistant nickel alloy Inconel 718, made by using filler metals of the Pd-Ni-Cr-Si, Pd-Ni-Co-Cr-Si and Pd-Ni-Cr-B systems and experimental filler metal of the Pd-Ni-Cr-Ge system. The experimental filler metal was shown to have a high potential for ensuring specified short- and long-time strength of the brazed joints.
