Factors affecting strength of dissimilar TiAl/Ni–Si–B/Ni-based superalloy brazed joint

This paper addresses the process-microstructure-strength correlation during dissimilar brazing of TiAl alloy to IN738 Ni-based superalloy using Ni–4Si–3.2B filler metal. The solid/liquid reactions, solidification phenomena, and solid-state phenomena are analyzed. The thickness of the athermal solidi...
