Abstract:Processing and formation of Ag–Cu–Zn–Sn filler metals with high Sn content are difficult owing to their high brittleness. A composite flux-cored silver (Ag) filler metal of a CuSn + XB alloy powder was designed using the principle of in situ synthesis. Copper–Copper (Cu–Cu) joints were obtained using a novel Ag-based filler metal (at B contents of 0, 2, and 3%). The microstructure and evolution of the mechanical properties of the Cu–Cu brazed joints were studied by field emission scanning electron microscopy, … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
