Abstract
Microstructure and tensile strength of the Ag–Cu alloy filaments produced by glass-coated melt spinning are investigated. As the filament is formed by rapid quenching from liquid state with the drawing process, the Ag10Cu90 and Ag80Cu20 filaments consist of a single solid solution phase and a metastable phase is observed in the Ag20Cu80 filament.
The tensile behaviour of the filament consisted of a single solid solution is the similar to pure metallic filaments and plastic deformation is observed.
The Ag30Cu70 and Ag70Cu30 filaments characterized by the coarse rod type eutectic texture are a brittle material and have a low tensile strength. It is apparent that there is a size effect on the strength of the other filaments. A high strength of the order of 103 MPa is observed in the filaments with a small diameter of 2 μm.
