Characterization of immiscible Ni78Ag2P20 alloy and formation of amorphous/crystalline composite

This paper presents characterization of the ternary Ni78Ag2P20 alloy that was arc-melt in argon protective atmosphere and melt spun in helium. The microstructure of the arc-melt droplet was investigated in scanning electron microscope with EDS. The microstructural studies of the melt-spun alloy was made using light microscope, transmission electron microscope and X-ray diffraction. A tendency for separation of the alloy was found and the phases were identified. The mechanical properties were evaluated with use of micro-hardness measurements and the results compared with the available data.
