Study on the crystal structure and particle appearance of the melt-spun Cu-Co-Ni alloys
The Cu95-xCoxNi5 (x=0, 7, 13, 15, 19, 25, 31) alloy ribbons were prepared with the method of melt-spun. The morphology of the ribbons and the content ratio of the Co/Ni/Cu in the granule and its background region were investigated using Field Emission-Scanning Electron Microscope (SEM) with energy-dispersive spectrometry (EDS). The crystal structure of the ribbons was investigated using the X-ray Diffraction (XRD). We found that the samples possess the fcc structure, and its crystal lattice constant was larger than that of Ni sample and a little smaller than that of Cu. There are many granules on the surface of the sample, and the diameter of most of granules are about 10～30 nm. We found the Co content that on the granule is higher than the other areas that have no granules.
