Abstract
The mechanical alloying process has been used to prepare nanocrystalline Ni20Co80 alloy from elemental Ni and Co powders in a planetary ball mill under argon atmosphere. Scanning electron microscopy, X-ray diffraction and magnetic measurements were carried out to investigate morphological, structural, microstructural and magnetic properties changes during the milling process. The interdiffusion of Co and Ni leads to a heterogeneous solid solution with Ni-rich and Co-rich environments after 12 h of milling. The end product is a mixture of a highly disordered structure, fcc-Ni(Co), fcc-Co(Ni) and hcp-Co (Ni) phases having different microstructural and structural parameters. The coercivity, Hc, decreases rapidly up to 3 h of milling to about 58.3 Oe and remains constant on further milling. The saturation magnetization, Ms, value of about 126 emu/g is obtained after 48 h of milling.
