چکیده مقاله:
In this study, nanostructured (Fe۸۵Ni۱۵)۱۰۰-xCux (x = ۰, ۰.۵, ۱.۵, ۳ and ۵) powders were synthesized via mechanical alloying process. The obtained phases, microstructure, and magnetic properties of these alloys were studied by X-ray diffraction analysis (XRD), scanning electron microscopy (SEM), and vibration sample magnetometer (VSM). XRD results indicated that after a suitable time of milling, Ni and Cu were homogeneously distributed in the Fe matrix, and (bcc) α-(Fe(Ni-Cu)) solid solution was obtained. It was found that by increasing Cu content in the alloy, work hardening increased, and thus the size of grains decreased while the internal micro-strain increased. Also, morphological observations indicated that the addition of Cu led to the formation of finer particles. Also, VSM analysis showed that the addition of Cu into Fe-Ni alloys lowered Ms. On the other hand, the coercivity increased by increasing copper content up to ۱.۵ at. %.©۲۰۱۹ jourcc.
