چکیده
Recently nanocrystalline magnetic materials have been intensively investigated because of their remarkable properties such as saturation magnetization, coercivity, magnetic ordering temperature and hyperfine magnetic field which significantly differ from those of microcrystalline materials and are sensitive to the structure and microstructure [1]. FeNi alloys are industrially used for high-saturation magnetization and low coercivity applications. The benefits found in these magnetic nanostructured alloys stem from their chemical and structural properties which are important for the magnetic properties [2]. Mechanical alloying (MA) is a powerful technique which allows the preparation of nanostructured FeNi alloys [3,4]. The aim of the present work is first to produce the binary Fe50Ni50 system by high-energy ball alloying technique. The powders were investigated by means of microstructural observations by scanning microscopy and X-ray diffraction. Also Microhardness of the powders were measured.کلیدواژه ها

اطلاعات بیشتر در مورد COI
COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
