چکیده انگلیسی
Planetary ball mill PM 400 from Retsch (with different milling times for Ω = 400 rpm, Ï = 800 rpm) and P4 vario ball mill from Fritsch (with different milling conditions (Ω/Ï), Ω and Ï being the disc and the vial rotation speeds, respectively) are used for obtaining nanocrystalline Fe-10wt% Ni. The structure and magnetic properties are studied by using X-ray diffraction, SEM and hysteresis measurements, respectively. The bcc-Fe(Ni) phase formation is identified by X-ray diffraction. The higher the shock power and the higher milling time are, the larger the bcc lattice parameter and the lower the grain size. The highest value of the coercivity is 1600 A/m for Fe-10 wt.%Ni (with shock mode (424 rpm/100 rpm) after 36 h of milling), while the lowest value is 189 A/m for (400 rpm/800 rpm) after 72 h of milling. The milling performed in the friction mode has been found to lead the formation of alloys exhibiting a soft magnetic behavior for nanocrystalline Fe-10%Ni.
