Abstract:FeCoNiCrZr amorphous ribbons with different Co/Ni mole ratio were prepared by melt-spun method and the amorphous alloys were studied using isothermal heat treatment. X-ray diffraction (XRD) and vibrating sample magnetometer (VSM) were used to study the effects of Co/Ni mole ratio on the crystallization processes and magnetic properties of (Fe0.52Co0.48-xNix)73Cr17Zr10 amorphous ribbons.The results show that when x in the range of 0.06 to 0.30, the ribbons are in an amorphous state. The crystallization process of (Fe0.52Co0.30Ni0.18)73Cr17Zr10 is the same as (Fe0.52Co0.18Ni0.30)73Cr17Zr10:Am→α-Fe(Co)+Am''''→α-Fe(Co)+Cr2Ni3+Fe3Ni2+Cr2Zr+unidentified phase. With increasing Co/Ni mole ratio, the thermal stability of the alloys is enhanced and the precipitation of α-Fe(Co) after annealing is restrained. The changing trends of magnetic properties of the two alloys are the same with increasing annealing temperature. When the annealed temperature is below Tp1, saturation magnetization Ms increases with increasing annealing temperature; when the annealed temperatures is over Tp1, Ms decreases quickly with increasing annealing temperature.
