Abstract

We investigated a soft magnetic Fe(87-x-y)CoxTi7Zr6By (x = 25, 30, 35 at.%, and y = 2, 4 at.%) alloy system. The Fe-based amorphous materials have been studied because of excellent soft magnetic properties: high saturation magnetization and low coercivity. Especially, the Fe-Co system has the high saturation magnetization in comparison to Fe-only and Co-only cases. In this research, we used an X-ray diffractometer, differential scanning calorimeter, vibrating sample magnetometer and high-temperature vibrating sample magnetometer in order to observe the properties of the Fe-Co-Ti-Zr-B alloy system. One of the alloys showed the saturation magnetization of 1.67 T which is same as the highest value of Fe-based amorphous alloys. Furthermore, nanoindentation was performed to study the mechanical properties of this system. The highest and lowest values of nanoindentation hardness were 10.1 GPa and 8.2 GPa, respectively.
