Abstract

In this study, amorphous/nanocrystalline Fe70Ti10B20 (at.%) alloys were synthesized byusing elemental Fe, Ti and B powders under argon gas atmosphere via mechanical alloyingmethod. The powders were ball milled at 20:1 ball to powder ratio and 500 rpm rotatingspeed up to 70 h. The phase and morphological properties of the synthesized powderswere examined by using X-Ray diffractometer and scanning electron microscopy withenergy-dispersive X-ray spectroscopy (SEM/EDX). The magnetic properties of powderswere determined by vibrating sample magnetometer (VSM) at room temperature in therange of 0-20 kOe. It is determined that after 2.5 h of milling Ti and B are started todissolve in Fe lattice and Fe(TiB) solid solutions formed. XRD analysis revealed that theamorphous structures were formed after 30 h of milling and the crystallite size and latticestrain were found around 8.2 nm and %1.16, respectively. SEM images indicated that theparticles were mostly agglomerated and the particles size distribution was in the rangeof 10-48 μm. Magnetic measurements revealed that after 70 h of milling, the saturationmagnetization (Ms) and the coercivity (Hc) reached about 94 emu/g and 117 Oe.
