Abstract:

 





In
this study, amorphous/nanocrystalline Fe70Ti10B20
(at.%) alloys were synthesized by
using elemental Fe, Ti and B powders under argon gas atmosphere via mechanical
alloying method. The powders were ball milled at 20:1 ball-to-powder ratio and
500 rpm rotating speed up to 70 h. The phase and morphological properties of the
synthesized powders were examined by using X-Ray diffractometer and scanning
electron microscope with energy-dispersive X-ray spectroscope (SEM/EDX). The magnetic
properties of powders were determined by vibrating sample magnetometer (VSM) at
room temperature in the range of 0-20 kOe. It is determined that after 2.5 h of
milling, Ti and B are started to dissolve in Fe lattice and Fe(TiB) solid
solutions formed. XRD analysis revealed that the amorphous structures were
formed after 30h of milling and the crystallite size and lattice strain were
found ~ 8.2 nm and 1.16%, respectively. SEM images indicated that the particles
were mostly agglomerated and the particles size distribution was in the range
of 10-48 μm. Magnetic measurements revealed that after 70 h of milling, the
saturation magnetization (Ms) and the coercivity (Hc) was
about 94 emu/g and 117 Oe.
