상세내용 ABSTRACT
Fe-based amorphous ribbons with excellent soft magnetic properties
and mechanical properties were prepared in the Fe–Si–P ternary
system. Enhanced soft magnetic properties could be achieved through
annealing treatment of the ribbons for 1 h at 325 °C, which is far below
the glass transition temperatures (462–474 °C). Icosahedral mediumrange
ordering with a size range of around 2 nm occurred throughout
the amorphous matrix during the low-temperature annealing
treatment. The annealed ribbons exhibited improved magnetic
saturation of over 185 emu/g while maintaining good mechanical
flexibility. During icosahedral ordering, the distance between the Fe
atoms and the coordination number within the amorphous ribbon
can be optimised for achieving high magnetic saturation. However,
nanocrystallisation of the SiP and Fe2P transition phases embedded
within the amorphous matrix occurred after the annealing treatment
for 1 h at 385 °C, which caused deterioration of the soft magnetic
properties and mechanical flexibility of the ribbons. Therefore, the
combination of high magnetic saturation and mechanical flexibility of
the amorphous ribbons could be optimised through low-temperature
annealing treatment without any nanocrystallisation.
