Abstract





Bu
çalışmada nanokristal Co70Si15B15 (at.%) toz
alaşımları, mekanik alaşımlama (MA) tekniği ile farklı öğütme sürelerinde
üretilmiştir. Öğütme süresince alaşımların yapısal değişimleri, parçacık
morfolojisi, termal kararlılıkları ve manyetik özellikleri incelenmiştir. X-ışını
difraksiyonu (XRD) sonuçları, elementel tozların birbirleri ile olan reaksiyonu
sonucu nanokristal Co(Si,B) katı çözelti fazını oluşturduğunu göstermiştir.
Taramalı elektron mikroskobu (SEM) analizlerinden morfolojinin alaşımlama
boyunca değiştiği ve parçacık boyutunun öğütmenin ilk safhalarında arttığı,
daha sonra küçüldüğü anlaşılmıştır. Alaşımların yapısal durumuna bağlı olarak
görülen ekzotermik reaksiyonun aktivasyon enerjisi 128 ± 3 kJ/mol olarak
hesaplanmıştır. Manyetik sonuçlar, artan öğütme süresiyle hem doyum
manyetizasyonunun (Ms) hem de koersivitenin (Hc)
azaldığını göstermiştir.

Abstract










In
this research, nanocrystalline Co70Si15B15
(at.%) powder alloys were prepared by mechanical alloying (MA) technique at
various milling times. Their structural changes, particles morphology, thermal
stability and magnetic properties through the milling process were
investigated. The X-ray diffraction (XRD) results showed that reaction of the
elemental powders mixture resulted in the formation of the nanocrystalline
Co(Si,B) solid solution phase. According to the scanning electron microscopy
(SEM) analysis, particle morphology was changed during alloying and the
particle size increased initially, then decreased. Depending on the structural
state of the alloys, the apparent activation energy of the exothermic reaction
was calculated as 128 ± 3 kJ/mol. Magnetic results indicated that both
saturation magnetization (Ms) and coercivity (Hc) were
decreased with increasing milling time.
