Abstract
Bu çalışmada, (FeCo)90Ni10, (FeCo)70Ni30 ve (FeCo)50Ni50 (% ağ.) toz alaşımları, 5 saatlik mekanik alaşımla işlemi sonucunda nanokristal yapıda üretilmiştir. Elde edilen alaşımların yapısal ve morfolojik incelemeleri X-ışını kırınım yöntemi (XRD) ve taramalı elektron mikroskobu/ enerji dağılımlı X-ışını spektroskopisi (SEM/EDS) ile analiz edilmiştir. Alaşımların XRD analizi sonucunda yüzey merkezli kübik ve hacim merkezli kübik katı çözelti fazları tespit edilmiştir. (FeCo)90Ni10, (FeCo)70Ni30 ve (FeCo)50Ni50 alaşımlarının kristalit boyutları 5 saatlik öğütme sonucunda sırasıyla 24.7, 23.2 ve 16.5 nm olarak, örgü gerinimleri ise sırasıyla % 0.308, % 0.404 ve % 0.563 olarak hesaplanmıştır. Titreşimli Örnek Manyetometresi (VSM) sonuçları, örneklerin düşük koerzivite ve görece yüksek doyum mıknatıslanması ile yumuşak manyetik özelliğe sahip olduğunu göstermektedir. (FeCo)70Ni30 nanokristal alaşımının sahip olduğu 127 emu/g değerindeki yüksek doyum mıknatıslanması ve 18 Oe’lik düşük koerzivitesi, alaşımın özelilkle güç üretimi, dağıtımı ve çevrimi gibi yumuşak manyetik özellik gerektiren uygulamalar için iyi bir aday olduğunu göstermektedir.

Abstract
In this study, (FeCo)90Ni10, (FeCo)70Ni30 ve (FeCo)50Ni50 (% wt.) nanocrystalline powder alloys are produced by mechanical alloying, where milling duration set for 5 h. The structural and morphological properties of the as-produced alloys are performed using X-ray diffraction (XRD) and scanning electron microscopy/ energy dispersive spectroscopy (SEM/EDS). As a results of the XRD analysis of the alloys, fcc and bcc phases were determined. After 5 h of milling durations the crystallite sizes lattice strain of the (FeCo)90Ni10, (FeCo)70Ni30 ve (FeCo)50Ni50 alloys are calculated as 24.7, 23.2 ve 16.5 nm and 0.308 %, 0.404 % ve 0.563 %, respectively. Vibrating Sample Magnetometer (VSM) results show that the samples have soft magnetic properties with low coercivity and relatively high saturation magnetization. The high saturation magnetization of 127 emu/g and low coercivity of 18 Oe of the (FeCo)70Ni30 nanocrystalline alloy show that the alloy is a good candidate for applications that require soft magnetic properties, especially for power generation, distribution, and conversion.
