Özet:

 In this study, equimolar nanocrystalline Fe-Si-Cu at. and Fe-Si-Nb at. alloys were synthesized under an Argon atmosphere by a mechanical alloying method. Experimental parameters were determined as 350 rpm, 10:1 BPR, 120 hours. Phase structures of the synthesized alloys were investigated by X-Ray diffractometry, morphology and elemental analyzes were investigated by SEM-EDS, and magnetic properties were investigated by vibrating sample magnetometer VSM technique at room temperature. The crystallite size of the Fe-Si-Cu alloy was found to be 102.3, 22.5, 15.9 and 8.6 nm at the beginning of grinding, after 30, 60 and 120 hours grinding, respectively, and the lattice strains were 0.164, 0.510, 0.672 and 1.165, while the Fe-Si-Cu alloy For the Nb alloy, the crystallite sizes were calculated as 140.8, 42.9, 16.8 and 7.8 nm, and the lattice strains were calculated as 0.134, 0.301, 0.639 and 1.271. According to the magnetism results, the saturation magnetization Ms of the Fe-Si-Cu at. alloy was found to be 3146 emug, while the saturation magnetization of the Fe-Si-Nb at. alloy was found to be 8.91 emug. It was determined that Nb addition to the Fe-Si alloy system caused an increase in the coercivity values.

 Bu çalışmada mekanik alaşımlama yöntemi ile Argon atmosferi altında eş molar nanokristal Fe-Si-Cu at. ve Fe-Si-Nb at. alaşımları sentezlenmiştir. Deney parametreleri 350 rpm, 10:1 BPR, 120 saat olarak belirlenmiştir. Sentezlenen alaşımların faz yapıları X-Işınları difraktometresi ile, morfoloji ve elementel analizleri SEM-EDS ile, manyetik özellikleri ise oda sıcaklığında titreşimli örnek manyetometresi VSM tekniği ile araştırılmıştır. Fe-Si-Cu alaşımının kristalit boyutu öğütme başlangıcı, 30, 60 ve 120 saat öğütme sonrası sırasıyla 102.3, 22.5, 15.9 ve 8.6 nm, örgü gerinimleri ise  0.164,  0.510, 0.672 ve 1.165 olarak bulunurken, Fe-Si-Nb alaşımı için ise kristalit boyutlar 140.8, 42.9, 16.8 ve 7.8 nm, örgü gerinimleri ise  0.134,  0.301,  0.639 ve  1.271 olarak hesaplanmıştır. Manyetizma sonuçlarına göre, Fe-Si-Cu at. alaşımının doyum manyetizasyonu Ms 3146 emug olarak bulunurken, Fe-Si-Nb at. alaşımının doyum manyetizasyonu 8.91 emug olarak bulunmuştur. Fe-Si alaşım sistemine Nb katkısının kuarzivite değerlerinde artışa sebep olduğu belirlenmiştir.
