In this work, the CuAlFe and CuAlFeNi (wt. %) alloys were used. This study, the phase structure, crystallography and magnetic characterization of the two alloys are investigated depending on the Ni element. The Scanning Electron Microscope (SEM) and X-ray Diffractometry (XRD) were used to observe the changes in the microstructure after the addition of element Ni. The magnetic behavior of the alloys was characterized by Physical Properties Measurement System (PPMS) instrument. SEM results revealed that Kappa phases were formed in both alloys. While the saturation magnetization of CuAlFe and CuAlFeNi is ~ 8.6 and ~ 6.1 emu/g at 300 K, the coercivity field values of CuAlFe and CuAlFeNi are approximately 3262.67 and 1750.70 A/m, respectively. Thus magnetic results showed that the element Ni caused a difference in the magnetic parameters. Furthermore, both alloys exhibited soft ferromagnetic properties. The results indicate that the worked alloys could be used in soft ferromagnetic applications.

Bu çalışmada CuAlFe ve CuAlFeNi (% ağırlık) alaşımları kullanılmıştır. Çalışmada; iki alaşım için faz yapısı, kristalografisi ve manyetik karakterizasyonu Ni elementine bağlı olarak incelenmiştir. Nikel elementinin eklenmesinden sonra mikroyapıdaki değişimleri gözlemlemek için Taramalı Elektron Mikroskobu (SEM) ve X-ışını Difraktometrisi (XRD) kullanılmıştır. Alaşımların manyetik davranışları, Fiziksel Özellik Ölçüm Sistemi (PPMS) cihazı ile karakterize edilmiştir. SEM sonuçları, her iki alaşımda da Kappa fazlarının oluştuğunu ortaya koymuştur. CuAlFe ve CuAlFeNi' nin doygunluk mıknatıslanması 300 K' de ~ 8.6 ve ~ 6.1 emu/g iken, CuAlFe ve CuAlFeNi' nin zorlayıcı alan değerleri sırasıyla ~ 3262.67 ve ~ 1750.70 A/m olarak bulunmuştur. Dolayısıyla manyetik sonuçlar, Ni elementinin manyetik parametrelerde bir farka neden olduğunu göstermiştir. Ayrıca, her iki alaşımda yumuşak ferromanyetik özellikler sergilemiştir. Elde edilen sonuçlar, çalışılan alaşımların yumuşak ferromanyetik uygulamalarda kullanılabileceğini göstermektedir.
