In this study, we investigated the effect of Fe-Ni-based superalloys on the structural and mechanical properties of alloying elements. After producing the Fe-40%Ni-2%X (X=Mn, Si) superalloys, we heat treated them for 24 hours at 1150°C and 1200°C, respectively. We examined their structural and mechanical properties by using optical microscope (OM) and scanning electron microscope (SEM) methods, respectively, under current conditions. Mechanical properties were determined by Vickers microhardness (VS) and stress-strain methods. OM and SEM images showed that these two samples were austenite at room temperature. VS measurements revealed that the mean hardness value (147.2 VSD) of the Fe-40%Ni-2%Si sample was greater than the mean hardness value (119.2 VSD) of the Fe-40%Ni-2%Mn sample. In the stress-strain measurements, while it was determined that 6 kN load should be applied to the Fe-40%Ni-2Mn sample in austenite structure for plastic deformation, Fe-40%Ni-2%Si sample in austenite structure showed a flexible behavior despite the application of 100 kN load.

Bu çalışmada, Fe-Ni bazlı süperalaşımların alaşımlama elementlerinin yapısal ve mekanik özellikleri üzerine etkisini inceledik. Fe-%40Ni-%2X (X=Mn, Si) süperalaşımlarını ürettikten sonra sıra ile 1150 C ve 1200 C’de 24 saat onları ısıl işleme maruz bıraktık. Yapısal ve mekanik özelliklerini mevcut şartlarda sırayla optik mikroskop (OM) ve taramalı elektron mikroskop (SEM) yöntemleriyle inceledik. Mekanik özellikler ise Vickers mikrosertlik (VS) ve zor-zorlanma yöntemleriyle belirlenmiştir. OM ve SEM görüntüleri bu iki numunenin oda sıcaklığında austenite yapıda olduğunu göstermiştir. VS ölçümleri Fe-%40Ni-%2Si numunesinin ortalama sertlik değerinin (147.2 VSD) Fe-%40Ni-%2Mn numunesinin ortalama sertlik değerinden (119.2 VSD) daha büyük olduğunu ortaya çıkarmıştır. Zor-zorlanma ölçümlerinde, austenite yapıdaki Fe-%40Ni-%2Mn numunesine plastik deformasyon için 6 kN’luk yük uygulanması gerektiği tesbit edilmişken, Fe-%40Ni-%2Si numunesi 100 kN’luk yük uygulanmasına rağmen esnek bir davranış sergilemiştir.
