Fe-30%Ni-%2.6Mo-X%Co Alaşımlarının Martensitik Faz Dönüşümünün ve Manyetik Özelliklerinin Araştırılması

In this study, the microstructure of thermal effective martensitic phase transformation observed in Fe-30wt.%Ni-2.6wt.%Mo-Xwt.%Co (X = 0.8, 1.8) alloy was investigated morphologically and crystallographically by using Scanning Electron Microscopy (SEM) Transmission (TEM). SEM studies, it that morphology martensite changed from lath lenticular structure to massive with addition Co alloy. this, nano formation also as another effect (figure 2c, d). Properties martensite, electron diffraction pattern austenite structures were given TEM studies. According Differential Calorimetry (DSC) analysis, determined temperature (Ms) significantly increased increase amount alloys. Also, Mössbauer spectroscopy, shown magnetic order accordingly.
