Özet

The effect of austenitization heat treatment on magnetic properties was examined by means of Mossbauer spectroscopy on an Fe-40wt%Ni-2wt%Mn alloy. The morphology of the alloy was obtained by using scanning electron microscopy (SEM) under different heat treatment conditions. The magnetic behavior of the non heat-treated alloy is ferromagnetic. A mixed magnetic structure including both paramagnetic and ferromagnetic states was obtained at 800 degrees C after 6 and 12 It heat treatments. In addition, the magnetic structure of the heat-treated alloy at 1150 degrees C for 12 It was ferromagnetic. With the volume fraction changing, the effective hyperfine field of the ferromagnetic austenite phase and isomery shift values were also determined by Mossbauer spectroscopy.
