Özet
The effect of austenitising temperature and cooling rate on the morphology and magnetic properties of martensite in Fe-24-5%Ni-4-5%Si alloy has been studied by means of scanning electron microscopy, Mbssbauer spectroscopy and AC susceptibility. Martensite morphology was found to be closely dependent on the austenitising temperature and cooling rate. The changes in volume fraction of martensite and austenite phases, the internal magnetic field of martensite phase and the isomery shift values have been determined by Mbssbauer spectroscopy. The Mbssbauer study revealed that the martensite volume fractions increased with increasing austenitising temperature and cooling rate. Also internal magnetic field of martensite was decreased by increasing the martensite volume fractions. AC magnetic susceptibility measurements showed that the Neel temperatures T-N and the magnetic susceptibility X increase with increasing austenitising temperatures.
