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.eninfo:eu-repo/semantics/closedAccessmossbauer spectroscopyscanning electron microscopydentriteferromagnetic austeniteArticle14432733010.1016/S1005-8850(07)60064-42-s2.0-34547098132N/AWOS:000249473400008Q3
