摘 要: | The effects of plastic deformation on the magnetic properties of austenite structure in an Fe40%Ni2%Mn alloy is investigated by using Mssbauer spectroscopy and Differential Scanning Calorimetry (DSC) techniques The morphology of the alloy has been obtained by using Scanning Electron Microscopy (SEM). The magnetic behaviour of austenite state is ferromagnetic. After plastic deformation, a mixed magnetic structure including both paramagnetic and ferromagnetic states has been obtained at the room temperature. The volume fraction changes, the effective hyperfine fields of the ferromagnetic austenite phase and isomery shift values have also been determined by Mssbauer spectroscopy. The Curie point (TC) and the Neel temperature (TN) have been investigated by means of DSC system for nondeformed and deformed FeNiMn alloy. The plastic deformation of the alloy reduces the TN and enhances the paramagnetic character of austenitic FeNiMn alloy.
