Effect of Mo on the magnetic properties of martensitic phase in Fe-Ni-Mo alloys

WOS: 000241414900012The paramagnetic-magnetically ordered transition and the effect of Mo content on the magnetic properties of martensite phase in Fe-30% Ni-x% Mo alloys have been investigated by AC susceptibility and Mossbauer spectroscopy. The results show that martensitic transformation temperature (M(S)) indicates the magnetic transition from paramagnetic to magnetically ordered state. Hyperfine magnetic field, isomery shift and volume fractions of phases were determined by Mossbauer spectroscopy. It is also found that volume fraction of thermally induced martensite and M(S) temperature decreased with the increasing Mo content. (c) 2006 Elsevier B.V. All rights reserved
