In
this study, the microstructure and magnetic properties of martensite
transformation induced were investigated in Fe based alloys (Fe-15,83%Mn-2,18%V
ve Fe-18,50%Mn-2,27%Cu alloys). Micro structures were studied with Scanning
Electron Microscope. The effect of the
adding V and Cu in Fe-Mn alloy on the magnetic properties has been investigated
by Mössbauer spectroscopy technique respectively. It was investigated that the
adding of V and Cu  to Fe-Mn alloy
reveals the ferromagnetic and paramagnetic properties of alloy respectively. The
other result of this study is the rate of Mn amount in Fe-Mn-X alloy. If the Mn
rate in the Fe-Mn-X alloy is 18% or more, no α-martensitic transformation have
been observed. Thus, this study showed that the additional atom has great
importance on changing the magnetic properties of alloys.
