Anomalous Electrical Conductivity and Magnetization in Fe–Cr–Ni Austenite–Martensite Alloys

We have measured the temperature dependence of the resistivity and magnetization of a special steel of the Fe–Cr–Ni austenite–martensite class in a wide temperature range (77–1100 K). It is found that at temperatures 77–170 K, the resistivity of the material almost remains unchanged, but upon a furt...

Description
Summary:We have measured the temperature dependence of the resistivity and magnetization of a special steel of the Fe–Cr–Ni austenite–martensite class in a wide temperature range (77–1100 K). It is found that at temperatures 77–170 K, the resistivity of the material almost remains unchanged, but upon a further increase in temperature, the resistivity sharply increases, which is probably a result of disordering. In addition, anomalous behavior of resistivity with vanishing spontaneous magnetization is observed at 910 K, which is associated with the ferromagnet–paramagnet phase transition. Comparison of the measured ρ( T ) dependence with the analogous dependence for 12Kh18N10T austenite stainless steel has not revealed features typical of Fe–Cr–Ni steel.
