Identification of the low content of ferrite and martensite in austenitic chromium-nickel steels

G.V. Snezhnoi

The results of the initial stage  and  transitions at small plastic deformation and heat treatment of steels 18-10 shows. The temperature dependence of magnetic susceptibility  of a separation of phases -martensite and -ferrite obtained. Magnetometer method for quantitative determination and separation of small amounts of -ferrite and -martensite strain present simultaneously in the austenitic matrix proposed. The temperature hysteresis curves of , caused a phase transformation, and changes the magnetic state of the deformed austenite were found.

Key words: austenitic chrome-nickel steel, ferrite, martensite deformation, magnetic susceptibility.
