Abstrakt: The use of atomic force microscopy (AFM) in the magnetic force mode (MFM) for the determination of austenite (nonmagnetic phase) in duplex and TRIP (transformation-induced plasticity) steels is described. The influence of the sample preparation for the MFM measurements is investigated, showing that a final electropolishing stage is necessary in the case of TRIP-steels.
