In this work the authors present the properties of the Fe59Mn27Ni7Cr3Si4 (at. %) shape memory alloy. Two different phases were discovered during the XRD analysis and Fe-Mn phase was identified. The hardness of the investigated material in the as-cast state was 194 HV. The nano hardness was 511 HV and Young modulus was determined as 159 GPa. AFM and LFM tests allowed to observe linear arrangement of one phase formed as multiple irregular separations. Shape memory effect was not observed in the temperature range 22 – 600oC.
