In this work, a nominally new Fe‐Mn‐Si based shape memory alloy with a small amount of VC was designed. After an optimized thermo‐mechanical treatment, a shape recovery of more than 90% after an elongation of 4% could be achieved when the alloys were heated up to 225°C. In addition, high recovery stresses of up to 380 MPa could be obtained after heating to 225°C, whereas 330 MPa were obtained after heating to 160°C.
