Fe‐based shape memory alloys are supposed to be an interesting and cost‐effective alternative to NiTi‐based alloys. In this work, the thermo‐mechanical behavior of a novel Fe–Mn–Si–Cr–Ni–VC shape memory alloy produced using standard air‐casting facilities is characterized as well as in the hot forged and cold rolled state. Besides a certain pseudoelasticity, the alloy shows good shape recovery properties and remarkably high shape memory stresses after heating to temperatures of only 160 °C, making the alloy interesting for commercial applications that make use of the shape memory effect.
