Abstract The influence of quenching temperature on the shape memory effect (SME) of theFe-Mn-Si polycrystalline alloys and their martensitic transformation temperature have beenstudied. The SME of the hot rolled alloy specimen may be remarkably raised by selected quench-ing temperature, namely, 600--800℃. It is influenced not only by the distribution of ε-phasemorphology but also by its pre-existence.
