Superelastic Effect in Polycrystalline Ferrous Alloys
Journal Science – Superelastic Effect in Polycrystalline Ferrous Alloys In superelastic alloys, large deformation can revert to a memorized shape after removing the stress. However, the stress increases with increasing temperature, which limits the practical use over a wide temperature range. Polycrystalline Fe-Mn-Al-Ni shape memory alloys show a small temperature dependence of the superelastic stress …
