Mar 19, 2010 · Polycrystalline alloys, such as Fe-Mn-Si (2, 3), Fe-Ni-C (), and Fe-Ni-Co-Ti (5–8), have been developed as “ferrous SMAs,” which, because of their better workability and lower cost, aremercially more attractive than the Ni-Ti–based e Fe-Mn-Si–based alloys are now used for pipe couplings and fishplates. One drawback of existing ferrous SMAs is that …
