Recent Advancements in Development and Application of an Iron-based Shape Memory Alloy at Empa

The Fe-SMA developed at the Swiss Federal Laboratories for Materials Science and Technology (Empa) has an alloy composition of Fe–17Mn–5Si–10Cr–4Ni–1(V,C) exhibits excellent shape memory effect on heating 160 °C or above. feature equips with a unique self-prestressing ability that can be exploited many civil engineering applications. In addition to ability, high elastic modulus (165 GPa), low cost, machinability compared nickel copper-based SMAs, which makes it more suitable structural current work aims provide overview recent advancements in research development Empa. To this end, related material development, applications Fe-SMAs prestressing reinforced concrete (RC) metallic structures, introduction reinforcements market alongwith some field are presented. paper concludes opportunities challenges associated using infrastructure.
