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 c...

Abstract An Fe–10Cr–4Al alloy containing reactive elements developed for application in high-temperature liquid lead environments was analyzed after exposure 600 and 750°C with dissolved oxygen 1,000–2,000 h. Atom probe tomography, transmission electron microscopy, X-ray scattering were all used to study the protective oxide formed on surface. Exposure at resulted a 2-μm thick oxide, whereas 60...

Alloys Fe-(0, 5, 10)Cr-10Al (all in at.%) were oxidized at 900 o C in 1 atm oxygen to study the effect of Cr additions on the oxidation behavior. The oxidation kinetics was recorded with a thermal microbalance. The morphologies and microstructures of the oxide scales were examined using SEM, EDS, and XRD. Fe-10Al developed an Al2O3-rich scale during the initial stage of oxidation, and a non-pro...

This study systematically investigated the effects of heat and thermomechanical treatments on pseudo-elastic behavior an Fe-based shape-memory alloy (Fe–17Mn–5Si–10Cr–4Ni-1(V, C) %wt.). First, samples were solution-annealed at 1000 °C for 2 h aged 760 6 h. A treatment was then applied to heat-treated samples. The microstructure mechanical properties (i.e., 0.1% yield stress pseudo-elasticity) c...
