Journal ArticleDOI
Magnetic and martensitic transformations of NiMnX(X=In,Sn,Sb) ferromagnetic shape memory alloys
Yuji Sutou,Y. Imano,N. Koeda,Toshihiro Omori,Ryosuke Kainuma,Kiyohito Ishida,Katsunari Oikawa +6 more
TL;DR: Martensitic and magnetic transformations of the Heusler Ni50Mn50−yXy (X=In, Sn and Sb) alloys were investigated by differential scanning calorimetry measurement and the vibrating sample magnetometry technique.
Journal ArticleDOI
Cobalt-base high-temperature alloys
TL;DR: Cobalt-base superalloys showing a high-temperature strength greater than those of conventional nickel-basesuperalloys are identified and structures offering great promise as candidates for next-generation high-Temperature materials are identified.
Journal ArticleDOI
Ferrous Polycrystalline Shape-Memory Alloy Showing Huge Superelasticity
TL;DR: A ferrous polycrystalline, high-strength, shape-memory alloy exhibiting a superelastic strain of more than 13%, with a tensile strength above 1 gigapascal, which is almost twice the maximum supeRELastic strain obtained in the Ni-Ti alloys.
Journal ArticleDOI
Superelastic effect in polycrystalline ferrous alloys.
Toshihiro Omori,Keisuke Ando,M. Okano,Xiao Xu,Yuuki Tanaka,I. Ohnuma,Ryosuke Kainuma,Kiyohito Ishida +7 more
TL;DR: Polycrystalline Fe-Mn-Al-Ni shape memory alloys show a small temperature dependence of the superelastic stress because of a small transformation entropy change brought about by a magnetic contribution to the Gibbs energies.
Journal ArticleDOI
Effect of grain size and texture on pseudoelasticity in Cu–Al–Mn-based shape memory wire
TL;DR: In this article, the effect of grain size on pseudoelastic behaviors was investigated in shape memory alloy (SMA) wires, and the Taylor and inverse Schmid factors were expressed using the volume fraction of three-dimensional constrained grains.
