Shape Memory and Huge Superelasticity in Ni–Mn–Ga Glass-Coated Fibers
Ni–Mn–Ga polycrystalline alloy fibers with diameters of 33 μm are reported to exhibit significantly improved ductility and huge superelastic and shape memory strains in comparison to conventional brittle bulk polycrystalline alloys. Particularly, the recoverable strain of the Ni54.9–Mn23.5–Ga21.6 fiber can be as high as 10% at 40 ◦C. Such optimized behavior has been achieved by a suitable fabri...
متن کاملShape memory effect and superelasticity in a strain glass alloy.
The shape memory effect and superelasticity are usually found in alloys exhibiting spontaneous martensitic transformation. Thus it is hard to imagine that such interesting effects can appear in a system without a martensitic transformation. In this Letter we show shape memory and the superelasticity effect in a nonmartensitic Ti48.5Ni51.5 alloy, which has no martensitic transformation but under...
متن کاملShape memory and superelasticity in polycrystalline Cu–Al–Ni microwires
We report a strategy to significantly improve the ductility and achieve large superelastic and shape memory strains in polycrystalline Cu–Al–Ni shape memory alloys that are normally brittle. We use a liquid-phase Taylor wire forming process to obtain microwires of 10–150 m diameter with a bamboo grain structure. The reduction of grain boundary area, removal of triple junctions, and introduction...

Title of Document: MAGNETOELASTIC COUPLING IN NiMnGa FERROMAGNETIC SHAPE MEMORY ALLOY Peng Zhao, Doctor of Philosophy, 2006 Directed By: Professor, Manfred Wuttig, Department of Materials Science and Engineering NiMnGa alloys have attracted extensive attention because their ferromagnetic characteristic provides an additional degree of freedom to control both the shape memory effect and the mult...
متن کاملDirect observation of hierarchical nucleation of martensite and size-dependent superelasticity in shape memory alloys.
Martensitic transformation usually creates hierarchical internal structures beyond mere change of the atomic crystal structure. Multi-stage nucleation is thus required, where nucleation (level-1) of the underlying atomic crystal lattice does not have to be immediately followed by the nucleation of higher-order superstructures (level-2 and above), such as polysynthetic laths. Using in situ trans...
