MetalsThe superelasticity of CuZr shape memory alloys (SMAs) originates from stress-induced transformations between the B2 (austenite) and B19’ (martensite) phases. Grain size is a key parameter affecting the superelasticity of shape memory alloys.

Surface Characterization of NiTi Superelastic and Shape Memory Alloys After Electrolytic Polishing [PDF]
Materials Research, 2017 For the biomedical application of NiTi alloys, an excellent surface finishing process is required to guarantee high corrosion resistance and biocompatibility, eliminating the allergenic and toxic effects associated with the release of nickel ions in the ...

Superelastic Softening of Ferroelastic Multidomain Crystals [PDF]
Ferroelectrics, 2012 Many proper and improper ferroelastic materials display (at sufficiently low measurement frequencies) a huge elastic softening below Tc. This giant elastic softening, which can be suppressed with uniaxial stress, is caused by domain wall motion. Here we shortly review our results on frequency and temperature dependent elastic measurements of some ...

Stress-Induced Phase Transformations in Shape-Memory Polycrystals [PDF]
, 2008 Shape-memory alloys undergo a solid-to-solid phase transformation involving a change of crystal structure. We examine model problems in the scalar setting motivated by the situation when this transformation is induced by the application of stress in a ...

Superelastic and pH-Responsive Degradable Dendrimer Cryogels Prepared by Cryo-aza-Michael Addition Reaction [PDF]
, 2018 Dendrimers exhibit super atomistic features by virtue of their well-defined discrete quantized nanoscale structures. Here, we show that hyperbranched amine-terminated polyamidoamine (PAMAM) dendrimer G4.0 reacts with linear polyethylene glycol (PEG ...

Active superelasticity in three-dimensional epithelia of controlled shape [PDF]
, 2018 Fundamental biological processes are carried out by curved epithelial sheets that enclose a pressurized lumen. How these sheets develop and withstand three-dimensional deformations has remained unclear.
