This article presents our take on the area of bulk ultrafine-grained materials produced by
severe plastic deformation (SPD). Over the last decades, research activities in this area have …

The phase transformation mechanisms of NiTi shape memory alloy (SMA) during
electromagnetic pulse welding (EMPW) of Al/NiTi dissimilar alloy joints were studied. Two …

Molecular dynamics simulations are performed to investigate temperature-and stress-
induced phase transformations in nanocrystalline nickel-titanium shape-memory alloys. Our …

Shear-induced amorphization is a phenomenon observed in polycrystalline NiTi shape
memory alloys under severe plastic deformation, but the underlying mechanism of such a …

In situ X-ray diffraction during loading and unloading is used to investigate the effects of
grain size (GS) on the stress-induced nanoscale phase transition (PT) mechanism in …

We investigated the effects of grain size on the rate-dependent thermomechanical
responses of polycrystalline superelastic NiTi (with an average grain size from 10 to 90 nm) …

We fabricate three polycrystalline superelastic NiTi samples with average grain sizes of 110,
60, 35 nm and one crystalline-amorphous NiTi nanocomposite sample to investigate their …

In this review, we systematically reviewed the recent advances in the development of
ultrafine shape memory alloys with unique shape memory effects and superelastic behavior …

Martensitic transformation (MT), strain glass transition (SGT) and the corresponding stress-
strain responses in cold-rolled Ti 49.2 Ni 50.8 shape memory alloys (SMAs) at various …

We have investigated the physical origin of anomalous in-plane thermal expansion (TE)
anisotropy leading to invar-like behavior and negative TE in nanostructured NiTi sheets …
