This article reviews recent developments in small-scale mechanical property testing with
some emphasis on intermediate (meso) length scales in complex microstructures and …

Cuboidal micropillars of nanocrystalline superelastic NiTi shape memory alloys with an
average grain size of 65 nm were fabricated by focused ion beam and then subjected to …

Shape memory alloy undergoing reversible martensitic transformation is an important class
of metallic functional materials. In the past two decades, the development of shape memory …

Molecular dynamics simulations are performed to provide a detailed understanding of the
functional degradation of nano-scaled NiTi shape memory alloys containing amorphous …

The superelasticity of nanocrystalline NiTi alloys originates from stress-induced martensitic
transformation, which may exhibit strain localization. The resultant structural instability often …

The response of NiTi shape memory alloy (SMA) changes drastically with the loading rate.
This paper presents a three-dimensional thermomechanically coupled constitutive model to …

Nanoscale grain and high dislocation density are the most common microstructures of
nanocrystalline NiTi alloy. Although grain size and dislocation density influence the …

Two transmission electron microscopy (TEM) based methods were applied to reconstruct
martensite variant microstructures in entire grains of plastically deformed nanocrystalline …

The isothermal aging response at 170° C of three extruded Al–Mg–Si alloys that had been
