A material strength depends on its microstructure, which in turn, is controlled by an
engineering process. Strengthening mechanisms like work hardening, precipitate, and grain …

This review examines the recent literature that has focused on uniaxial compression
experiments of single crystals at the micrometer scale. Collectively, the studies discovered …

The work clarifies several key questions in shape memory research that have eluded
previous studies. The findings show that dislocation slip emanates at austenite-martensite …

Abstract The off‐stoichiometric Ni2MnGa Heusler alloy is a magnetic shape‐memory alloy
capable of reversible magnetic‐field‐induced strains (MFIS). These are generated by twin …

[110]-oriented microcrystals of solutionized 50.7 at.% Ni–Ti were prepared by focused ion
beam machining and then tested in compression to investigate the stress-induced B2-to …

Superelasticity is one promising functional property of shape memory alloys. To utilize
superelasticity in application, sufficient fatigue life (ie, for functional fatigue) during the …

In shape memory alloys, the reversible phase transformations between austenite and
martensite give rise to superelasticity and shape memory properties. Here we systematically …

Cellular materials with periodic architectures have been extensively investigated over the
past decade for their potential to provide multifunctional solutions for a variety of …

This study is aimed at demonstrating the fatigue and fracture mechanisms in nanoscale NiTi
shape memory alloy thin films. During functional fatigue, permanent strains are attributed to …

The study is focused to understand the micro-mechanisms that govern the deformation
behavior of a Ni-rich NiTi alloy at the sub-micron scale. This alloy undergoes reversible …
