Development of High-Entropy Shape-Memory Alloys: Structure and Properties
Успехи физики металлов, 2023 Amongst functional materials, shape-memory alloys occupy a special place. Discovered in the beginning of 1960th in XX century, these alloys attracted quite an attention because of the possibility to restore significant deformation amounts at certain ...

Effect of Valence Electron Concentration in High Entropy Shape Memory Alloys/ Review
Eurasian Journal of Science and Engineering, 2021 The shape memory effect is the ability to recover the shape after deformation on heating or stress. High entropy alloys were found by mixing an equiatomic number of complex components; nowadays, a new generation of un equiatomic components are produced ...

Ultra-low-velocity anomaly inside the Pacific Slab near the 410-km discontinuity
Communications Earth & Environment, 2023 The upper boundary of the mantle transition zone, known as the “410-km discontinuity”, is attributed to the phase transformation of the mineral olivine (α) to wadsleyite (β olivine).

Rapid Surface Reconstruction of In<sub>2</sub>S<sub>3</sub> Photoanode via Flame Treatment for Enhanced Photoelectrochemical Performance. [PDF]
Adv MaterA rapid surface reconstruction strategy is proposed to enhance the charge collection efficiency and stability of indium sulfide (In2S3) photoanode via a high‐temperature flame treatment. This method selectively transforms the In2S3 surface into a diffusionless In2O3 and generates bulk sulfur vacancies, resulting in surface‐reconstructed In2S3 (sr‐In2S3)

Thermoelastic properties on Cu-Zn-Al shape memory springs
Materials Research, 2010 This paper present a thermomechanical study of actuators in form of helical springs made from shape memory alloy wires that can work as actuator and/or as sensor. These abilities are due to the martensitic transformation.

Diffusive and Displacive Phase Transformations in Nanocomposites under High Pressure Torsion [PDF]
Archives of Metallurgy and Materials, 2019 The high-pressure torsion (HPT) of Ti-Fe alloys with different iron content has been studied at 7 GPa, 5 anvil rotations and rotation speed of 1 rpm. The alloys have been annealed before HPT in such a way that they contained different amounts of α/α' and

Journal of Materials Research and Technology, 2019 We investigated the effect of Fe content on the β → α phase transformation behavior of Ti-5Al-xFe (x = 1, 2.5, 4) alloys during continuous cooling. The presence of Fe delayed long-range diffusional phase transformation, thus facilitating diffusionless ...
