Thermal cycling stability of Ni55Mn25Ga18Ti2 high-temperature shape memory alloy
工程科学学报, 2022 Research on high-temperature shape memory alloys has attracted much attention due to the control requirements of the high-temperature drive (>100 ℃) and the overheating warning in high voltage transmissions, nuclear power, aerospace, automotive, oil ...

Shape invariance through Crum transformation
, 2006 We show in a rigorous way that Crum's result on equal eigenvalue spectrum of Sturm-Liouville problems can be obtained iteratively by successive Darboux transformations. It can be shown that all neighbouring Darboux-transformed potentials of higher order,

Transformation Volume Effects on Shape Memory Alloys
Metals, 2013 It is generally accepted that the martensitic transformations (MTs) in the shape memory alloys (SMAs) are mainly characterized by the shear deformation of the crystal lattice that arises in the course of MT, while a comparatively small volume change ...

Shaping business sector transformations
Ökologisches Wirtschaften - Fachzeitschrift, 2022 The climate crisis requires a transformation towards a climate-neutral economy. This implies considerable pressure for business sectors with a high carbon footprint. The key challenge here is to shape the structural change in a way that is ecologically, economically and socially successful.

High-temperature shape memory properties of Cu15Ni35Ti25Hf12.5Zr12.5 high-entropy alloy
Journal of Materials Research and Technology, 2021 The major challenges hindering the application of high-temperature shape memory alloys are their decreased mechanical strength and thermal stability. Herein, we present high-temperature shape memory properties of the Cu15Ni35Ti25Hf12.5Zr12.5 high-entropy

Shape Memory Properties and Microstructure of New Iron-Based FeNiCoAlTiNb Shape Memory Alloys
Crystals, 2021 The shape memory properties and microstructure of Fe41Ni28Co17Al11.5(Ti+Nb)2.5 (at.%) cold-rolled alloys were studied at the first time using the values reported in constant stress thermal cycling experiments in a three-point bending test.

A rate-independent model for the isothermal quasi-static evolution of shape-memory materials [PDF]
, 2006 This note addresses a three-dimensional model for isothermal stress-induced transformation in shape-memory polycrystalline materials. We treat the problem within the framework of the energetic formulation of rate-independent processes and investigate ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT We sought to identify potential early risk biomarkers for lung disease in children post‐allogeneic HCT. Patients with pulmonary function tests 3 months post‐transplant and plasma samples between days 7 and 14 post‐HCT were included. Six of 27 subjects enrolled had reduced forced expiratory volume 1 (FEV1) z scores.

Gravity-Induced Shape Transformations of Vesicles [PDF]
Europhysics Letters (EPL), 1995 We theoretically study the behavior of vesicles filled with a liquid of higher density than the surrounding medium, a technique frequently used in experiments. In the presence of gravity, these vesicles sink to the bottom of the container, and eventually adhere even on non - attractive substrates.

Journal of Science: Advanced Materials and Devices, 2019 Since shape memory alloy (SMA) wires can hardly ever be reliably employed under compressive loadings, SMA springs are developed as axial actuators with the ability of withstanding both tension and compression.
