The high entropy alloy concept offers unique opportunities for the design of advanced materials with unprecedented properties. However, hitherto most research efforts are focused on structural materials. Here, by employing core effect severe lattice distortion in alloys, a novel functional NiCuTiHf0.6Zr0.4 exhibiting intriguing wide-temperature-range perfect superelasticity broad temperature range from 263 to 463 K and giant elastocaloric maximum adiabatic change 9.3 is developed. This work...
High-temperature shape memory alloys (HTSMAs) show enormous potential for applications as energy conversion devices, actuators and sensors in automotive, aerospace, exploration industries, but they suffer from strength decrease microstructural instability at elevated temperatures, rendering it difficult to achieve satisfactory high-temperature superelasticity. Here, a novel Ti20Hf15Zr15Cu25Ni25 high-entropy HTSMA exhibiting large superelasticity with fully recoverable strain of 4.0%...
The rapid development of aerospace, automotive, and energy exploration industries urgently requires high-temperature shape memory alloys (HTSMAs) which are utilized as compact solid-state actuators, sensors, conversion devices at elevated temperatures. However, the currently prevailing Ni–Ti–X (X = Pd, Pt, Hf) HTSMAs very expensive owing to high cost Hf elements, greatly limits their widespread applications. Here, we have developed an inexpensive (Ni50Mn35.5Ti14.5)99.8B0.2 bulk...
Meta-magnetic shape-memory alloys combine ferroelastic order with ferromagnetic and exhibit attractive multifunctional properties, but they are extremely brittle, showing hardly any tensile deformability, which impedes their practical application. Here, for the first time, an Ni–Cu–Co–Mn–In microwire has been developed that simultaneously exhibits a magnetic field-induced first-order meta-magnetic phase transition huge superelasticity. A temperature-dependent in situ synchrotron high-energy...
Using ab initio alloy theory, we investigate the equilibrium bulk properties and elastic mechanics of single bcc solid-solution AlxHf1−xNbTaTiZr (x = 0–0.7, 1.0) high entropy alloys. Ab predicted volume is consistent with available experiment. We make a detailed investigation alloying effect Al Hf on volume, constants polycrystalline moduli. Results imply that partial replacement increases stability phase decreases ductility HEAs. The inner Al0.4Hf0.6NbTaTiZr by calculations ideal tensile strength.
Metamagnetic shape memory alloys exhibit a series of intriguing multifunctional properties and have great potential for applications in magnetic actuation, sensing refrigeration. However, the poor mechanical these with hardly any tensile deformability seriously limit their practical application. In present work, we developed Ni-Fe-Mn-In microwire that exhibits both giant, superelasticity magnetic-field-induced first-order phase transformation. The recoverable strain is more than 20%...
The present study aimed to investigate the role of miRNAs during pathogenesis oral lichen planus (OLP). OLP is a chronic inflammatory disorder, which involves T‑cell mediated autoimmunity and affects skin, scalp, nails mucosa. Abundant T lymphocytes have been demonstrated infiltrate mucosa, in activated cells trigger apoptosis epithelial cells. Overexpression osteopontin (OPN) CD44 has observed mucosa patients with OLP, it confirmed that OPN suppresses CD8+ via CD44. initially detected...
Reversibility of phase transformation, a basic requirement for functional properties shape memory alloys, such as superelasticity, is severely affected by plastic deformation. Here, strain glass has been utilized to improve the reversibility transformation. The incorporation Al into Ti-Zr-Ni-Cu induces and endows alloy with reversible transformation thus ideal superelasticity. In situ x-ray diffraction dynamic mechanical experiments were verify mechanism conversion from plasticity This work...
Based on the Bailey-Norton elastic-plastic constitutive model to asphalt mixture, Mohr-Coulomb plastic unbounded granular material, and ABAQUS finite element platform, resistance ability rutting of 4 typical pavements are studied. Results reveal that: existence material between layer cement treated appears negative effect ability; factors such as temperature, tire-road contact pressure, traffic volume, modulus thickness layers have significant effects pavement resistance; prediction models...
Refractory cough, a chronic cough with an unclear diagnosis or poor treatment response. The symptoms are often stubborn and persistent, causing serious complications lowering the patient's quality of life. Cough hypersensitivity syndrome (CHS) is proposed as potential cause, reducing sensory nerve hyperresponsiveness suggested effective treatment. However, current drugs have low efficacy benefit rates numerous side effects. This trail proposes using duloxetine, selective 5-HT norepinephrine...
Abstract A compelling demand exists for high-performance high-temperature shape memory alloys (HTSMAs) that can be applied as intelligent components in the rapidly developing aerospace, robotics, manufacturing, and energy exploration industries. However, existing HTSMAs are handicapped by their high cost unsatisfactory functional properties, which impede practical application. Here, using strategy of creating an oligocrystalline structure, we have developed a high-performance, cost-effective...
