In this article, Mg-Cu-Y alloys with two dif- ferent Mg/Cu ratios （in at%） were prepared using a water- cooled copper mold. Scanning electron microscopy and X-ray diffraction were applied to analyze the microstructure and phase composition. Moreover, corrosion resistance and wear resistance were studied systematically. The results show that both Mg65Cu25Ylo and Mg60Cu30Ylo alloys could form a composition of crystalline and amorphous phases. Although the microstructure of Mg65Cu25Ylo con- sists of an amorphous phase and ：t-Mg, Mg2Cu, and Cu2Y crystalline phases, the microstructure of Mg60Cu30Ylo alloy mainly consists of the amorphous phase and ：t-Mg, Mg2Cu. With reducing Mg/Cu ratio, the alloys have better corrosion resistance and wear resistance. The mechanism has also been discussed in detail.

An investigation on strain amplitude-dependent internal friction （IF） of an as-cast high damping Mg-7 wt% Ni alloy was carried out. In the range of our tested strain amplitudes, whether the strain amplitude is increasing or decreasing, the strain amplitude-dependent IF curve can be divided into two stages： one is the strain amplitude weakly dependent part and the other is the strain amplitude strongly dependent part. However, after several cyclic vibrations, the IF values measured during the strain amplitude increasing are smaller than those obtained during the strain amplitude decreasing. The phenomenon is also observed at 100 C. Partial dislocations generate a short-range slip under the cyclic stress to be responsible for it.

In this study, the stirred casting with various processing parameters, such as stirring temperature and stirring speeds, was carried out on the Al–Pb monotectic alloys in order to make Pb particles distribute much more uniformly. More importantly, their damping capacities were systematically studied. The results show tha mechanical stirring can not only make Pb in the aluminum matrix uniformly distribute but also dynamically influence the damping capacity of this alloy system. The Al–Pb alloy was prepared under a slow speed at solid–liquid temperature region, wherein high volume fraction of Pb in alloy could be obtained. The high volume fraction of Pb gives high overall damping capacity. The dislocation damping and interface damping theories are mainly dominated to the alloys.

Temperature is one of the vital influential factors for all physiological and mental *** the influence of temperature on the properties of synaptic devices is of great importance for neuromorphic computing and bionic perception. Here, indium-gallium-zinc-oxide(IGZO) based electrical-doublelayer neuromorphic transistors were proposed for the emulation of temperature-dependent synaptic *** influence of temperature on the synaptic plasticity, including excitatory postsynaptic current, pairedpulse facilitation, and dynamic filtering was investigated. Interestingly, temperature induced spiking AND to OR logic switching was demonstrated in an IGZO-based neuromorphic transistor with two in-plane gate electrodes. Our results provided an insight into the temperature-induced synaptic functions and spiking logic switching, which is interesting for neuromorphic systems with biological fidelity.

In this paper, correspondence relations between the solutions of the static bending of functionally graded material (FGM) Reddy-Bickford beams (RBBs) and those of the corresponding homogenous Euler-Bernoulli beams are presented. The effective material properties of the FGM beams are assumed to vary continuously in the thickness direction. Governing equations for the titled problem are formulated via the principle of virtual displacements based on the third-order shear deformation beam theory, in which the higher-order shear force and bending moment are included. General solutions of the displacements and the stress resultants of the FGM RBBs are derived analytically in terms of the deflection of the reference homogenous Euler- Bernoulli beam with the same geometry, loadings and end conditions, which realize a classical and homogenized expression of the bending response of the shear deformable non-homogeneous FGM beams. Particular solutions for the FGM RBBs under specified end constraints and load conditions are given to validate the theory and methodology. The key merit of this work is to be capable of obtaining the high-accuracy solutions of thick FGM beams in terms of the classical beam theory solutions without dealing with the solution of the complicated coupling differential equations with boundary conditions of the problem.

六垛南闸闸下河道自1995年以来淤积较为严重,尤其近年来淤积速度进一步加剧,亟须治理。本文以历年河道断面观测资料为依据,对比清淤工程实施前后的淤积速度,总结分析六垛南闸闸下河道淤积特点;通过原型沙采样并结合现场试验分析,得出闸下河道泥沙组成、泥沙沉降、泥沙起动等特性指标;通过开展现场冲淤试验,对比分析不同方案的冲淤效果,最终得出合适的清淤方案。结果表明,挡潮闸闸下河道泥沙颗粒较细、淤积密实周期约30天,以水力冲淤为主、配合采用机械搅动方式可大幅提高冲淤效率,在日常运行中充分利用上游来水提高日常冲淤频率,可避免泥沙沉降板结,有效减缓河道淤积速度,有利于长期保持河道过流能力。该研究可为类似平原灌渠制定运行维护和清淤减淤技术方案提供参考。
