Fretting wear is the main factor restricting application of titanium alloy as compressor blades. Preparing a kind high entropy (HEA) coating an effective way to improve fretting resistance under temperature conditions. Thus, in present work, FeCrAlMoxNby HEA was fabricated on Ti-64 substrate by laser cladding technology. The phase composition, microstructure and at temperatures (200 °C, 300 °C 400 °C) were investigated. It demonstrated that coatings exhibited dense uniform microstructures...
In this article, two-scale 3D finite element (FE) models, the microscopic repeated unit cell (RUC) model for yarn, and mesoscopic-repeated woven composite, are presented to predict effective stiffness properties of orthogonal interlock composites. The micro-RUC yarn is based on a hexagonal array fibers. Undulation yarns in novel 3-D meso-RUC composite described by Hermit-spline function. periodic boundary conditions applied models during FE analysis order ensure that both displacement stress...
This paper presents a functional nanoparticle-enhanced enzyme-linked immunosorbent assay (FNP-ELISA) for detection of enterohemorrhagic Escherichia coli (EHEC) O157:H7. Immunomagnetic nanoparticles (IMMPs) conjugated with monoclonal anti-O157:H7 antibody were used to capture E. Beacon gold (B-GNPs) coated polyclonal and biotin single-stranded DNA (B-DNA) then subjective immunoreaction O157:H7, which was followed by streptavidin-horseradish peroxidase (Strep-HRP) B-GNPs based on biotin-avidin...
In this paper, a new piezo-actuated XY parallel compliant mechanism for large workspace nano-positioning with decoupled motions is developed by incorporating novel Z-shaped flexure hinge (ZFH)-based into the mirror-symmetrically distributed structure. The bridge-type and two-stage leverage mechanisms serve as preliminary displacement amplifiers, while further amplification motion transfer output are achieved means of ZFH mechanism. Based on finite element theory, high-precision analytical...
Facing the current lack of clarity in temperature selection mechanisms for warm rolling medium Mn steel, three methods were conducted 3Mn steel according to temperatures dual-phases region or ferrite region. Subsequently, effect heat treatment on austenite morphologies and tensile properties warm-rolling samples was studied. Rolling dual-phase regions (750 °C) led heterogeneous morphology composed equiaxed lamellar grains while (600 resulted significant cementite precipitation absence...
In this work, a generalized expression of the photoacoustic (PA) effect in multilayer material is derived. This takes thermal and optical properties geometry structure, as well contact resistances between layers into consideration. addition, composite piston model consisting mechanical PA developed interpreted from viewpoint thermodynamics. Mistakes occurring before are pointed out corrected. It also shown that has an isochoric character for polytropic with factor (2−1/γ) piston. The theory...
In this paper a new version of Differential Quadrature Method (DQM) is proposed and then extended to analyse frame structures. The method, called the Element (DQEM), retains all advantages earlier differential quadrature method overcomes some critical shortcomings existing in original DQM. is, however, different from (QEM) by Striz et al. methodology explained details herein via beam element numerical examples are given show efficiency present method. © 1997 John Wiley & Sons, Ltd.
Nonlinear free vibration of graphene platelets (GPLs) reinforced dielectric composite beam subjected to electrical field is analysed. Effective medium theory adopted approximate the overall Young's modulus and permittivity GPLs composite. The Poisson's ratio mass density composites are estimated by rule mixture. Based on Timoshenko theory, governing equations for established using Hamilton's principle nonlinear von Kármán strain–displacement relationship. Numerical solution obtained through...
The photoacoustic (PA) technique is one of many techniques for measuring thermal conductivity thin films. Compared with other measurement, the method relatively simple, yet able to provide accurate data types films and bulk materials. In this work, PA measurement in a high frequency range made possible by newly developed apparatus, which extends limit technique. Thermal conductivities SiO2 thicknesses from 0.05 0.5 μm on Si wafer, e-beam evaporated nickel film barrier coatings are obtained....
