Ultrasonic testing methods exhibit great potential for nondestructive evaluation in various industrial materials including composite materials. However, the wave-propagation behavior becomes complicated due to combined effects of anisotropy and dispersion, which brings challenges defect detection anisotropic media. In this work, method imaging defects is proposed by combining phase-shift migration (PSM) coordinate transformation. As a demonstration, Lamb wave propagation highly plates...
Abstract Photoacoustic transducers with a single photoacoustic conversion layer generate waves relatively uniform energy distribution across wide bandwidth. The spectral characteristics of the formed by multilayer optical absorbers are studied. Under excitation, transduce laser pulse into train ultrasound pulses varying time intervals. time-domain and generated acoustic field analyzed in simulation based on boundary conditions, number layers, spacing absorber. results indicate that, constant...
A new silicon-based adsorbent with good adsorption performance on Pd(II) was synthesized from mesoporous silica as a carrier and 1,4,7,10-tetraazacyclododecane functional ligand. The batch method used to investigate evaluate the of in HCl-HNO3 solution. Influencing factors such contact time, pH, temperature, initial concentration, elution conditions were systematically investigated optimized. Simultaneously, kinetics, thermodynamics, isotherms investigated. results revealed that under...
A three-dimensional finite element model was employed to simulate the cladding process of Ni-Cr-B-Si coatings on 16MnR steel under different parameters laser power, scanning speed, and spot diameter. The temperature residual stress distribution, depth heat affected zone (HAZ), optimized for remanufacturing technology were obtained. orthogonal experiment intuitive analysis HAZ performed study influence parameters. new criterion based ratio maximum tensile fracture strength substrate proposed...
Abstract Minimizing the residual stress and deformation of manufactured product consequent to selective laser melting (SLM) process is always a primary focus in realm additive manufacturing. This paper studied influence different scanning strategies on thermal-mecha nical characteristics SLM Ti6Al4V. Numerical simulation experimental tests were employed concerning three process: Z-shaped, outer spiral, inner spiral. Allowing for latent heat phase change, thermal radiation, convection effect,...
To account for the microstructure evolution corresponding to changed scanning speed, thermal-fluid dynamic model of meltpool during selective laser melting (SLM) process Ti6Al4V was established by numerical method study thermal characteristics and melt flow behavior. Results showed that increasing speed would result in a lower peak temperature but higher heating cooling rate on specimen. Both size its duration were reduced with increased velocity. Typically, waved solid/liquid interface...
After washing, milling and calcining, the graphite rods recycled from waste dry batteries were used as raw material to prepare expandable by chemical oxidation (using acetic anhydride inserting potassium dichromate oxidant), expanded was prepared obtained microwave radiation (MW) at 1000W for 60s.The characterization of infrared spectroscopy (IR) scanning electron microscopy (SEM) have been discussed. The results show that it is feasible using batteries.
