In this study, the shape, size and distribution of precipitates and/or clusters according to the alloy composition (Mg: 0.4 ~ 0.8 w.t. %, Si: 0.6 ~ 1.2 w.t. %) of Al-Mg-Si based alloy sheets were simulated by Monte Carlo method in the condition of batch-type heat treatment process. Based on the results, the precipitates and clusters in the suggested cooling with and without pre-aging conditions (Solid-solution condition: 400 ~ 500 ºC, cooling condition: ~150 ºC, pre-aging condition: 80 ~ 120 ºC) were predicted by Matcalc software (computer simulation of phase transformation and microstructure evolution in metallic systems). The optimized heat treatment conditions derived based on the analysis results were applied to the small-sized coils, and the microstructure and mechanical properties were evaluated respectively. Most cluster sizes were less than 5nm observed in HrTEM. The yield stress and elongation to failure were above 100 MPa and 25 %, respectively. In addition, the Al-Mg-Si based sheets containing the scraps of combinations of 3xxx, 5xxx and 6xxx series sheets were heat treated in the same condition, and microstructure and mechanical properties of the heat-treated recycled sheets were evaluated. © 2023 28th IFHTSE 2023 Congress.

Predicting State of Health (SoH) of Second Life Batteries (SLB) is a challenging aspect when the repurposer is often surrounded by uncertainty in historical data from Electric Vehicle (EV). The EV Original Equipment Manufacturer (OEM) hardly reveal any battery related data to public domain, it also reciprocates to the repurposer. However, SoH estimation demands minimal historic data to compare past and present state of the batteries. Thus, when repurposer examines SoH of SLB, it is mandated to adhere on either of reference Performance Test (rPT) or the one which is recommended in the cell datasheet by the cell manufacturer to compare the SLB performance with the past data. While executing this process, the repurposer often conducts multiple charge and discharge cycles to comment on SoH of the SLB cells. Hence, in order to reduce the processing time in conducting cycling experiments, and to predict the SoH of SLB, the authors proposed a novel approach on regenerating voltage and capacity profile through Constant Voltage Sampling (CVS) process considering SLB perspective. The regenerated curve is deemed as synthetic curve wherein the forward and backward prediction of SoH is carried out. raw test data is accessed from University of Michigan repository for serving as reference to the authors. The results of voltage and capacity profile are validated successfully for SoH ranges from 100% to 80%. With the help of CVS technique, discharge voltage and capacity profiles for SoH ranges from 80% to 50% were reconstructed successfully to define the health indicators governing SoH and remaining useful Life (ruL). © 2024 IEEE.

Thermoelectric energy conversions have been attracting much attention, which directly generate electric energy from thermal one by utilizing the Seebeck effect. Among various efforts to improve the conversion efficiency, control of phonon propagation with nano-scale structures has been popular, which utilize phonon scatterings on structural interfaces. The concept is based on the difference of mean free path (MFP) between phonons and electrons (charge carriers). In typical cases with silicon-base devices, MFP of phonons is in an order of 100 nm while that of electrons is 1-10 nm. Thus structures of 10-100 nm size are expected to be effective for suppressing the phonon heat transfer without much reducing the electric transport, leading to conversion efficiency improvement. We have developed a numerical scheme to investigate phonon transport based on the Boltzmann transport equation (BTE) for time development of the phonon distribution function. To treat various shapes of nano-scale structures, we have newly introduced a VOF (volume of fluid) like scheme. In the presentation, we will show results of several test systems of nano-structured Si thin films, with evaluation of effective electric conductivity, to discuss how much nano-scale structures improve the conversion efficiency. © Published under licence by IOP Publishing Ltd.

We report a method for controlling the viewing angle using twisted nematic liquid crystal (TN-LC) materials for automotive display applications. We achieved switching between normal and privacy modes with the change in viewing-angle-dependent retardation through the reorientation of the TN-LC molecules under crossed polarizers by applying a vertical electric field.

We propose a waveguide absorber (WGA) based on a spiral acoustic black hole (ABH) to reduce vibration in plates. The geometrical dimensions of the WGA are determined so that it has a lower cut-on frequency than a target frequency by using the impedance method. We also determine the attachment location and direction of the WGA on a plate to maximize its damping performance based on the structural intensity analysis. A couple of WGAs attached to a plate could reduce the mobility of the plate by more than 10 dB. In addition, the WGAs had far less weight but could achieve larger peak reductions compared to thick damping material or spiral ABHs attached to edges. © ICA *** rights reserved

To understand the sealing characteristics of temporary plugging agents (TPA) in the borehole, a system was established for simulating high pressure temporary plugging experiments. The influence of the type and the concentration of TPA, the carrying liquid viscosity and the pump displacement on the sealing characteristics are studied, and the comparison and selection experiments of TPA are also performed. It can be concluded from experimental results that i) the higher viscosity of carrying liquid leads more TPA to going into the low-angle-borehole, resulting in better sealing characteristic;ii) the larger pump displacement causes more boreholes blocked by the TPA (especially the number of blocked low-angle-boreholes are more than that of blocked high-angle-boreholes);iii) both low-angle-borehole and high-angle-borehole are filled with more TPA duo to the higher concentration of TPA;iv) the sealing efficiency of TPA-knot is the highest, followed by TPA-particle and TPA-ball, and the TPA-fiber is the lowest. For obtaining the excellent sealing efficiency, it is recommended the mixed use of TPA-knot, TPA-particle and TPA-ball. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.

Micromilling is a subtractive manufacturing process that presents challenges due to scale effects and rapid tool wear. To understand the evolution of surface quality when increasing the machined length during the micromilling process, this study assessed the surface roughness, topography, and defects of slots micromilled on Ti-6Al-4V. For the experiments, 1 mm diameter flat end mills were employed, and the cutting parameters were varied using a full factorial design. Subsequently, the surface texture field parameter Sa was assessed every 20 mm, up until the machining length of 260 mm. The analysed results led to the conclusion that, for the adopted set of parameters and the machining length of up to 260 mm, surface roughness was not significantly correlated to the machined length in the micromilling process of Ti-6Al-4V, as the Pearson coefficient, obtained from the correlation analysis, was -0.052. However, the surface roughness was mainly influenced by feed rate (Pearson coefficient of 0.82), with higher feed rates leading to roug surfaces (up to Sa = 0.4 μm) duhere to the tool load increase that causes wider feed marks on the surface. regarding the feed marks, they were affected by the tool rotational frequency due to system vibration. Additionally, surface defects of adhered material, smearing, tearing and side flow were observed. For lower feeds, material adhesion was the main type of defect observed, while higher feed rates favoured the side flow phenomenon. © 2024 The Authors. Published by Elsevier B.V.

Large agglomerates are dielectric defects in nanocomposites, which are polymer matrix added nanoparticles. However, a method for quantifying the critical agglomerate size to improve the dielectric breakdown strength of nanocomposites has not yet been established. In this study, the dependence of the AC breakdown strength on the agglomerate size of epoxy/TiO2 NC is estimated using an electron avalanche breakdown model. © 2022 IEEE.
