Summary: This study investigated the influence of different strain release coefficient calibration methods on the measurement results of welding residual stress, finding that high-value WRSs are significantly overestimated when calibrated using the formula method and experiment. Consideration of stress biaxiality revealed specific distribution trends of WRSs on an orthotropic steel deck.

Summary: Residual stresses in a dissimilar AA1050-DP450 steel magnetic pulse weld were investigated using neutron diffraction for the first time. Tensile residual stresses were observed in the Al sheet and compressive residual stresses in the steel sheet, with different distributions at the joint interface. The asymmetrical shape of the rectangular joint line resulted in lower magnitude of residual stresses along the short side of the weld.

Summary: Friction stir welding was used to fabricate dissimilar welds between 5052 aluminum alloy and DP590 dual-phase steel. The interfacial formation, microstructure, and residual stress distribution were investigated experimentally and numerically. The results showed that increasing rotation velocity led to higher welding temperature, cooling rate, and residual stress level. The numerical predictions of residual stresses were in good agreement with the experimental measurements, validating the reasonability of the simulation. This study is important for predicting residual stress fields in similar or dissimilar friction stir welding.

Summary: Accumulative roll bonding is capable of refining the grain size into the nanometer regime and bonding different metallic sheet materials. This study investigates the residual stresses in aluminum/aluminum and aluminum/steel laminated metal composites (LMCs). The results show that the level of residual stress strongly depends on the bonded materials, and compressive residual stresses are induced in all sheets in the near surface area.

Summary: The study examined the influence of titanium alloy and commercially pure titanium as fillers on dissimilar pulsed tungsten inert gas weldments in terms of microstructure, mechanical/nano-mechanical properties, and residual stresses. The addition of filler alloy improved the tensile properties and nano-mechanical response of the weld joint, while an asymmetrical residual stress profile close to the weld centerline was attributed to the low thermal conductivity of Ti-5Al-2.5Sn.

Summary: In this study, both the depth-sensing indentation (DSI) measurements and finite element (FE) simulations were conducted to investigate the residual stress distribution in the Super304H/T92 dissimilar welded joint with Ni-based filler metal. The residual stresses were measured using the DSI technique and compared with XRD results, showing good agreement. Pile-up and sink-in phenomena were observed in the residual indentation morphologies. A thermal-metallurgical-mechanical finite element analysis was also performed to understand the formation causes of the measured residual stress distribution. The research work in this paper can further expand the applications of the DSI technique in the welding residual stress testing field.

Summary: Generally, as-received steel components before welding undergo various manufacturing processes, leading to the presence of initial residual stresses (IRS). The relationship between IRS and welding residual stresses (WRS) is still unclear, particularly in ultra-high strength steels (UHSS). This study aims to investigate the influence of IRS on WRS in ultra-high strength steel S960 using X-ray diffraction (XRD) measurements. The results indicate that IRS in the weld area are completely eliminated and have no impact on WRS due to the metallurgical and mechanical melting effect. In the heated zone outside the weld area, the initial longitudinal residual stress (σLRS) affects WRS significantly only when it is in tension. In the cold area, WRS are a combination of IRS and welding-induced residual stresses (WIRS), with IRS playing the dominant role in general and having minimal impact on WRS in the weld area.

Summary: The welding-induced residual stresses in dissimilar metal butt-welded joints between P92 steel and SUS304 stainless steel were investigated using finite element analyses and experimental measurements. Factors such as solid-state phase transformation, strain hardening, annealing effect, and thermal expansion coefficient differences were found to have significant influence on the formation of longitudinal residual stresses. The butt-welded joint with X-groove was suggested to be superior in reducing high tensile residual stress compared to the joint with single V-groove.

Summary: An overview of different wind turbine designs was presented and evaluated for their potential use in micro-wind production under poor wind quality situations. The Savonius turbine and the Savonius-Darrieus Hybrid turbine were found to be the most suitable designs. Computational Fluid Dynamic simulations were conducted with these turbines at various wind speeds, and the power output, power coefficients, and Tip Speed Ratios were determined. The results showed that the Hybrid turbine generated more power than the Savonius turbine for most wind speeds, except for 3 m/s.

Summary: Swift developments in electronic devices and future transportation/energy production directions have led to the need for new and contemporary devices with higher power capacities, longer cycle lives, and superior energy densities. Supercapacitors are promising devices with excellent power densities and long cycle lives; however, their commercially available counterparts suffer from inferior energy densities due to limitations in surface area and operating potential window. To address this issue, new high-capacity electrode materials and advanced electrolytes, such as ionic liquids, gel polymers, and solid-state electrolytes, have been developed and evaluated. This review provides a detailed discussion on different types of supercapacitors and the synthesis parameters that impact the physiochemical characteristics of carbon-based active materials. Additionally, the synthesis and applications of carbon nanotubes, graphene, and activated carbon are reviewed, followed by conclusions and outlook.

Summary: In this research, the optimal parameters controlling the performance of a ceramic-based microbial fuel cell (CMFC) were determined using fuzzy modelling and an equilibrium optimizer to increase its output power. Three input parameters were considered: membrane thickness, external resistance, and anode area. By creating an accurate fuzzy model and using an equilibrium optimizer, the optimal values of the input parameters were identified, leading to a 5% increase in CMFC output power compared to experimental work and RSM.

Summary: MXene, a 2D titanium carbide, has been extensively investigated and studied for energy storage purposes due to its excellent properties such as hydrophilicity, metallic conductivity, and high surface redox reactivity. However, the restacking of MXene sheets significantly affects its electrochemical performance. To address this, a composite between MXene and FeCu bimetallic MOF was developed, which not only prevented sheet restacking but also improved specific and rate capacity. The FeCu MOF/MXene electrode exhibited a specific capacity of 440 mA h g(-1) and the MXene-FeCuMOF//AC ASC demonstrated high cyclic stability of 89% after 10,000 alternate GCD cycles.
