Direct aluminium–stainless steel joints are difficult to create by the vaporized foil actuator welding (VFAW) method because brittle intermetallic compounds (IMCs) tend form along interface. The use of an interlayer as a transition layer between two materials with vast difference in hardness and ductility was proposed solution reduce formation IMCs. In this work, VFAW used successfully weld sheet aluminium alloy 5A06 stainless 321 3003 interlayer. Input energy levels 6 kJ, 8 10 12 kJ were...
Abstract In order to improve the comprehensive mechanical properties of welded joints 5A06 aluminum alloy, friction stir (FSW) were subjected deep cryogenic treatment (DCT). The microstructure and characterised using metallographic microscopy, x-ray diffractometer (XRD), energy spectrometer, microhardness tests, tensile tests. experimental results show that DCT refines structure significantly due large temperature difference. This refinement from an increase in Mg atoms within α -Al solid...
Abstract The composite structure of aluminium alloy and stainless steel provides a wide range comprehensive advantages, encompassing properties such as lightweight, high strength, corrosion resistance. These advantages make particularly suitable for various applications in industries transportation chemicals. One innovative solid-phase welding technology that is well suited joining dissimilar materials vaporizing foil actuator welding. This allows the structures made steel, despite...
Conventional welding methods encounter significant challenges, including poor weldability, low joint strength, and the formation of brittle intermetallic compounds, primarily due to substantial disparities in physical chemical properties aluminum iron. To mitigate these issues, vaporizing foil actuator (VFAW) process has emerged as a highly promising solid-phase technology, particularly suitable for joining dissimilar metals with pronounced differences properties, such alloys stainless...
Abstract In this study, the application of magnetic pulse welding was employed for production tubular joints using 1060 aluminium and 321 stainless steel. Two crucial process parameters, charging voltage, gap between outer inner tubes, were subjected to mechanical property tests morphology analysis. The that exhibited favourable properties obtained with a size 1.25 mm voltage exceeding 3.5 kV. presence intermetallic compounds at joint interface indicates occurrence fusion in transition zone....
The purpose of this study was to rapidly improve the denitrification packing activity in pond sludge sewage plants, realize engineering application embedding immobilization, and explore characteristics microbial community packing. effects different C/N ratios, temperature, pH on filler were studied by batch experiments, biological high-throughput sequencing. Results showed that 10, temperature 30℃, 7.5±0.3, resumed 5.37 mg·(g·h)-1 initial after 7 days. Under optimized culture conditions...
