Special Issue Information

Dear Colleagues,

The aerospace and automotive industries are constantly seeking innovation in advanced materials, new technologies, and manufacturing processes. In recent years, the utilization of advanced materials, such as metal matrix composites, lightweight alloys, and superalloys, has been particularly prominent. The development of these high-strength, high-performance, and lightweight materials can effectively reduce fuel consumption and costs for aerospace systems and automobiles, while also improving the mechanical performance of components and the sustainability of manufacturing.

This Special Issue aims to collect the latest research on advanced materials and processing technologies in aerospace and automotive engineering. The main topics covered in this Special Issue are based on, but not limited to, the following research topics:

  • Lightweight metals, alloys, and metal matrix composites;
  • High-strength materials, such as high-strength steel, and aluminum alloys, used in the design and manufacturing of lightweight components and mechanical structures;
  • Machining and forming of mechanical components, including additive manufacturing;
  • Advanced joining technologies for structural components;
  • Composition–structure–property relationships, such as microstructure evolution and strengthening mechanisms;
  • Design, testing, and modeling of mechanical components/structures;
  • Tool design and manufacturing for the production of lightweight materials and components.

In recent years, high-performance lightweight and multifunctional aluminum foam sandwiches (AFSs) can be successfully applied to spacecraft, automobiles, and high-speed trains. Friction stir welding (FSW) has been proposed as a new method for the preparation of AFS precursors in order to improve the cost-effectiveness and productivity of the preparation of AFS. In this study, the AFS precursors were prepared using the FSW process. The distribution of foaming agents in the AFS precursors and the structure and morphology of AFS were observed using optical microscopy (OM), scanning electron microscopy (SEM), and X-ray energy dispersive spectroscopy (EDS). The effects of the temperature and material flow on the distribution of the foaming agent during the FSW process were analyzed through experimental study and numerical simulation using ANSYS Fluent 19.0 software. The results show that the uniform distribution of the foaming agent in the matrix and excellent densification of AFS precursor can be prepared when the rotation speed is 1500 r/min, the travel speed is 25 mm/min, the tool plunge depth is 0.2 mm, and the tool moves along the retreating side (RS). In addition, the experimental and numerical simulations show that increasing the welding temperature improves the uniformity of foaming agent distribution and the area of AFS precursor prepared by single welding, shortening the thread length inhibits the foaming agent from reaching the upper sandwich plate and moving along the RS leads to a more uniform distribution of the foaming agent. Finally, the AFS with porosity of 74.55%, roundness of 0.97, and average pore diameter of 1.192 mm is prepared. Full article
