The mechanical characteristics of magnesium-based composites made by stir casting are examined in this work. Because of their versatility and low weight, magnesium alloys have attracted attention. In order to improve the mechanical properties of a molten magnesium alloy, reinforcing elements are added during the stir casting process. Magnesium was chosen as the basic alloy for the experiment because of its excellent strength-to-weight ratio and low density. Particles of aluminum oxide (Al2O3) and silicon carbide (SiC) were introduced as reinforcements in different concentrations. Stirring was done after the mixture was melted in a regulated setting to guarantee that the reinforcing agents were distributed evenly. Following solidification, specimens were ready for examination. The composite materials have significantly improved, according to the mechanical testing. The tensile strength and hardness of the composites exhibited significant improvement with an increase in reinforcing content. Composites treated with SiC showed excellent tensile characteristics and a notable improvement in strength. Conversely, Al2O3-reinforced composites showed increased hardness values, which may make them appropriate for applications requiring resistance to wear. The study emphasizes how well the stir casting process works to create composites based on magnesium that have improved mechanical qualities.

An extensive investigation is conducted on Mg-based composites reinforced with various sorts of particles, which are manufactured by stir casting. The materials under examination include AZ31, AZX915, and AZ91 alloys, which have been strengthened with fly ash, TiC, Gr, (B4C), and carbon nanotubes. The wear behavior, mechanical characteristics, and microstructural properties of these composites are analyzed under different loads and circumstances. The findings indicate that the choice and concentration of strengthening significantly impact WRs, COF, and mechanical strength. Multiple wear mechanisms, including as abrasion, tribo-oxidation, and delamination, are acknowledged. The investigation is currently focused on the application of advanced techniques, including as vacuum SCTand ultrasonic-assisted solidification processing, to enhance the characteristics of materials. In addition, research investigates the synergistic benefits of different strengthenings, such as the combination of hard particles (TiC, B4C) and soft particles (Gr), to enhance WR. It emphasizes the significance of tribological elements, such as load, velocity, and SD. Decision trees have demonstrated effectiveness in predictive modeling when employed in machine learning models. The study contributes valuable insights to the progress of MMC that exhibit enhanced mechanical and tribological properties. The automotive and aerospace engineering sectors may find use for these composites.

Concerns regarding cybersecurity, safety, privacy, and public acceptance are raised by the integration of autonomous vehicles (AVs) into sophisticated transportation networks. The purpose of this study is to investigate and evaluate the various perspectives that surround AVs. Evaluating public acceptability entails determining degrees of confidence and concerns about AV technology. The ability of AVs to handle challenging traffic situations while maintaining pedestrian and passenger safety is a safety concern. Concerns about privacy mostly concern how personal information is gathered, used, and safeguarded in AV systems. Implications for cybersecurity also highlight how susceptible antivirus software is to possible hackers or system breaches. This research contributes to a thorough knowledge of the potential and problems associated with the broad adoption of autonomous cars within futuristic transportation ecosystems by looking at these factors.
