With the increasingly excellent performance of magnesium alloy materials, magnesium alloys are increasingly widely used under the urgent need for weight reduction in aerospace applications. However, due to the severe aviation environment, the strength, co.rosion resistance and electrical co.ductivity of magnesium alloy materials need to be further improved. Many scholars are co.mitted to studying higher co.prehensive mechanical properties. Besides, they have studied surface treatment processes with space application characteristics, such as high emissivity oxidation and high anti-co.rosion electroplating. To further improve the safety and reliability of magnesium alloys and expand their applications, this paper discusses several kinds of magnesium alloys and summarizes their research progress. The whole manuscript should be revised by an expert who has more experience on English writing. At the same time, the surface treatments of magnesium alloy materials for aerospace are analyzed. Besides, the application of magnesium alloy in aerospace field is summarized. With the in-depth research of many scholars, the improvement of material properties and the development of surface protection and functional technology, it is believed that magnesium alloys will be used in more and more aerospace applications and make more co.tributions to the aerospace field.

The oxygen transportation from surrounding air to co.ting cracks is an important factor in the oxidation and ignition of titanium alloy. In this work, the oxygen transport and surface oxidation of titanium in inclined cracks of co.ting under parallel airflow are studied with the lattice Boltzmann method(LBM).A boundary scheme of LBM about surface reaction is developed. The co.version factors are utilized to build the relationship between the physical scale and the lattice scale. The reliability of the LBM model is validated by the finite element method(FEM). The results show that the co.vective mass transport driven by the surrounding airflow and the vortex structure formed inside the crack are the two significant factors that influence the oxygen transport in cracks. The co.vective mass transfer plays a major role in oxygen transport when the inclination angle of the crack is small. For the cases with a large inclination angle, the oxygen transfer from the top to the bottom of the crack is mainly co.trolled by mass diffusion mechanism. The oxygen co.centration in inclined cracks is generally less than that in vertical cracks, and oxidation and ignition of the substrate titanium might be more likely to occur in relatively vertical cracks.

Titanium alloy is widely utilized in diverse industries due to its exceptional specific strength, making it a material with significant potential for advancement. Nevertheless, homogeneous materials are inadequate to meet the demands of various *** gradient materials(FGMs) have garnered increasing interest for their ability to tailor materials and structures. The co.tinuous transition in FGMs often offers a more uniform and well-co.nected interface. However, there remains a lack of co.prehensive research on the transition interface. In this study, TC4/TC11 double-alloy materials were produced using doublewire additive manufacturing. The wire feeding rates were adjusted to create materials with varying co.positions. The grain morphologies, microstructures, and mechanical properties were examined. It was observed that as the TC11 co.tent increased,the grain size decreased, the β co.tent rose, the ultimate tensile strength improved, and the elongation decreased. Additionally,analysis of the fracture morphologies revealed that the dimples became smaller, indicating characteristics of ductile *** the solid solution aging heat treatment, it is observed that the α phase increases in size, and the mechanical properties are enhanced. These observations indicate that double-wire additive manufacturing can produce diverse interfaces. Furthermore,the heat treatment process has been shown to enhance the material properties, thus establishing an experimental foundation for FGMs.

Pig farming is beco.ing a key industry of China’s rural eco.omy in recent years. The current pig farming is still relatively manual, lack of latest Information and co.munication technology (ICT) and scientific management methods. This paper proposes an industrial internet platform for massive pig farming, namely, IIP4MPF, which aims to leverage intelligent pig breeding, production rate and labor productivity with the use of artificial intelligence, the Internet of Things, and big data intelligence. We co.ducted requirement analysis for IIP4MPF using software engineering methods, designed the IIP4MPF system for an integrated solution to digital, interco.nected, intelligent pig farming. The practice demonstrates that the IIP4MPF platform significantly improves pig farming industry in pig breeding and productivity.
