“…As shown in Figure 9, the left side of the uppermost fibrous filament was rounded with small etched holes, and the right side was mostly irregular with large etched holes. The enlarged individual large etch holes (region 2) show that the irregular large etch holes were combined by overlapping many circular etch holes, and the type of etch holes belonged to open wide and shallow etchings, indicating the uniformity of the material 35,36 . It can also be found that there were two etch point sources inside the large etch holes in Figure 9, which were formed by overlapping two separate etch holes.…”

Incineration is an effective means of solid waste disposal, but the acidic components in the complex flue gas generated by incineration put pressure on the dust removal, which also puts higher requirements on the corrosion resistance of the filter media. In this work, aiming at the gas-solid corrosion characteristics of 316L alloy fiber filter bag, the corrosion behavior of 316L alloy fiber filter materials in halogen hydride atmosphere was studied using fixed-bed simulation corrosion experiments, and the mechanical properties of the filter materials after corrosion were analyzed. For the 316L alloy fiber filter bag, the influence of flue gas composition (O 2 and H 2 O) and its concentration on the corrosion characteristics was explored. The corrosion mechanism was studied by combining the microscopic morphology and element distribution of the filter material before and after corrosion. The results show that halogen hydride

“…Improving the mechanical properties of magnesium alloys has been a persistent challenge. To address these issues, alloy design often involves adding reinforcing elements such as Al, Ca, Zn, and Si [3][4][5][6][7][8], with magnesium-aluminum alloy being the most common alloy in practice. While some research on magnesium alloys has addressed drawbacks like low strength and flammability through the addition of rare earth elements or process improvements, the feasibility of large-scale application and complete replacement of existing methods remains uncertain [9,10].…”

Magnesium-aluminum alloy is one of the most common alloy materials in the industry, widely utilized due to its low density and excellent mechanical properties. Investigating the properties or predicting new structures through experimentation inevitably involves complex processes, which consume significant time and resources. To facilitate the discovery, simulations such as Density Functional Theory (DFT) and machine learning (ML) methods are primarily employed. However, DFT incurs significant computational costs. While ML methods are versatile and efficient, they demand high-quality datasets and may exhibit some degree of inaccuracy. To address these challenges, we employ a combination of generative model and automatic differentiation (AD), reducing the search space and accelerating the discovery of target materials. We have predicted a variety of magnesium-aluminum alloys. We conducted structure optimization and property evaluation for ten potentially valuable intermetallic compounds. Ultimately, we identified five stable structures: Mg3Al3, Mg2Al6, Mg4Al12, Mg15Al and Mg14Al2. Among these, Mg4Al12, Mg15Al and Mg14Al2 may hold higher potential for practical applications.

“…For this reason, Mg and Zn will be used with as alloy (Zn-3Cu-1Mg). Mg, Zn alloy (Zn-3Cu-1Mg) mechanical characteristics of new type stent production are preferred because it is well-suited to the body, resistant to wear, corrosion and fatigue [7][8]. In addition, Mg, Zn alloys are very useful bio-material, as they will cover the shortage of Mg and Zn over time for the human body.…”

"The stent is manufactured by traditional machining methods. This study has been carried out to improve the mechanical properties of stents produced by removing swarf. Production methods have been examined and extruded to produce a seamless cylindrical section pipe. The Mg-Zn-XX alloy used in stent production was used in this study. Extrusion mold design is made to produce stent with Mg-Zn-XX alloy. These parameters are optimized because temperature and friction values from the Extrusion parameters affect the shaping parameters of the generated stent. During optimization, the Simufact finite elements program was used. The optimization has shown that the Mg-Zn-XX alloy has the best styling results of friction of 300 o C de Coulumb 0.4. "
