This approach mitigated the limitations of brittle intermetallic compound (IMC) formation and microcracks, resulting in a robust joint with improved tensile strength and hardness. In-situ alloying of blended elemental powders via laser directed energy deposition (DED) was used to fabricate a high-strength lamellar high-entropy alloy (HEA) with excellent ductility. The DED-processed HEA exhibited a lamellar structure with alternating molten pools and heat affected zones, providing outstanding mechanical properties for structural applications. Additionally, the additive manufacturing of titanium alloys through laser melting deposition with the addition of multi-element Fe–Cr–Ni–Mo resulted in enhanced strength and uniform ductility. The localized homogenization of CP-Ti and 316L alloy melts produced a microstructure that improved the mechanical properties of the alloy. Finally, friction screw extrusion additive manufacturing (FSEAM) was used to deposit thin layers of AA6060T6 aluminum alloy, resulting in solid walls with promising mechanical properties and a fine microstructure.

What are the most common pipeline materials used in Europe to transport natural gas?
4 answers
The most common pipeline materials used in Europe to transport natural gas include polymer liners made from polyethylene or polyamide (nylon). These polymer liners are used to mitigate internal corrosion in natural gas pipelines. Composite liners, which incorporate one or more metallic layers that are impermeable to corrosive gases, offer better protection than polymer-only liners. Additionally, stainless steel transition sections are used in pipelines for transporting petroleum and natural gas. These transition sections are connected to the ends of the pipeline and ensure that the anti-corrosion properties of the welding areas are maintained, allowing for normal transportation of mediums and reducing the frequency of pipeline maintenance.
What is the effect of zirconate treatment on the plasma electrolytic oxidation of magnesium?
5 answers
The addition of zirconate treatment in the plasma electrolytic oxidation (PEO) process of magnesium has been found to have a positive effect on the corrosion resistance and abrasive resistance of the resulting coatings. The anions of the zirconate additives participate in the coating formation, influencing the microstructural features, chemical composition, and tribological behavior of the coatings. The PEO coatings prepared with zirconate additives showed better corrosion and abrasive resistance compared to other additives such as sodium silicate and sodium aluminate. The zirconate-treated coatings exhibited a reduction in the formation of detrimental defects and the growth of discharge channels and pores, resulting in thicker and denser oxide layers. However, it should be noted that the zirconate treatment may also lead to cracks and peeling at the interface between the coating and the substrate due to the mismatch of thermal expansion coefficients.

What is metal additive manufacturing?
5 answers
Metal additive manufacturing is a rapidly growing field that involves the fabrication of complex parts using a layer-by-layer approach. It allows for the production of shapes that cannot be achieved through traditional machining methods and enables the use of trabecular reinforcing structures and topological optimization for improved performance and reduced mass. Metal additive manufacturing has numerous applications in industries such as automobile, aerospace, and biomedical. One of the main advantages of metal additive manufacturing is the ability to create complex geometries that would be difficult or impossible to achieve with other manufacturing processes. However, metal parts produced through additive manufacturing may have small porosities that can affect their mechanical properties, especially fatigue performance. Post-processing techniques like hot isostatic pressing (HIP) can be used to eliminate these pores and enhance the microstructure and fatigue performance of the parts. Metal additive manufacturing is also used in the development of hard tissue biomaterials for functional bone reconstruction, with a focus on controlling the anisotropic bone microstructure.

What is the importance of galvanizing metals?
5 answers
Galvanizing metals is important for preventing corrosion and increasing the durability of steel tools in outdoor or corrosive environments. It involves coating the metal surface with a layer of zinc, which acts as a protective barrier against oxidation and other corrosive elements. Galvanizing can be achieved through various processes, such as hot dip galvanization, which involves immersing the metal in a bath of molten zinc. This creates a thin, durable, and protective coating that enhances the longevity of the metal. Different galvanizing technologies have been developed to ensure uniformity and quality of the galvanized layer. These technologies involve steps such as cleaning, degreasing, and galvanizing the metal, followed by drying and inspection. The use of specific galvanizing alloys, such as zinc-nickel and zinc-aluminum, has further improved the corrosion resistance and temperature resistance of galvanized steel products. Overall, galvanizing metals is crucial for preserving their integrity and extending their lifespan in challenging environments.

Is there asbestos in rice?
5 answers
No, there is no direct evidence to suggest that there is asbestos in rice. However, there have been concerns about the potential contamination of rice with asbestos due to the use of talc, which may contain asbestos as a contaminant. Talc is sometimes added to rice, particularly in Japan, and asbestos is a frequent contaminant of talc. Asbestos and talc are produced by the same geologic processes and occur in the same deposits. The ingestion of asbestos-contaminated talc has been associated with an increased incidence of gastrointestinal tract cancer. While rice itself has also been suspected as a potential cause of cancer, the high incidence of stomach cancer in Japan is believed to be more strongly linked to asbestos-contaminated talc on rice in the diet.
