Advanced Refractory Metals’ Post

❓ Is it possible to obtain spherical powder from highly volatile alloy? To be exact - a Mg-7.5Li-3Al-1Zn powder. ✅ It turns out the answer is yes 🔬 For the research described in the article below, we used rePOWDER induction module to produce powder from the feedstock created out of AZ31B alloy smelted with 7.5 wt.% high-purity Li. 📊 What's most important for the research is that after the atomization, the amount of Li and Zn in the alloy powder remained unchanged, proving the rePOWDER system's capabilities. 📄 You can read more about the research in the article: https://lnkd.in/gZS428ri ✉ Or you can contact Tomasz Choma, Bartosz Moronczyk, or Jakub Ciftci directly, for more information. 🤝 Thank you Anna Dobkowska for our cooperation and trust in our possibilites to atomize your magnesium alloys modified with lithium! #metalpowder #magnesium #lithium #zinc #volatile #alloys #3dprinting #rnd #AMAZEMET #research #researchanddevelopment #AM #metalAM #additivemanufacturing #powder #powders #powdermetallurgy #materials #materialsscience #materialsengineering #metals #metal3dprinting #ultrasonicatomization

In our latest work with Dr. Abdollah Bahador, and Prof. Katsuyoshi Kondoh, we've managed to turn titanium and molybdenum powders into exceptionally strong and tough alloys by a sintering and hot-extrusion process; with up to three times the strength of pure titanium (~1500 MPa), and comparable ductility (>10% to failure). Importantly, this is entirely achieved with ONLY solid state processes — completely eliminating the tremendous energy cost required to melt and cast molybdenum (over 2600°C). Such powder metallurgy technologies offer a sustainable and cost-effective alternative to conventional Ti-6Al-4V, and is highly desirable amidst recent concerns surrouding stategic risks to the vanadium supply.

This approach allows researchers to make alloys in just 30 minutes~1 hour through a simplified process and with only a small amount of material, enabling high quality research in time and cost effectively. Also, it can produce alloys of various shapes (e.g. HEA(High Entropy Alloys), MMC(Metal Matrix Composites), FGM(Functionally Graded Materials), and Bi-metallic joint) by mixing up to 6 materials.

High entropy alloys challenge the traditional method of alloy formation that emphasizes specific regions of the phase diagram. Instead of focusing on the extremes, these alloys prioritize the central area, as explained by Clare Sansom. Read more here: https://lnkd.in/ePun8rFy #chemicals #chemicalindustry

High Entropy Alloys (HEAs) are attracting significant interest globally, based on the opportunity to improve performance in various applications, such as structural, high temperature stability, and corrosion environments, by means of example. Most research conducted to date has focussed on fabricating small buttons, via either melt, or blended elemental Powder Metallurgy (PM) techniques, or thin films, deposited using vapour-based techniques. Consequently, few obvious routes to volume production exist. This is especially pertinent regarding candidate alloys comprising of a combination of refractory and light-weighing elements, such as tantalum and aluminium, which are difficult to mix by conventional metallurgy techniques, due to vast differences in their melting temperatures and densities. Metalysis proprietary electrochemical technology, offers a solution to this scaling challenge. Operating in the solid state, it circumvents issues associated with traditional routes, whilst producing homogeneous alloys. The SEM images below show spherical Al20Ti20Mo10Ta10Nb20Zr20, both in the form of loose powder, and a cross section, demonstrating a consistent microstructure, rather than the presence of discrete regions of individual elements. Our GEN-2 reactors are capable of producing multi-kilogram batches for property testing and customer evaluation, where please visit our website at www.metalysis.com to learn more, and contact us to discuss your requirements. #highentropyalloys #powdermetallurgy #advancedmaterials #tantalum #niobium

🌟 High Carbon Silicon vs. Other Ferro Alloys: A Comparative Overview 🌟 In the world of metallurgy, the choice of ferroalloy can significantly impact the quality and performance of the final product. Today, let's delve into the characteristics and applications of High Carbon Silicon (HCSi) compared to other commonly used ferroalloys. 🔍 What is High Carbon Silicon? High Carbon Silicon typically contains 60-80% silicon and 10-25% carbon. It's recognized for its ability to enhance the strength and wear resistance of steel, making it a valuable addition in various industrial applications. Key Comparisons: Composition: HCSi: Rich in silicon and carbon, perfect for high-strength applications. Ferro Manganese (FeMn): Contains 70-80% manganese, primarily used for deoxidizing and improving toughness in steels. Ferro Chrome (FeCr): Composed of 50-70% chromium, essential for stainless steel production and corrosion resistance. Ferro Silicon (FeSi): Contains 15-90% silicon, widely used as a deoxidizer in steelmaking. Applications: HCSi: Ideal for producing high-strength and wear-resistant steels, enhancing machinability, and improving the quality of cast iron. FeMn: Crucial for carbon and stainless steels, enhancing hardness and impact resistance. FeCr: Key in the production of stainless steels and superalloys, providing high corrosion resistance. FeSi: Commonly used as a deoxidizer in steelmaking, improving casting quality. Performance Characteristics: HCSi: Offers superior strength and toughness but requires careful management to prevent brittleness. FeMn: Improves ductility and wear resistance, essential for structural applications. FeCr: Provides exceptional resistance to oxidation and corrosion, suitable for high-temperature applications. FeSi: Effectively reduces harmful oxides in steel, enhancing overall quality. 💡 Economic Considerations: While HCSi may come at a higher price, its performance benefits can lead to cost savings in the long run, especially in high-performance applications. Understanding the strengths and limitations of each ferroalloy helps manufacturers select the right materials for their specific needs. As the demand for high-quality steel and alloys continues to grow, the role of high carbon silicon and other ferroalloys will remain pivotal in achieving superior material properties. What are your thoughts on the role of HCSi in modern metallurgy? Let’s discuss! #FerroAlloys #HighCarbonSilicon #Steelmaking #Metallurgy #MaterialScience #Foundry

Tantalum (Ta) has wide industrial use for its unmatched corrosion resistance in harsh chemical environments, biocompatibility, and prominent use in electrolytic capacitors. While Ta and its alloys have also found use in high temperature structural applications and biomedical implants, it is relatively expensive and thus challenging to justify the material waste generated during traditional machining to create complex components. Moreover, Ta's high melting point precludes the use of casting as a fabrication method; instead, conventional powder metallurgy is used with various post-processing steps to generate simplistic shapes. https://lnkd.in/gR6JZFSm #tantalum #corrosionresistance
