Why selecting CoCrFeNi and CoCrFeMn bases for producing HEAs?
Best insight from top research papers
Selecting CoCrFeNi and CoCrFeMn bases for producing High-Entropy Alloys (HEAs) is advantageous due to their unique properties and potential applications. CoCrFeNi HEAs, when doped with nitrogen, exhibit increased strength attributed to solid solution strengthening, although ductility decreases due to hindered twin formation . On the other hand, CoCrFeNiMn HEAs demonstrate high hardness and oxidation resistance, making them suitable for coatings on low-carbon steel surfaces . Additionally, computational simulations suggest that AlCoxCrFeNi HEAs with optimal mechanical properties have a Co content range of 0.5 to 0.7, highlighting the versatility and tunability of these alloys . Therefore, the selection of CoCrFeNi and CoCrFeMn bases for HEAs offers a wide range of mechanical and structural advantages, making them promising candidates for various industrial applications.

What are technologies to use at HEIs?5 answersHigher Education Institutions (HEIs) utilize a variety of technologies to enhance educational delivery. These technologies include Electronic Learning Management Systems (ELMS) for planning, distribution, and evaluation of learning processes. Additionally, HEIs are incorporating cutting-edge technology to set up learning and administrative platforms, supporting various learning modalities such as on-site, synchronous online, and asynchronous online through the HyFlex mode of delivery. Professors in HEIs are increasingly using ICT resources like hardware, software, and digital educational tools to enrich the educational process, with a focus on tools like desktop PCs, laptops, and smartphones. Furthermore, the implementation of contemporary educational technology in HEIs is guided by a framework incorporating dimensions like technology, stakeholder perceptions, academic discipline, success metrics, and theoretical frameworks to ensure effective integration and utilization of technology in pedagogical practices.
How to make CoCrFeMnNi HEA?5 answersCoCrFeMnNi high-entropy alloys (HEAs) can be made using different methods. One approach is to use gas atomized powders of CoCrFeMnNi alloy and AlN to prepare AlN–CoCrFeMnNi cermets through ball milling and hot pressing sintering. Another method involves blending elemental powders of Co, Cr, Fe, Mn, and Ni and using selective laser melting (SLM) to fabricate bulk samples of CoCrFeMnNi HEA. Laser metal deposition (LMD) on highly deformed equiatomic CoCrFeMnNi HEA sheets can also be used to fabricate a multi-gradient heterostructured CoCrFeMnNi HEA. Additionally, direct energy deposition (DED) of pre-ball milled powders can be employed to fabricate CoCrFeMnNi+B4C high-entropy composites (HECs). Reduction of a mixture of Co, Cr, Fe, Mn, and Ni oxides can also be used to synthesize CoCrFeNiMn HEA.
How much amount of hesperidin used in cellulose acetate scaffold for bone regeneration?5 answersThe amount of hesperidin used in cellulose acetate scaffold for bone regeneration varied in the studies. In one study by Jeon et al., they prepared gellan gum hydrogel scaffolds with different amounts of hesperidin (0, 1, 2, 4 mg) for cartilage regeneration. Another study by Shaban et al. used HA/BER and HA/ME composites mixed with cellulose acetate nanofibers, but the specific amount of hesperidin was not mentioned. Therefore, the exact amount of hesperidin used in cellulose acetate scaffold for bone regeneration is not clear from the available abstracts.
What are the advantages and disadvantages of HEA coatings?5 answersHEA coatings have several advantages, including high hardness, wear resistance, oxidation resistance, thermal stability, and excellent mechanical, physical, and chemical properties. These coatings are also effective diffusion barriers and show superior performance in terms of corrosion resistance and protection against wear, heat, and environmental factors. HEA coatings can be easily deposited using reactive coating technology, allowing for the deposition of nitride, carbide, oxide, and carbonitride coatings with outstanding properties. However, it is important to note that not all HEA-based coatings exhibit these superior properties, as the number of elements in the composition can compete with other factors that influence the structure and properties of the coating. Therefore, careful selection of composition and deposition parameters is crucial for achieving the desired properties in HEA coatings.
What is the electrochemical performance of CoCrFeMnNi compound in different temperature?4 answersThe electrochemical performance of the CoCrFeMnNi compound in different temperatures has been investigated in several studies. It has been found that the corrosion resistance of the compound initially increases and then decreases with increasing annealing temperature. The presence of twins in the compound further facilitates the formation of pits, leading to increased corrosion. The deformation mechanism of the compound is dominated by a synergistic effect of twinning and dislocation pile-up, which contributes to a higher yield strength and strain hardening rate at cryogenic temperatures. The electrodeposition of the compound on an aluminum support is more difficult and results in lower corrosion resistance compared to deposits on a copper support. The addition of SiC nanoparticles to the compound improves its mechanical properties but reduces its corrosion resistance in chloride environments.
How did research productivity benefit the HEIs?1 answersResearch productivity has benefited Higher Education Institutions (HEIs) by increasing their contribution to the body of knowledge and promoting academic excellence. The research output helps in unlocking hidden growing topics and identifying research themes. It also aids research administrators and management in developing policies to increase research productivity. Additionally, research productivity is crucial for the overall economic development of a country, as it leads to knowledge, innovation, and technology production. Private HEIs, even without full state funding, have made considerable contributions to research output and R&D productivity. Furthermore, increasing research productivity is essential for academic health centers to maintain their academic excellence, despite faculty members having limited time for research due to clinical revenue generation. In the field of marketing, enhancing research productivity requires addressing issues such as inadequate training, sub-optimal concentrations of research activity, and competing commitments. Overall, research productivity is a key indicator of the intellectual vigor of academic disciplines and plays a vital role in the success and survival of HEIs.
