Alloy

Introduced in 2004, high-entropy alloys (HEAs) are alloys composed of multiple principal elements in nearly equiatomic proportions. Their unique chemical composition results in a high degree of chemical disorder, i.e. entropy, and produces…

Mumbai: Five years after foraying into the steel business, metals and mining magnate Anil Agarwal will review his play in the alloy sector. On Friday, his India-listed firm Vedanta said it has engaged advisers to assist in the review. The…

Scientists have measured the highest toughness ever recorded, of any material, while investigating a metallic alloy made of chromium, cobalt, and nickel (CrCoNi). Not only is the metal extremely ductile -- which, in materials science, means…

Clean hydrogen energy is a good alternative to fossil fuels and is critical for achieving carbon neutrality. Researchers around the world are looking for ways to enhance the efficiency and lower the cost of hydrogen production, particularly…

Palladium -- a precious metal -- is attracting attention as a fuel cell electrocatalyst, which requires metals with high electrocatalytic activity. Because of the high cost of palladium, creating a palladium-zinc alloy should improve…

India has initiated a probe to ascertain if a spurt in imports of Ferro Molybdenum, which is used in steel, nickel, and cobalt alloys, from South Korea is hitting the domestic producers. According to a notification issued by the Directorate…

A team of researchers at the University of Massachusetts Amherst and the Georgia Institute of Technology has 3D printed a dual-phase, nanostructured high-entropy alloy that exceeds the strength and ductility of other state-of-the-art…

Nonthermal plasma (NTP) is used to activate CO2 molecules for hydrogenation into alternative fuels at low temperatures, also enabling the conversion of renewable electricity to chemical energy. Researchers from Tokyo Tech combined…

Laser powder bed fusion, a 3D-printing technique, offers potential in the manufacturing industry, particularly when fabricating nickel-titanium shape memory alloys with complex geometries. Although this manufacturing technique is attractive…

Funded by the National Science Foundation's Designing Materials to Revolutionize Our Engineering Future (DMREF) Program, researchers from the Department of Materials Science and Engineering at Texas A&M University used an Artificial…
