While titanium implants such as artificial hips can greatly improve patients' lives, they're also subject to serious bacterial infections. An experimental new antibacterial titanium alloy, however, could make such problems a thing of the past.Continue ReadingCategory: Medical, ScienceTags: Washington State University, Implant, Titanium, Alloy, Antibacterial
A simple alloy has claimed the crown for toughest material ever recorded. In a new study, a team led by researchers at Berkeley Lab ran the alloy through a series of tests and discovered not only its incredible toughness, but high strength and ductility that actually improve in colder temperatures, unlike most known materials.Continue ReadingCategory: Materials, ScienceTags: Alloy, tough, Lawrenc
Engineers at Monash University have developed a new 3D-printable titanium alloy with a unique microstructure that makes it ultra-strong. Not only is it stronger than most other forms of titanium, but it has the highest strength-to-weight ratio of any 3D-printed metal ever made.Continue ReadingCategory: Materials, ScienceTags: Materials, Titanium, Alloy, Metals, Monash University, Manufacturing, 3
With new manufacturing techniques comes the opportunity for brand new metal alloys with a huge range of possible properties. A team of researchers has now developed a new 3D-printable alloy with a specific nanostructure that makes it ultra strong and ductile.Continue ReadingCategory: Materials, ScienceTags: Alloy, Metals, new material, 3D Printing, Laser, Georgia Tech, University of Massachusetts
Scientists experimenting with the makeup of metal alloys used for medical implants have made a significant breakthrough, resulting in a biomaterial with supreme flexibility and wear resistance. The team's new superelastic alloy overcomes some key safety issues and offers the kind of strain recovery and durability needed for long-term stints in the human body.Continue ReadingCategory: Medical, Sci
Researchers at Northwestern University in Illinois have demonstrated the world's smallest remote-controlled walking robot, at just half a millimeter wide. Such tiny machines can bend, twist, crawl, walk, turn and jump without hydraulics or electricity.Continue ReadingCategory: Robotics, TechnologyTags: Northwestern University, Crabs, Robotics, Remote-Control, Miniature, Shape Memory Alloys
With a view to constructing more durable components that can withstand the very harsh environments in and around aircraft and jet engines, NASA researchers have developed a novel metal alloy with an impressive set of qualities at extreme temperatures. These include incredible strength that is double that of current state-of-the-art alloys, and far greater flexibility, which the team says could le
City University of Hong Kong researchers have accidentally discovered a first-of-its-kind alloy that retains its stiffness instead of softening as the temperature rises. Indeed, high-entropy Elinvar appears to get stiffer and springier as temperatures approach 1,000 K (727°C, 1,341 °F). No other known metals have been found to behave this way.Continue ReadingCategory: Materials, ScienceTags: Meta
Researchers from the Chinese Academy of Sciences have found that Earth’s inner core may be stranger than we thought. Rather than a plain solid, new simulations suggest it exists as a superionic state of matter, partway between a liquid and a solid.Continue ReadingCategory: ScienceTags: Earth, Earth core, Planet, Chinese Academy of Sciences, Alloy
As useful as steel is, its main weakness may be its vulnerability to corrosion. Researchers in Korea have now developed a new alloy coating that boosts steel’s resistance to rust, by adding a simple extra step in the surface treatment.Continue ReadingCategory: Materials, ScienceTags: Corrosion, Anti-Corrosion, Marine, Materials, Steel, Alloy, korea, Silicon, Aluminum, Magnesium, New Atlas Audio is a social bookmarking place where you can share, find & discuss the best news around on most topics.
