Simple alloy claims crown of toughest material ever recorded
Posted by ArielTechGeek 355 days ago (https://newatlas.com)
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
New titanium alloy has highest specific strength of any 3D-printed metal
Posted by ArielTechGeek 436 days ago (https://newatlas.com)
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

New superelastic metal alloy bends it like bone for safer implants
Posted by ArielTechGeek 548 days ago (https://newatlas.com)
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
Smallest-ever remote-control walking robot uses shape-memory alloy
Posted by ArielTechGeek 554 days ago (https://newatlas.com)
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
Novel NASA alloy offers "remarkable" properties at extreme temperatures
Posted by ArielTechGeek 590 days ago (https://newatlas.com)
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
Super-elastic alloy is first known metal to get springier as it heats up
Posted by ArielTechGeek 654 days ago (https://newatlas.com)
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
Earth's inner core is a strange superionic iron alloy, study suggests
Posted by ArielTechGeek 657 days ago (https://newatlas.com)
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
New alloy coating builds an inner shield to stop steel rusting
Posted by ArielTechGeek 691 days ago (https://newatlas.com)
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
