Japanese researchers identified new alloy that can withstand ultra-high temperatures and pressure (US)

AsianScientist (Oct. 9, 2018) – A research group in Japan has identified a metal capable of withstanding constant forces at ultrahigh temperatures. Their findings are published in Scientific Reports. Heat engines are key to the future of harvesting energy from fossil fuels. Creep behavior—or a material’s ability to withstand forces under ultrahigh temperatures—is an important factor for heat engines since increased temperatures and pressures lead to deformation. Understanding a material’s creep can help engineers construct efficient heat engines that can Continue reading

Industeel mise sur le «Savoir Faire» et le «Savoir Fier» de ses employés (FR)

Quand on travaille à l’aciérie ou à la tôlerie, on ne sait pas forcément pour qui. Alors ce jeudi, Industeel a rassemblé et mélangé ses employés et donné la parole à ses spécialistes marketing des aciers spéciaux. 

Il y a une chance sur deux pour que les voitures du Président de la République soit blindée avec des aciers «made in Creusot» élaborés par Industeel, groupe ArcelorMittal. Une chance sur deux pour la voiture présidentielle, mais aussi pour tout ce qui concerne les protections blindées. Notamment pour l’armée française. C’est une des applications des aciers spéciaux élaborés au Creusot que la direction d’Industeel a voulu montrer à ses employés, jeudi 18 octobre à L’arc. Deux grosses vagues d’employés ont investi le petit théâtre de L’arc. Notamment des employés venus de l’aciérie du Breuil ou de la tôlerie. Cédric Chauvy, directeur de l’établissement du Creusot, est Continue reading

Les questions d’environnement et de mobilité figurent au centre de la recherche et développement du groupe sidérurgique ArcelorMittal.

Le campus de R&D de Maizières-lès-Metz (Moselle), le plus important du groupe, est en première ligne pour la mise au point de nouveaux produits et des processus industriels pour les produire, a expliqué son directeur Frédéric Grein, vendredi, lors d’une visite du site qui fête ses 60 ans. L’objectif est «porter les améliorations et les innovations sur le terrain» pour «aider les usines du groupe à améliorer leurs paramètres de rendement, de qualité et de productivité», résume-t-il. Et il faut ensuite «aider les clients à utiliser au mieux les nouveaux produits», ajoute-t-il. La maîtrise des émissions de CO2 constitue l’un des premiers impératifs pour le producteur d’acier et répond aussi à

ThyssenKrupp CEO calls for restraint on global steel production (US)

The World Steel Association predicts a slowing of demand next year as China’s growth declines

Steel makers in China and the rest of the world need to do more to reduce overcapacity, according to Guido Kerkhoff, chief executive officer of Germany’s ThyssenKrupp. While China has made good progress in curbing over-production, there’s room for even more cuts, Mr Kerkhoff said in Shanghai on Saturday. The biggest steel making nation has reshaped the industry in the past three years by closing plants, tightening environmental controls andContinue reading

US Army Develops New Gold-Silver Alloy for Military use (US)

  • Army researchers are using metallic alloys to lighten the load and enhance the power of Soldier devices used on the battlefield.
  • This research was recently featured on the cover of Advanced Optical Materials.

ADELPHI, Md. (Oct. 2, 2018) — What happens when gold and silver just don’t cut it anymore? You turn to metallic alloys, which are what Army researchers are using to develop new designer materials with a broad range of capabilities for our Soldiers. This is exactly what scientists Dr. David Baker and Dr. Joshua McClure from the U.S. Army Research Laboratory are doing to lighten the load and enhance the power of Soldier devices used on the battlefield. Their research, conducted in collaboration with Prof. Marina Leite and Dr. Chen Gong atContinue reading

US Navy and Lockheed Martin Put Artificial Intelligence Into 3D Printers (US)

The drive to push 3D printing into the field is getting a boost from an unexpected ally — artificial intelligence that can monitor robots and teach them how to do a better job.

One thing about airplanes—especially ones that fly from aircraft carriers, where they’re battered by saltwater and tough deck landings—is that they need lots of spare parts that are not always on hand. Instead of flying in new parts, though, future Navy ships may be able to make new ones to order. Picutre an intelligent, laser-wielding robot that can analyze the damage and 3D-print the needed titanium alloy parts from an onboard supply of metallic dust. This is one glimpse of the future proposed by the Office of Naval Research (ONR), which today announced a two-year, $5.8 million contract to create a new generation of super-smart 3D printers. The printers would not onlyContinue reading

ATI and NLMK Sign Carbon Steel Hot-Rolling Conversion Agreement (US)

Allegheny Technologies announced Thursday it has signed an agreement with NLMK USA to process its steel on ATI’s hot-rolling mill in Harrison. NLMK USA, a subsidiary of a Russian steel company, has production sites in Indiana and Pennsylvania. It produces flat-rolled steel used in manufacturing, and supplies steel coils to the construction, automotive, pipe and tube, and heavy equipment industries in the United States. The agreement for ATI to hot-roll NLMK’s carbon steel slabs into coils runs through December 2019. “Slab shipments to ATI will begin immediately and increase to anticipated production levels in the first quarter of 2019,” ATI said in a release. Neither company is disclosing the dollar value of the agreement, ATI spokeswoman Natalie Gillespie said. ATI’s $1.1 billion steel mill is now Continue reading

The Tungsten’s Bullet That Swims Through Water (US)

Nammo’s penetrators, both for vehicles and other types of armor piercing ammunition, are made out of a super tough tungsten alloy, also known as wolfram. More than two times as heavy as steel, it has the second highest melting point of any element, making it ideal for use in armor piercing ammunition. For some ammunition types, including the 25 mm APEX for the F-35, tungsten is mixed with carbon, creating tungsten carbide. This makes the penetrators harder, but also more brittle, allowing them to fragment once they have penetrated the armor, causing added damage inside the target

The U.S. Navy and Norwegian defense group Nammo have developed a super-cavitating bullet that can travel through water. While traditional ammunition is either stopped or deflected when it hits water, Nammo’s 30 mm Swimmer (APFSDS-T MK 258 Mod 1) swims straight through it. Nammo says the U.S. Army and the U.S. Navy are now adopting the Swimmer for use from many platforms, includingContinue reading
