Derrière Ascoval, un écosystème local (FR)

Métiers de la ferraille, services à l’industrie, tuberie voisine… : un millier d’emplois sont liés au destin de l’aciérie nordiste, selon les élus et les syndicats.

 Si tout le monde joue le jeu jusqu’au bout, Ascoval peut être sauvée et nous garderons une filière des aciers spéciaux en France », a lâché le président de la région Hauts-de-France Xavier Bertrand, à l’issue de la réunion à Bercy mercredi,  au terme de laquelle le gouvernement s’est accordé un délai d’un mois pour peaufiner le plan de reprise. De fait, au-delà de la seule aciérie nordiste et de ses 281 salariés, c’est tout un écosystème industriel qui Continue reading

Rhenium : A Critical Rare Metal for the Military Engines For Jet Fighters (US)

Roughly 52,000 kilograms, or 52 metric tons, of rhenium was produced worldwide during 2017. The United States is by far the largest consumer of this critical mineral, accounting for 42,600 metric tons, or nearly 82 percent, of last year’s global production. Nearly 80 percent of the rhenium consumed in the United States is used in superalloys vital to highly efficient jet turbine engines. “The high-temperature properties of rhenium allow turbine engines to be designed with closer tolerances, thus enabling increased thrust and higher operating efficiency,” the USGS explains. The turbine engines in older generation U.S. military aircrafts, such as the F-15 and F-16 fighters, were made from a nickel-based superalloy containing 3 percent rhenium. The turbines in newer generation fighters, such as the F-22 and F-35, contain 6 percent rhenium. The higher rhenium content alloys and limited supply pushed the price of rhenium to a high of US$10,600 per kilogram before the markets crashed in 2009.

Enormous copper-gold deposit in Alaska contains enough of this superalloy metal to supply global needs for 40 years. With a melting point of 5,756 degrees Fahrenheit and a heat-stable crystalline structure, rhenium is extremely resistant to both heat and wear. This durability makes it a vital element in superalloys used in jet and industrial gas turbine engines. “The high-temperature properties of rhenium allow turbine engines to be designed with finer tolerances and operate at temperatures higher than those of engines constructed with other materials,” the United Continue reading

Standford Innovative Artificial Intelligence Program Recreates the Periodic Table (US)

In a first step toward generating an artificial intelligence program that can find new laws of nature, a Stanford team created a program that reproduced a complex human discovery – the periodic table.

It took nearly a century of trial and error for human scientists to organize the periodic table of elements, arguably one of the greatest scientific achievements in chemistry, into its current form. A new artificial intelligence (AI) program developed by Stanford physicists accomplished the same feat in just a few hours. Called Atom2Vec, the program successfully learned to distinguish between different atoms after analyzing a list of chemical compound

Weber Metals Unveils $180 million, 60,000-ton forge press (US)

Inauguration day for the 60,000-ton closed-die forging press in Paramount, CA, October 2018.

A $180 million, 60,000-ton forge press made its debut last week at Weber Metals, Inc., a Paramount-based manufacturing division of Otto Fuchs KG of Germany. Its addition is estimated to create 200 manufacturing jobs for area residents. Company officials also noted that the state of California contributed $20 million in tax credits to the project, which currently stands as the world’s largest private investment in aerospace metal forging. “This innovative technology will literally forge the future for parts made for aircraft and spacecraft,” said Dr. Hinrich Mählmann, managing partner of OTTO FUCHS KG. “This, the world’s largest pull-down forging press, will Continue reading

Materials will lead the Energy Transition Revolution (US)

MIT Energy Initiative Director Robert Armstrong offers his perspective on the takeaways from MITEI’s annual research conference.

“From nanomaterials to metal alloys, materials are going to play a role in everything from energy production and conversion to transmission, distribution, and end use”.

MIT Energy Initiative Director Robert Armstrong

The MIT Energy Initiative (MITEI) 2018 annual research conference brought together energy researchers, policymakers, and industry members working on cutting-edge technologies and business models for the transition to a low-carbon future. Panels ranged from the latest developments in the fight against climate change to innovations for creating a better environment in which energy startups can thrive. A special segment of the conference, presented Continue reading

Arconic weighs $11 billion offer from Apollo (US)

Aluminum products maker Arconic Inc’s (ARNC.N) board of directors is mulling an $11 billion acquisition offer it received last Friday from buyout firm Apollo Global Management LLC (APO.N), according to people familiar with the matter. The offer is at a small premium to where Arconic shares are trading, adding pressure on the U.S. company to decide if it will remain independent after President Donald Trump’s imposition of aluminum tariffs drove up its costs this year and weighed on business prospects. Apollo’s offer values Arconic at between $23 and $24 per share, one of the sources said. Arconic shares ended trading on Monday at $21.45. Arconic had $6.3 billion inContinue reading

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
