A high-entropy alloy with hierarchical nanoprecipitates and ultrahigh strength (US)

High-entropy alloys (HEAs) are a class of metallic materials that have revolutionized alloy design. They are known for their high compressive strengths, often greater than 1 GPa; however, the tensile strengths of most reported HEAs are limited. Here, we report a strategy for the design and fabrication of HEAs that can achieve ultrahigh tensile strengths. The proposed strategy involves the introduction of a high density of hierarchical intragranular nanoprecipitates. To establish the validity of this strategy, we designed and fabricated a bulk Fe25Co25Ni25Al10Ti15 HEA to consist of a principal face-centered cubic (fcc) phase containing hierarchical intragranular nanoprecipitates. Our results show that precipitation strengthening, as one of the main strengthening mechanisms, contributes to a tensile yield strength (σ0.2) of ~1.86 GPa and an ultimate tensile strength of ~2.52 GPa at room temperature, which heretofore represents the highest strength reported for an HEA with an appreciable failure strain of ~5.2%.

The traditional alloy design concept combines one or two principal elements with additional minor elements, an approach that restricts the development and application of alloys due to the limited compositional space explored (1). Thus, to enable the pursuit of alloys with special microstructures and properties, such as high strength, new design concepts are needed. Recently, a brand new class Continue reading

Saarstahl’s CEO: “We want to remain the market leader” (German)

Völklingen. Saarstahl is not only the leading company in Völklingen, but has a worldwide reputation. The steel cookers not only want to maintain their leading position, but also expand it further, says Martin Baues, Chief Technology Officer.

When Martin Baues slept in his nursery in his Wehrden home, he heard the saw in the steelworks. Today, the blast furnace group is part of the Unesco World Cultural Heritage and the 58-year-old technical director in the still active part of the former Völklinger Hütte, Saarstahl Continue reading

Hayange: Les hauts-​​fourneaux ne redémarreront pas (FR)

Philippe Darmayan a clairement laissé entendre que la production d’acier n’avait plus d’avenir en Lorraine. «Il n’y a pas de suspense à entretenir. Des raisons structurelles nous ont amenés à concentrer nos hauts-fourneaux sur les sites côtiers de Dunkerque et de Fos. Et je ne vois pas ce qui pourrait changer d’ici décembre», 

Les hauts fourneaux de Hayange n’ont pas vocation à rouvrir. Le président d’ArcelorMittal France, Philippe Darmayan, vient de le confirmer ce jeudi après-midi à Thionville où il était de passage. Le doute était jusqu’ici permis. Il ne l’est plus : les hauts fourneaux de la vallée de la Fensch sont définitivement morts. Hier, à l’occasion d’un déplacement à Thionville, Philippe Darmayan, président d’ArcelorMittal France, a confirmé entre les lignes que les unités de production d’acier Continue reading

Le Ministre des finances luxembourgeois visite le centre de recherche d’ArcelorMittal à Esch/Alzette (FR)

Lors de sa visite, le ministre a découvert les domaines d’intervention du Centre de recherche et, plus particulièrement, les produits phares du groupe ArcelorMittal. Ce fut également une occasion pour parler, ensemble avec les intervenants, sur les implications de la digitalisation dans l’industrie sidérurgique. Le ministre a également visité des installations dédiées à la métallographie. Il s’agit de laboratoires où sont notamment analysées les structures des aciers via un Continue reading

Aubert et Duval s’engage 7 ans de plus avec Framatome et sa «forge de l’excellence» (FR)

C’est un accord en forme de reconnaissance qu’Aubert et Duval a signé, jeudi, avec Framatome au Creusot. Les presses de la forge vont être mise à contribution pour des pièces à très très haute valeur ajoutée.

Le travail des lingots creux n’est pas la seule spécialité de la Forge du Creusot et de Framatome. Une nouvelle preuve en a été apportée ce jeudi en fin d’après-midi, quand Jérôme Fabre, président d’Aubert et Duval a signé un contrat avec David Emond et David Haguet, respectivement directeur en charge des composants et directeur du site du Creusot de Framatome. Un contrat qui, soulignons le avec le sourire, réhabilite le septennat qui a disparu de la constitution de la 5ème République… Un accord de 7 ans qui aura donc été signé le jour du 50ème anniversaire de la Continue reading

GE Aviation’s Celebrates its 30,000th 3D-printed fuel nozzle tip for the LEAP engine (US)

AUBURN, Alabama — GE Aviation’s plant in Auburn achieved a milestone this week — the 30,000th additively-manufactured fuel nozzle tip “grew” on a 3D printer at the facility, the industry’s first site for mass production using the additive manufacturing process.

Employees at GE Aviation in Auburn began producing the nozzle tip in 2015. More 3D printers have been added since the facility started additive production, and now, more than 40 printers are making parts from a metal powder. “This milestone isn’t just about reaching production of 30,000 fuel nozzle tips. The team should also be proud for their role in helping prove additive technology works in mass production for our business and others whoContinue reading

Trump says Pentagon to produce lithium sea-water batteries (US)

A senior U.S. administration official said new steps to ensure U.S. military’s supplies include an effort to build up stockpiled reserves of scarce materials and expand U.S. capabilities to manufacture products such as lithium sea-water batteries.

WASHINGTON (Reuters) – President Donald Trump said on Friday there was a shortfall in the U.S. defense industrial base relating to lithium sea-water batteries and the Defense Department would purchase equipment for pilot production of the batteries that are critical for anti-submarine warfare. A Pentagon-led report issued on Friday that seeks to mend weaknesses in core U.S. industries vital to national security included recommendations such asContinue reading
