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

SSAB and Sandvik are joining forces to use Artificial Intelligence (AI) in the whole life cycle of Steel Production (US)

SSAB and Sandvik Materials Technology are joining forces to find the best ideas on how to track steel products during their whole life cycle.

Today the SmartSteel Innovation Challenge is launched, an initiative by SSAB and Sandvik Materials Technology looking to find new brilliant ideas on what a future steel fingerprint could be made of. Is it digital, does it use artificial intelligence, is it a chemical solution, or could it be mechanics? Companies and research groups of all sizes are welcome to participate, and the winner will get the chance to develop the idea in a long-term partnership with SSAB and Sandvik Materials Technology, with access to vast business knowledge and international customer Continue reading

McNAIR Center for Aerospace Innovation and Research Adds Metal Alloys to its Fabricating Capabilities (US)

In just one year the university’s McNAIR Center for Aerospace Innovation and Research has nearly doubled in size, taking under its wing new laboratories for drone design, combustion research and a data analytics program focused on Army helicopter maintenance. The center’s 3D printing laboratory has added metal alloys to its fabricating capabilities, and a virtual design space will soon showcase McNAIR’s capabilities in digital twin design and virtual and augmented reality environments. The center now occupies about 35,000 square feet of laboratory and administrative space near the College of Engineering and Computing. On Sept. 26, the center will  host a one-day showcase of its research activities in composites, digital transformation, predictive analytics, 3D printing, combustion and unmanned vehicles.

“Our focus on design, manufacturing and digital transformation is now connecting us with aerospace companies like never before.”

Abdel Bayoumi, McNAIR Center director

When the McNAIR Center took flight about five years ago, its initial research equipment included an Ingersoll fiber

MetalDays 2018 – l’événement de l’année en métallurgie ! (FR)

Pour sa 4e édition, les MetalDays seront les 07 et 08 novembre 2018 à l’Atrium de Chaville le lieu de rencontre et d’échange des acteurs les plus importants des industries de la métallurgie, de la transformation des métaux et de leurs usages. Regroupant les sociétés les plus représentatives et novatrices du secteur, de la PME à la multinationale, cette manifestation est le lieu de rencontre des fournisseurs et donneurs d’ordres utilisant le matériau métallique. Pendant 2 jours, se dérouleront en parallèle des conférences plénières, des tables rondes, des ateliers, des rendez-vous d’affaires et des expositions avec pour ambition d’aborder tant lesContinue reading

Aubert & Duval, la filiale du groupe ERAMET se positionne comme un acteur majeur de la filière de l’impression 3D (FR)

Aubert & Duval a mis sur pied une équipe dédiée au développement des poudres.

Acteur incontournable de la chaîne régionale, Aubert & Duval, une filiale du groupe Eramet spécialisée dans la transformation à chaud des métaux. Sur le site des Ancizes (Puy-de-Dôme), une équipe est dédiée au développement des poudres afin d’élaborer de nouvelles nuances et d’apporter un soutien technique aux équipes de production.

 “Nous sommes à un tournant industriel majeur,  Les développements liés à la fabrication additive s’intensifient. Nos clients, notamment dans l’aéronautique et l’énergie, lancent en 3D de plus en plus de pièces de petite et moyenne dimensions réalisées actuellement en fonderie. Nous compléterons si nécessaire les capacités de production pour les adapter à leurs besoins futurs.”

Olivier Dubois, le directeur de la business unit poudres métalliques

Aubert & Duval – Groupe ERAMET

Une vision que partage Constellium. “Au départ, la fabrication additive est apparue comme une menace pour les produits que nous réalisons, notamment à Issoire (Puy-de-Dôme). Mais notre métier étant de fabriquer des alliages à haute valeur ajoutée, nous voyons là désormais des opportunités à saisir. Nous sommes en train de développer de nouveaux alliages, en particulier pour la filière Auvergne-Rhône-Alpes, pour élaborer des produits capables de conserver les propriétés de l’aluminium et de s’adapter à la fabrication additive”, explique Bruno Chenal, directeur de la stratégie et de l’innovation chez Constellium.Continue reading

Developing and testing new steel alloys will be up to 100 times faster in the Industry 4.0 (US)

Chemical analysis of steel – Dr James McGettrick of Swansea University, with an X-ray Photoelectron Spectrometer. This analyses the extra nanolayers which are added on top of steel, for example to improve adhesion or resistance to corrosion.

Developing and testing new steel alloys will be up to 100 times faster, allowing new products to reach market more quickly, thanks to £7 million of funding announced for a ‘virtual factory’ being developed by Swansea University, in partnership with Tata Steel and WMG, at the University of Warwick. Steel is the most widely used structural material in the world.It is at the heart of major manufacturing sectors such as the car industry, construction, packaging and defence. It is indispensable for national infrastructure such as transport, communications and energy, and for high-tech uses in energy-positive buildings to wind turbines and electric vehicles. “This project is a huge boost for innovation as it massively speeds up the development of new alloys.It means steel producers can deliver new and betterContinue reading

POSCO, Korea’s largest steelmaker, has valued the importance of talented people for the past five decades since its founding in 1968. Its management philosophy is devoted to nurturing talented individuals. To enhance job competency of its employees, POSCO has operated a training institute since 1969 while the group was busy constructing its steel mill. To strengthen its competitiveness, POSCO recently announced it will spend 45 billion won ($40.45 billion) over the next five years and hire an additional 20,000 employees by 2023. POSCO said creating 20,000 jobs is a 190 percent increase compared to the steel maker’s recruiting performance of the past five years, in which it hired about 7,000 employees. “As POSCO has valued the importance of talented individuals since its founding, the recruitment plan is to secure a growth engine for the group in the era of the Fourth Industrial Revolution,” the steelmaker said. POSCO said hiring moreContinue reading

ArcelorMittal vend ses aciers en ligne (FR)

Lancée en janvier 2018, la plateforme E-Steel permet au géant de la métallurgie de vendre 20 % de ses produits en France online.

Au départ, seule l’agence ArcelorMittal de Colomiers, qui a lancé le concept en 2017, et sept autres agences en France (Caen, Langon, La Roche-sur-Yon, Reims, Rennes, Rouen et Savigny-le-Temple) avaient mis leurs stocks à disposition des clients via un site d’e-commerce. Tubes carrés en inox, poutrelles en acier, barres plates en aluminium, tôles, plaques : l’éventail des produits était large. Six mois après son lancement, ArcelorMittal vient de tirer un premier bilan de cette nouvelle façon de vendre de l’acier. Et il est positif, selon le Continue reading
