Artificial Intelligence Reveals New Class of High Entropy Alloys (US)

Lehigh researchers use data analytics and experimental microscopy to discover new high-entropy alloys, validating novel approach to new materials search

A new method of discovering materials using data analytics and electron microscopy has found a new class of extremely hard alloys. Such materials could potentially withstand severe impact from projectiles, providing better protection of soldiers in combat. Lehigh researchers describe the method and findings in an article, “Materials Informatics For the Screening of Multi-Principal Elements and High-Entropy Alloys,” published in Nature Communications. “We used materials informatics—the application of the methods of data science to

Fraunhofer Engineers use Artificial Intelligence to Discover new Superalloys (US)

By means of laser powder build-up welding, components made of different materials can be integrally manufactured. Thus, specific materials can be placed exactly where their properties are required. This offers, for example, the prospect of lighter, better and cost-reduced blades for gas turbines

Fraunhofer IWS engineers have refined laser powder buildup welding over decades in order to allow more materials to be applied in additive manufacturing. In this procedure, a system feeds various filler powders into a process zone. There, a laser melts the powder and deposits it on a workpiece surface. As a result, the desired part is generated in a layer by layer process. “One of the advantages of this additive procedure is that we can adapt the process very flexibly to the requirements of high-performance materials,” explains Fraunhofer IWS project administrator Michael Müller. In this way it is also possible, for example, to print nickel-based alloys that are difficult to weldContinue reading

A New Manufacturing Process to eliminate multiple steps in extrusion for Aluminum Alloys (US)

June 18, 2019 – An advanced manufacturing process to produce nanostructured rods and tubes directly from high-performance aluminum alloy powder — in a single step — was recently demonstrated by researchers from the Pacific Northwest National Laboratory. Using a novel Solid Phase Processing approach, the research team eliminated several steps that are required during conventional extrusion processing of aluminum alloy powders, while also achieving a significant increase inContinue reading

Allegheny (ATI) Divests Titanium Investment Castings Business (US)

PITTSBURGH-Allegheny Technologies Incorporated (NYSE: ATI) today announced it has reached a definitive agreement to sell its Cast Products business to Consolidated Precision Products Corp. (CPP) of Cleveland, OH. CPP operates 16 global facilities manufacturing products primarily for the aerospace, defense and industrial industries and is a portfolio company of Warburg Pincus, a leading global private equity firm.

It producesContinue reading

Aubert et Duval et Airbus engagés dans le projet Mama, aux côtés de l’IRT Saint-Exupéry (FR)

Alors que la fabrication additive monte progressivement en puissance dans l’aéronautique, de nouvelles synergies se profilent entre les procédés classiques de production et ces nouvelles technologies. En Occitanie, plusieurs industriels ouvrent la voie et s’engagent dans l’hybridation des procédés. 

La fabrication additive n’aurait finalement pas vocation à se substituer aux procédés classiques de fabrication, mais plutôt de venir en complémentarité, en jouant la carte de l’hybridation. C’est le message qu’ont voulu faire passer l’IRT Saint-Exupéry et l’agence de développement économique Add’Oc, co-organisateurs d’une journée technologique intitulée “fabrication additive : multi-matériaux et hybridation des procédés”, à laquelle ont participéContinue reading

ATI to sell plants in Indiana, Kentucky for $37M (US)

Allegheny Technologies has agreed to sell two non-core forging facilities for $37 million in cash, according to a release from the company. The facilities, which are located in Portland, Indiana and Lebanon, Kentucky, are part of ATI’s High Performance Materials and Components (HPMC) segment. They use traditional forging methods to produce carbon steel forged products for use in oil and gas, transportation, construction and mining industries. Sales

Voestalpine opens pioneering high-tech steel research facility in Donawitz (US)

22 May 2019  – Light yet tough, ideal for processing and also recyclable—steel is a material with a future. Ongoing steel development provides the basis for new concepts in mobility, energy, and infrastructure. At its unique pilot facility in Leoben-Donawitz, Austria, voestalpine is now conducting research into the production of new high-performance steels which are subsequently processed into special rails, quality rod wire, and extremely high-resistant OCTG by the Group’s companies in Styria. Over EUR 18 million has been invested in the “TechnikumContinue reading

Pentagon eyes rare-earth supplies in Africa in push away from China (US)

The US Department of Defense has held talks with Malawi’s Mkango Resources Ltd and other rare-earth miners across the globe about their supplies of strategic minerals, part of a plan to find diversified reserves outside of China, a department official said on Wednesday. The push comes as China threatens to curb exports to the United States of rare earths, a group of 17 minerals used in a plethora of military equipment and high-tech consumer electronics.  

Although China contains only a third of the world’s rare-earth reserves, it accounts for 80% of US imports of minerals because it controls nearly all of the facilities to process the material, according to US Geological Survey data. “We are looking for any source of supply outside China. We want diversity. We don’t want a single-source producer,” Jason Nie, a materials engineer with the Pentagon’s Defense Logistics Agency, said on the sidelines of the Argus US Specialty Metals conference in Chicago. The DLA, whichContinue reading

The US Next Tank Could Be Protected by ‘Steel Foam’ (US)

Researchers have discovered that composite metal foam offers greater protection than traditional armor steel plate at a third of the weight. The discovery has broad implications for armored vehicles, and could result in stronger, lighter vehicles better able to protect occupants from the impact of kinetic weapons, explosive shockwaves, and fires.Scientists at North Carolina State University and the US Army’s Aviation Applied Technology Directorate have invented what they call Composite Metal Foam (CMF). “Metal foam” is exactly what you think it is—metal with sponge-like holes in it. This not only makes CMF lighter than normal metal, but it also makes CMF spongy, allowing it to give slightly under impact, soaking up some of the energy of a collision.

Researchers have demonstrated that vehicle armor using composite metal foam (CMF) can stop ball and armor-piercing .50 caliber rounds as well as conventional steel armor, even though it weighs less than half as much. The finding means that vehicle designers will be able to develop lighter military vehicles without sacrificing safety, or canContinue reading
