3D printing eliminates undesirable trait in conventional superalloys (US)

Allison Beese, assistant professor of materials sciences and engineering at Penn State, sits in front of the control panel during her experimentation with 3D Inconel 635 at Oak Ridge National Laboratories.

UNIVERSITY PARK, Pa. — An undesirable trait found in traditionally processed superalloys does not exist in a 3D-printed, nickel-based superalloy, according to a team of materials scientists who think this could lead to new manufacturing techniques that allow for alloys with tailored properties.  The trait, called dynamic strain aging (DSA), occurs in metals at high temperatures subjected to stress. In conventionally processed materials, if DSA is present, the strength of the material fluctuates with applied deformation, resulting inContinue reading

Why Military, Aerospace Industries Rely Heavily on Titanium (US)

Commercial manufacturers have used titanium since 1947 when just two tons of the versatile metal were produced each year. Making use of titanium’s superior strength-to-weight ratio along with its robust anticorrosive properties, governmental and military interests drove titanium production to 2,000,000 pounds annually by 1953. Today, the aerospace industry accounts for 73% of titanium used in the U.S., but military manufacturers are also increasingly adopting titanium for their own advanced hardware applications. Military and aerospaceContinue reading

A $48 million submarine will dive to the deepest point in the ocean, where only 3 people have been before (US)

Its 3.5-inch thick titanium pressure hull was built using advanced forging techniques, and Triton tested the vessel in Russia with conditions equivalent to 43,300 feet, or 20% greater than the ocean’s deepest point

  • Only three people have previously been to the Challenger Deep, the deepest point of the ocean.
  • A new submersible from Triton Submarines will make it possible for many more people to reach 36,000-foot depths.
  • The Triton 36,000/2 Hadal Exploration System has a 3.5-inch thick titanium pressure hull and three viewports for pilots to see the water around them.

Twelve people have walked on the moon, but only three have ventured to the Mariana Trench’s Challenger Deep, the deepest point of the ocean. But Florida-based Triton Submarines is trying to expand access to these depths with its new $48.2 million submarine system. TheContinue reading

Former U.S Navy SEAL officer and Blackwater founder launches fund to invest in electric car battery metals (US)

Erik Prince, the founder of controversial U.S. private security firm Blackwater and an informal campaign adviser to President Donald Trump, is looking to raise as much as $500m to invest in metals used in the batteries that power electric cars.

Blackwater founder Erik Prince aims to raise as much as $500 million to invest in metals needed for making the batteries that power electric vehicles (EVs), the Financial Times reports. Prince, who besides starting the controversial private security company is known for have been an informal campaign adviser to US President Donald Trump, said the fund will bring unexplored deposits into production and then sell them to large miners after four to five years. The fund will focus mainly on cobalt, copper and lithium assets located mainly inContinue reading

China’s Cheap Steelmaking Machines Pose Safety Concerns in Southeast Asia (US)

MANILA—China banned induction furnaces last year in a crackdown on polluting producers of low-quality steel, but the equipment has made its way to parts of Southeast Asia, putting pressure on domestic steelmakers and fueling safety and environmental concerns. The Philippines and Indonesia have seen an influx of these furnaces since China prohibited their use for steelmaking in June 2017, eliminating 154 million tons of capacity—or just over the combined output of the United States and Germany. The two Southeast Asian nations—big steel importers with fast-growing economies—are ideal markets for these induction furnaces, or IFs, that produce cheaper steel. But some Continue reading

SINTERmat: La métallurgie de l’avenir débarque à Montbard (FR)

La start-up SINTERmat, spécialiste de la métallurgie des poudres, a choisi Montbard comme lieu d’implantation.

De la fierté. Tel est le sentiment qu’avoue Laurence Porte, la maire de Montbard, lorsqu’elle évoque l’installation de l’entreprise SINTERmat à Montbard. Car c’est un enfant du pays qui revient en ses terres natales pour lancer son activité. Originaire de Venarey-Les Laumes, Foad Naimi est à l’origine de la création de SINTERmat. L’entreprise, spécialisée dans la métallurgie des poudres, emploiera sept personnes.

Artificial intelligence meets materials science (US)

A Texas A&M University College of Engineering research team is harnessing the power of machine learning, data science and the domain knowledge of experts to autonomously discover new materials. The team developed and demonstrated an autonomous and efficient framework capable of optimally exploring a materials design space (the materials design space is an abstraction of the concrete world. It is the space of all the possible materials under study, characterized by fundamental material features). An autonomous system — or artificial intelligence (AI) agent — is defined as any system capable of building an internal representation, or model, of the problem of interest, and that then uses the model to make decisions and take actions independent of human involvement. The authors of this interdisciplinary Continue reading

Posco hires ex-Daelim CEO for future growth (US)

Steel giant Posco has hired former the CEO of Daelim Industrial to seek the company’s future growth, it said Thursday in a statement. Oh Gyu-seok, former president of the local builder, will take charge of the newly established future growth division assigned to pave the way for the 50-year-old steelmaker struggling to find alternatives amid declining market demand for metal. Oh is the first outsider to take the Continue reading

Après un parcours complet au sein du groupe ArcelorMittal depuis 1989, Bruno Ribo vient de prendre ses fonctions à la tête d’ArcelorMittal Méditerranée à Fos. Ingénieur de formation, il quitte la direction de l’usine de Galati en Roumanie, couplée à celle de Skopje (Macédoine) dont le groupe a dû se séparer, à la demande de la Commission européenne, pour pouvoir intégrer le site d’Ilva, en Italie.

Où en est-on de l’intégration d’Ilva ? Que peut en attendre Fos ?
Bruno Ribo : 
La cession n’est pas encore finalisée, elle doit se faire dans le courant du premier trimestre et doit être approuvée par la Commission européenne. Le site d’Ilva a un aval plus complet que Fos. ArcelorMittal n’était pas présent de façon significative jusque-là en Italie exceptée à travers son usine de Piombino spécialisée dans le finishing. Fos a une place importante dans la production de “produitsContinue reading
