ATI and NLMK Sign Carbon Steel Hot-Rolling Conversion Agreement (US)

Allegheny Technologies announced Thursday it has signed an agreement with NLMK USA to process its steel on ATI’s hot-rolling mill in Harrison. NLMK USA, a subsidiary of a Russian steel company, has production sites in Indiana and Pennsylvania. It produces flat-rolled steel used in manufacturing, and supplies steel coils to the construction, automotive, pipe and tube, and heavy equipment industries in the United States. The agreement for ATI to hot-roll NLMK’s carbon steel slabs into coils runs through December 2019. “Slab shipments to ATI will begin immediately and increase to anticipated production levels in the first quarter of 2019,” ATI said in a release. Neither company is disclosing the dollar value of the agreement, ATI spokeswoman Natalie Gillespie said. ATI’s $1.1 billion steel mill is now Continue reading

The Tungsten’s Bullet That Swims Through Water (US)

Nammo’s penetrators, both for vehicles and other types of armor piercing ammunition, are made out of a super tough tungsten alloy, also known as wolfram. More than two times as heavy as steel, it has the second highest melting point of any element, making it ideal for use in armor piercing ammunition. For some ammunition types, including the 25 mm APEX for the F-35, tungsten is mixed with carbon, creating tungsten carbide. This makes the penetrators harder, but also more brittle, allowing them to fragment once they have penetrated the armor, causing added damage inside the target

The U.S. Navy and Norwegian defense group Nammo have developed a super-cavitating bullet that can travel through water. While traditional ammunition is either stopped or deflected when it hits water, Nammo’s 30 mm Swimmer (APFSDS-T MK 258 Mod 1) swims straight through it. Nammo says the U.S. Army and the U.S. Navy are now adopting the Swimmer for use from many platforms, includingContinue reading

U.S. Air Force Funds Research on High-Performance Materials (US)

For the past 10 years, the U.S. Air Force has funded research on high-performance materials at the Cornell High Energy Synchrotron Source (CHESS). The partnership has resulted in numerous advances, including a greater understanding of metal fatigue and analysis of the best metals for aircraft. This partnership was extended with $8 million in funding to CHESS as part of the fiscal year 2019 defense Continue reading

Blackstone, Carlyle, Onex, and CPPIB Plan to buy ARCONIC (US)

  • Blackstone, Carlyle Group, Onex Corp., and Canada Pension Plan Investment Board have joined forces in a bid to acquire aluminum products maker Arconic, according to people familiar with the matter.
  • Earlier this month, a Blackstone-led consortium completed the largest leveraged buyout since the crisis, taking over the financial data arm of Thomson Reuters, the parent of Reuters News.
  • Arconic has the potential to rival that deal should the private-equity firms that are seeking to acquire it decide to pay a significant premium. Arconic has a market capitalization of $10.6 billion and total debt of $6.3 billion.

Eramet: a new brand identity for a new leap forward (US)

“This new logo symbolizes the Group’s current and future transformation. Its graphic design represents the dynamics we want to give to Eramet. And our new symbol, the leap, represents the energy, the projection into the future, making Eramet a moving, modern and ambitious brand. This is the new Eramet”.

Christel Bories, Eramet CEO:

Energy transition, optimization and preservation of resources, sustainable development: mining and metallurgical activities are at the heart of the challenges of the planet. In pursuit of those stakes, Eramet takes a new strategical leap and aspires to become the leader of the metals for energy transition. Launched a year ago, the managerial transformation program intends to create Continue reading

U.S. grants most of Voestalpine’s requests for exemptions to steel tariffs (US)

VIENNA (Reuters) – The United States has granted more than half of the exemptions to its steel import tariffs that Austrian steelmaker Voestalpine and its customers applied for, the company said on Tuesday. Washington in May announced tariffs of 25 percent on steel imports and 10 percent on aluminum from the European Union, Canada and Mexico. Of the 4,300 product exemptions that the company and its customers applied for, 2,640 haveContinue reading

Carpenter, Arconic, P&W, and Siemens awarded funding for advanced materials research programs (US)

Carpenter Technology Corporation will partner with LLNL to develop a predictive model of APB energy for superalloys to improve the “virtual synthesis” process in industry in a project titled “Development of a Predictive Model of Antiphase Boundary Energy for L12 Strengthened Superalloys”.
Arconic Inc. will partner with LLNL and ORNL to develop advanced understanding of the non-equilibrium metallic phases established during metal additive manufacturing (AM) processes in a project titled “Multiscale Modeling of Microstructure Evolution During Rapid Solidification for Continue reading

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
