D’ici quelques mois, son siège et son usine tarn-et-garonnaise seront relocalisés sur un nouveau site à quelques kilomètres de là, mais toujours sur la commune de Montauban. Une enveloppe globale de 15 millions d’euros est prévue, dont 11 millionsContinue reading→

ATI-Tsingshan JV under Regulatory Microscope for National Security (US)

Posted on by

US. Specialty Metals Amendment prohibits using non-U.S. melted specialty metals for U.S. Defense applications. “No items for the defense industry are produced by the joint venture due to the commodity-product capability of the Midland plant.”according to Natalie Gillespie, a spokeswoman for ATI.

A group of grass-roots conservative leaders led by Morton Blackwell of the Weyrich Group and Jenny Beth Martin of Tea Party Patriots has just sent a letter to Treasury Secretary Steve Mnuchin demanding an immediate security review of a joint venture between a Pittsburgh specialty steel maker and a Chinese firm that is the world’s largest stainless steel producer. Allegheny Technologies hopes to use the joint venture to import 336,000 metric tons of stainless steel slabs every year from an Indonesian mill owned by China’s Tsingshan Group. The slabs – which would be free of any tariffs – would then be turned into 60-inch-wide steel sheets. About 100 new jobs would be created at an Allegheny plant in Midland, Pennsylvania. The conservative leaders say the joint venture between Allegheny and Tsingshan hasn’t yet been reviewed by the Committee on Foreign Investment in the United States (CFIUS). “China’s history of stealthy intellectual property theft triggers immediate concerns,” they write. “ATI possesses sensitive intellectual property that China could seek to extract and transfer in order to undercut U.S.economic and military advantages.” The conservative leaders point out that in 2014, hackers from the Chinese People’s Liberation Army were charged with cyber intrusions and economic espionage aimed at three U.S. steel producers, including Allegheny. The concern over such espionage is heightened because Allegheny hasContinue reading→

U.S. launches national security probe into titanium sponge imports (US)

Posted on by

WASHINGTON (Reuters) – The U.S. Commerce Department on Monday launched a national security probe into titanium sponge imports, a key input in military aircraft and other equipment like space vehicles, satellites, naval vessels, missiles and munitions. The probe under Section “232” follows an investigation by the Commerce Department in 2017 to review if titanium sponge imports from Japan and Kazakhstan were injuring U.S. producers and was prompted by a petition from U.S.-based Titanium Metals Corp, part of Berkshire Hathaway Inc’s Precision Castparts Corp. In 2017, the U.S. International Trade Commission voted to end its probe into the imports, saying it found no harm. The Commerce Department said the Pentagon supported the national security probe. “Titanium Continue reading→

US Army prints ultra-strong steel parts from powder (US)

Using advanced additive manufacturing techniques, Army scientists work with an Air Force-invented steel alloy to print intricate geometries with ultra-high-strength. This sample, created using a technique called powder bed fusion, is the symbol of the newly formed Army Futures Command. The steel is 50-percent stronger than what is commercially available.

ABERDEEN PROVING GROUND, Md. (Feb. 27, 2019) — Soldiers needing replacement parts may turn to 3-D printers in the future to rapidly deliver reliable and ultra-strong metal parts. Army researchers are looking at new technologies to create steel alloy parts from powder using a laser. At the U.S. Army Combat Capabilities Development Command’s Army Research Laboratory, materials manufacturing scientists say this technology may change everything. “I think it’s going to really revolutionize logistics,” said Dr. Brandon McWilliams, a team lead in the lab’s manufacturing science and technology branch. “Additive manufacturing is going to have a huge impact on sustainment.” While progress remains steady, McWilliams said realizing the dream of quickly printed, reliable 3-D metal parts is still a long way off; however its benefits will be substantial. “You can really reduce your logistics footprint,” he said. “Instead of worrying about carrying a whole Continue reading→

US DOE powers Aluminum and Steelmaking Research through HPC4Manufacturing Program (US)

The HPC4Manufacturing Program announced four federal funding awards for solving key manufacturing challenges in steelmaking and aluminum production through supercomputing. This most recent Call for Proposalshad a special focus — applying the unparalleled HPC capabilities of DOE national labs to steelmaking and aluminum production processes. Under the program, each selected industry partner will have access to the national labs’ HPC machines and expertise to help these industries become more competitive, boost productivity and support American manufacturing jobs.

“Primary metals industries are significant energy users, so opportunities to reduce energy consumption in this area is of great interest to our sponsors,” said HPC4Manufacturing Director Robin Miles of LLNL. “Additionally, this program is helping U.S. steel makers produce the higher strength steels vital to light weighting the next generation of automobiles.

Funded by DOE’s Advanced Manufacturing Office, the HPC4Mfg Program is administered by Lawrence Livermore National Laboratory (LLNL) along withContinue reading→

Titanium pressure vessel for space exploration built successfully using the Wire + Arc Additive Manufacturing process (US)

Posted on by

A team comprising of Thales Alenia Space, Cranfield University and Glenalmond Technologieshave successfully produced a first full-scale prototype of a titanium pressure vessel to be used in future manned missions for space exploration. The piece is approximately 1m in height and 8.5kg in mass. Made of the titanium alloy (Ti-6Al-4V), it has been deposited using the Wire + Arc Additive Manufacturing (WAAM) process, which Cranfield University has pioneered over the last decade. Thanks to being able to go straight from digital drawing to final structure, WAAM has integrated two individual pieces into a single part; eliminating the need for long-lead-time forgings; and substantially reduced the amount of waste material removed by machining. If manufactured traditionally, the component Continue reading→

Aerospace Industry Increasingly Turns to PVD Coatings to Replace Hard Chrome (US)

Posted on by

Thermal barrier coatings protect the engines of military aircraft – like this F100 engine, but are also applied in civil aircraft

The search for a suitable replacement to hard chrome on aerospace components has been a key supply chain priority for aircraft manufacturers. This is because of the documented health risks to workers and the impact on the environment from exposure to hexavalent chromium, a carcinogen that occurs during the chrome plating process and the most toxic form of chromium. As a result, chromium is a highly regulated chemical in major markets worldwide. In the European Union, hexavalent chromium falls under the domain of the EU regulation, REACH Continue reading→

Framatome, champion du zirconium (US)

Posted on by

Chaque année, la France en importe près de 23 000 tonnes d’Afrique du Sud (59% de ses importations totales), et dans une moindre mesure du Mozambique (20%) et du Sénégal (6%)

Extrait du zircon, le zirconium est très prisé par l’industrie nucléaire. “Compte-tenu de sa très bonne transparence aux neutrons, les alliages au zirconium servent surtout de gaines isolantes autour des crayons de combustible des réacteurs dans les centrales”, précise Mathieu Leguérinel. En France, c’est Framatome qui produit le zirconium et le hafnium. Cette filiale d’EDF (anciennement dans le groupe Areva) a développé un savoir-faire dans l’élaboration de ce métal dès les années 1960. Le volume de zirconium qu’elle produit représente 21% des exportations dans le monde. Pour maintenir son rang face aux géants du secteur (tels les américains Westinghouse et ATI), le groupe peut s’appuyer sur sa filière de transformation. Les éponges de zirconium produites à Jarrie (Isère) sont fondues à UgineContinue reading→

A body-centered cubic W-based refractory high entropy alloy with outstanding radiation resistance has been developed. The alloy was grown as thin films showing a bimodal grain size distribution in the nanocrystalline and ultrafine regimes and a unique 4-nm lamella-like structure revealed by atom probe tomography (APT). Transmission electron microscopy (TEM) and x-ray diffraction show certain black spots appearing after thermal annealing at elevated temperatures. TEM and APT analysis correlated the black spots with second-phase particles rich in Cr and Continue reading→
