Decoupling stress and corrosion to predict metal failure (US)

An Arizona State University research team has released new insights about intergranular stress-corrosion cracking (SCC), an environmental cause of premature failure in engineered structures, including bridges, aircraft and nuclear power generating plants. The research, Decoupling the role of stress and corrosion in the intergranular cracking of noble alloys, released today in Nature Materials, addresses the assumption that intergranular SCC is the result of the simultaneous presence of a tensile stress and corrosion, and demonstrates that the roles of stress and corrosion can be decoupled, or can act independently. “The finding is the culmination of about 30 years’ work on this kind of stress corrosion problem,” said lead researcher Karl Sieradzki, a professor of materials science andContinue reading

Russia’s VSMPO-Avisma (VSMO.MM), the world’s largest titanium producer, and U.S. planemaker Boeing (BA.N) have launched a new manufacturing unit in Russia’s Urals region of Sverdlovsk, a local governor said on social media on Wednesday. The joint venture (JV) will receive 5.5 billion roubles ($82.3 million) of investment, Evgeny Kuyvashev said.   Russia’s VSMPO-Avisma (VSMO.MM), the world’s largest titanium producer, and U.S. planemaker Boeing (BA.N) have launched a new manufacturing unit in Russia’s Urals region of Sverdlovsk, a local governor said Continue reading

Arconic considers selling itself after bid interest (US)

Private equity firms including KKR, Blackstone and Apollo are exploring a deal

Arconic is considering selling itself after the aluminium products company was approached by several private equity players interested in buying out the Alcoa-spin-off, people familiar with the matter said. A consortium of Blackstone and Carlyle and another group of private equity groups including of KKR and Onex have expressed their interest in acquiring Arconic, those briefed on the approach said. They added that Apollo, another US private equity group, is also exploring a deal. The talks are at an early stage and come weeks after the US company said it was planning to sell the building products unit that provided the external cladding applied to London’s doomed Grenfell Tower. Arconic was initially opposed to selling itself but a person close to the company told the FT last month that it would be open to do Continue 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

Constellium CEO Says Company Still Open to ‘Serious’ Suitors (US)

  • ‘We’re for sale every day as a listed company,’ Germain says
  •  Constellium was seen weighing options for takeover last year

Constellium NV, which was said to have drawn takeover interest last year, hasn’t closed the door to prospective suitors, Chief Executive Officer Jean-Marc Germain said. “We’re for sale every day as a listed company, so we’ll study any offer that is serious,” Germain said in a telephone interview Monday. “If somebody comes in, it’s got to be something that makes a real difference for our shareholders vis-a-vis executing our plan.” Last year, the Dutch maker of aluminum products used in automobiles, aerospace and packaging which runs plants in the U.S. was said to be weighing options after drawing takeover interest. At the time, Credit Suisse Group AG analysts said the company could be worth as much as $18 a share in a takeover. Shares climbed 3.3 percent to $11.875 at 1:32 p.m. in New York. Rising demand forContinue reading

New UK machining facility opens at Sheffield Forgemasters (US)

Sheffield Forgemasters International Ltd (SFIL) has opened a new machining facility, the only one of its kind in the UK.

SFIL claims it has installed the UK’s largest 5-axis vertical turning lathe (VTL) manufactured by Spanish company, Bost, as part of a £6 million upgrade to its machining facilities and to dramatically improve its capacity and throughput for complex machining requirements. Commissioning of the VTL was attended by delegates from Sheffield City Region Local Enterprise Partnership, which helped to fund the VTL installation, alongside seniorContinue reading

Ellwood Group Diversifies with $60M Aluminum Plant (US)

HUBBARD TOWNSHIP, Ohio — The $60 million aluminum slab and billet plant that Ellwood Group Inc. plans to build here to house its new Ellwood Aluminum division has been three years in the making, officials say, with the green light coming this spring from the parent company’s board of directors. The 70,000-square-foot plant will be built at the site of Ellwood Engineered Castings, 7158 Hubbard Masury Road. That plant employs about 100, says Patrick F. Callihan, president of Ellwood Engineered Castings, who is overseeing the expansion. Once operating at full capacity, the new aluminum plant is expected to employ 34. “We’ve signed on with an engineering firm inContinue reading

Outstanding Metallurgist Richard Sisson Named a Fellow of Two Materials Science and Engineering Professional Societies (US)

Sisson is the principal investigator for a multi-million-dollar, multi-institution project funded by the U.S. Army aimed at developing new metallurgical methods and new lightweight alloys for military vehicles and systems.

His internationally renowned research is honored by the International Federation for Heat Treatment and Surface Engineering and the American Ceramic Society

August 29, 2018 –  Richard Sisson Jr., George F. Fuller Professor of Mechanical Engineering and director of the Manufacturing and Materials Science and Engineering programs at Worcester Polytechnic Institute (WPI), has been named a fellow of two materials science professional societies, the International Federation for Heat Treatment and Surface Engineering (IFHTSE), and the American Ceramic Society (ACerS). Sisson, who directs the Center for Heat Treating Excellence, part of WPI’s Metal Processing Institute, received the IFHTSE fellowship at the 4th International Conference on HTSE in Automotive Applications in Spartanburg, S.C., in June, where he also delivered one of the conference’s three keynote addresses. His presentation was titled “Challenges and Opportunities for the Heat Treating Community: Threats, Risks, and Benefits.”

Keep cool: Researchers develop magnetic cooling cycle (US)

A novel technology could provide a solution for cooling processes: refrigeration using magnetic materials in magnetic fields. Researchers have developed the idea of a cooling cycle based on the ‘magnetic memory’ of special alloys.- On photo, The Dresden High Magnetic Field Laboratory of te HZDR, where the new magnetic cooling system was developed

Besides superfluous features like touchscreens and internal cameras, basic refrigerator technology hasn’t changed much in decades. They still chill your milk by way of chemical refrigerants and compressors, and are notorious drains on your electricity bill. Now researchers in Europe have shown promising early results with an experimental cooling system that uses magnetic fields and shape-shifting memory alloys. Magnetic cooling systems work by exploiting the magnetocaloric effect – which basically means that certain materials will change temperature whenContinue reading
