EcoTitanium: quand le titane s’allie à l’économie circulaire (FR)

Posted on by

Première usine de recyclage de titane aéronautique en Europe, EcoTitanium s’affiche comme un nouvel acteur dans l’approvisionnement de l’industrie aéronautique. Située dans le Puy-de-Dôme, l’entreprise recycle. Et recrute.

Située à Saint-Georges-de-Mons (Auvergne), EcoTitanium est la première usine de recyclage de titane aéronautique en Europe capable de produire des alliages à partir de chutes massives et de copeaux de titane collectés chez les grands constructeurs aéronautiques et leurs sous-traitants.

Des technologies de pointe

Pour cela, la joint-venture d’Aubert & Duval (groupe Eramet) et du kazakh UKTMP International avec l’État français dans le cadre du Programme des Investissements d’Avenir et le Crédit Agricole Centre France, a investi près de 48

The award is selected from young researchers all over the world who are early in their career – preferablyContinue reading→

U.S-Hired Firm Audits Russia’s Rusal For Compliance With Sanctions Deal (US)

Posted on by

MOSCOW (Reuters) – A firm hired by the U.S. Treasury Department is auditing Russian aluminum giant Rusal to check whether it is complying with the terms of a deal under which Washington agreed to lift sanctions on the company, Rusal said. The audit is the first glimpse of how Treasury is policing whether Rusal and its parent company En+ are adhering to the deal – in particular the stipulation that Russian oligarch Oleg Deripaska’s control over the business be severed. A source familiar with the situation said the audit included checks on the telephone and email records of a small circle of Rusal senior executives and board members to establish whether they remained in contact Continue reading→

Universal Alloys Corporation To Build in Vietnam The First Aerospace Components Factory (US)

Posted on by

The construction of Vietnam’s first aerospace component factory in Da Nang city begins on March 29. 

The Universal Alloys Corporation ASIA PTE., LTD (UAC) and the People’s Committee of the central city of Da Nang on March 29 started the construction of an aerospace component factory in the city. The Sunshine factory, the first of its kind in Vietnam, has a registered investment of 170 million USD and aims to produce and install aerospace components from aluminum alloys and composite in service of the industry. It will turn out about 4,000 out of the 5 million aircraft components, all for export. The factory is scheduled to achieve an export value of 25 million USD inContinue reading→

HY-100 the oustanding steel of the U.S. Navy’s Seawolf-Class Submarine (US)

Posted on by

To combat the threat of the Soviet’s Akula class, the U.S. Navy responded with the Seawolf class of nuclear attack submarines. The Seawolf submarines were designed with HY-100 steel alloy hulls  two inches thick , the better to withstand the pressures of deep diving. HY-100 steel is roughly  20 percent stronger  than the HY-80 used in the Los Angeles class. As a result, the submarines are capable of diving to depths of up to two thousand feet, and crush depth estimates run from 2,400 to 3,000 feet.

he extreme quietness of the Seawolf class gave the Navy the idea of modifying the last submarine, USS Jimmy Carter, to support clandestine operations. An extra one hundred feet was added to the hull, a section known as the  Multi-Mission Platform  (MMP). The MMP gives Carter the ability to send and recover Remotely Operated Vehicles/Unmanned Underwater Vehicles and SEALs and diving teams while submerged. It includes berthing for up to fifty SEALs or other attached personnel. Carter also features auxiliary maneuvering devices fore and aft for precise maneuvering in situations such as undersea cable tapping and other acts of espionage.Continue reading→

US Navy invents zinc-free anode enhanced by ‘very small addition of tin (US)

Posted on by

A U.S. Navy research team has discovered an alloy for making better, cheaper underwater anodes with the potential for shifting the global business of maintaining ships and piers. A patent application was published by the federal government on Thursday for the new aluminum anode alloy containing a “very small addition of tin.” It was invented by Craig Matzdorf and Alan Grieve of the Naval Air Warfare Center’s Aircraft Division in Maryland. Sacrificial anodes are attached to marine vessels and structures to protect them from corrosion caused by the flow of electrons between metal surfaces like iron, steel, and aluminum. When submerged in seawater, these metals form a battery. Many anodes are made of alloys consisting mostly of zinc, a metal that can easily absorb the electrons Continue reading→

Carbon-fiber composite materials have been the darling of the aerospace industry in recent years. But, metal still plays a critical role in commercial and military aircraft, especially for applications that involve high temperatures or high stresses, such as engines and landing gear. Engineers at the Air Force Research Laboratory (AFRL) are exploring new metals and new metal processing techniques for use in hotter, faster and more efficient aircraft and spacecraft being developed for future combat missions. “Until you can make a jet engine out of anything else, metals Continue reading→

US Department of Defense, grants research for detecting structural damage in high-strength ship-building materials (US)

Posted on by

Haiying Huang, a professor of mechanical and aerospace engineering at The University of Texas at Arlington, has earned a pair of grants worth nearly $900,000 to monitor structural health and detect when and where damage happens. Using a $599,928 grant from the Department of Defense, Huang will attempt to design ultrasound transducers, devices that convert mechanical vibrations to electrical signals or vice versa, that can be glued to ships’ hulls to detect and monitor material degradation that causes corrosions on high-strength ship-building materials. These material degradations are microscale in size and usually cover the entire surface of the hull. If they are not treated, they can cause the alloys to break down and impact the ship’s seaworthiness. Huang’s research will focus on degradations that are early in their development, when they are so small that they are undetectable by Continue reading→

Ph.D. candidate Jimmy Toton from RMIT University in Melbourne, Australia, has won the 2019 Young Defence Innovator Award and $15,000 prize at the Avalon International Airshow for the research, which was conducted with Defence Materials Technology Centre (DMTC) and industry partner Sutton Tools. Because the metals used in Defence and aerospace are so strong, making high quality tools to cut them is a major, and expensive, challenge. This collaborative project conducted at RMIT’s Advanced Manufacturing Precinct is the first convincing demonstration of 3-D printed steel tools that can cut titanium alloys as well as, or in some cases better than, conventional steel tools. “Now that we’ve shown what’s possible, the full potential of 3-D printing can start being applied to this Continue reading→
