La corrosion d’un acier en milieu argileux (FR)

Une équipe de l’Iramis a analysé la corrosion à long terme d’un acier en milieu argileux dans les conditions du stockage géologique de déchets nucléaires : une couche d’oxyde de fer d’épaisseur sub-micronique apparaissant au contact de l’acier fixe la cinétique de l’altération. Un résultat qui enrichit les modèles de corrosion du CEA et de l’Andra !

Le conditionnement de déchets nucléaires à haute activité et vie longue devra comporter plusieurs barrières pour isoler les radionucléides de l’environnement pendant la durée requise par le stockage. L’une de ces barrières est un sur-conteneur en acier qui se corrodera extrêmement lentement, pendant plusieurs milliers d’années. Alors que des expériences de terrain se poursuivent à l’Andra en Read more

Dr. Othmane Benafan, NASA Materials Engineer Develops Shape Memory Alloys for Aerospace Components (US)

Dr. Othmane Benafan, co-principle investigator for the Spanwise Adaptive Wing Project, inspects a model of the shape memory alloy actuator and the outer wing section from an F/A-18 research plane.

While aeronautics researchers across the globe continue to develop technologies that will make air travel more efficient, more sustainable and safer, there is a group of NASA researchers who are altering the long-held view that wings have to stick straight out from an aircraft and stay that way. Through NASA’s Convergent Aeronautics Solutions (CAS) Project, a team of engineers working within its Spanwise Adaptive Wing (SAW) project is investigating the feasibility of bending or shaping portions of an aircraft’s wings in-flight, potentially increasing performance and efficiency by reducing weight and drag. The ability to fold wings isn’t new. Since the dawn of ship-based aviation, U.S. Navy aircraft have been required to fold their wings for space conservation. Currently, this type of wing folding, orRead more

Russian Researchers Develop New Ultra-Light Magnesium Aerospace Parts (US)

Materials scientists from NUST MISIS have come up with an effective and economical way to produce a durable and corrosion-resistant magnesium alloy for use in the automotive and aerospace industries.

A new type of flux (a purifying agent used in metallurgy) developed by the researchers allows for the creation of a unique alloy with improved stress-strain characteristics and corrosion resistance properties. The use of magnesium parts contributes to an aircraft or vehicle`s weight reduction. Currently, commercial testing of the technology is being conducted on domestic aircraft manufacturing enterprises —Kamensk-Uralsky Foundry, UEC Saturn, and the Kazan Engine Building Industrial Group, among others.

Magnesium, a very lightweight metal, has a density significantly below that of titanium and aluminum (1.73 grams per cubic cm compared with 4.5 and 2.7 grams, respectively).For aviation and space, where there is a struggle forRead more

New Research Finds Cause of Alloy Weakness (US)

For years, materials scientists have been perplexed by the question of why alloys don’t meet their full potential strength. A deep look at atomic patterns finds the answer.

Sometimes calculations don’t match reality. That’s the problem that has faced materials scientists for years when trying to determine the strength of alloys. There has been a disconnect between the theoretical strength of alloys and how strong they actually are. So, what has been missing ? New research has found the answer to this problem with a study done as a collaboration between researchers at Binghamton University, the University of Pittsburg, the University of Michigan and Brookhaven National Laboratory. The work was also supported by the U.S. Department of Energy’s Office of Science. Researchers used advanced technology to look at alloys on an atomic level in order toRead more
