The Pentagon has identified cobalt and copper as “strategic and critical minerals” for the production of military planes, missile guidance systems, and other hardware. According to the U.S. Department of Defense, cobalt is a critical material because it used as a superalloy in military and commercial jet engines, and it is very difficult to substitute because of its very high heat resistance. As of 2014, 16 percent of the world’s cobalt was used in superalloys, five percent was used in magnets, and 42 percent was used in batteries, all of which are essential in military hardware as well as in hybrid and electric cars, commercial planes, and consumer electronics.

La durabilité des composants en alliages métalliques – aciers, aluminiums, bases nickel – dans le domaine des industries pétrolières et gazières, de la chimie, de la production d’énergie, peut être limitée par des facteurs :
- Internes: ségrégations d’éléments d’alliage lors de la solidification, des traitements thermiques et de la mise en forme pendant la fabrication, ou suite au vieillissement thermique
- Externes: fragilisation par l’hydrogène, corrosion sous contraintes, fatigue corrosion
Le Cercle d’Etudes des Métaux organise avec la SF2M à l’Ecole des Mines de Saint-Etienne une journée sur cette thématique. Les trois thèmes suivants y seront abordés :
- ségrégations et micro-ségrégations d’éléments d’alliage et résiduels – carbone, phosphore, soufre, intermétalliques…- dans les tôles, pièces de forge et de fonderie,
- diminution de l’endommagement en service, par des élaborations, traitements thermiques, thermomécaniques et de surface appropriés,
- amélioration de la résistance à la fragilisation par l’hydrogène, à la fissuration par corrosion sous contraintes ou par fatigue corrosion, du fait des améliorations des connaissances et moyens d’investigation et, de ce fait, des progrès survenus dans les processus de fabrication.

Swedish steelmaker Ovako is claiming that it’s new family of hybrid steels represents one of the most significant developments in steel metallurgy ‘for decades’ and offers the properties of tool steel, maraging steel and stainless steel combined with the production economy of engineering steel.
Launching it’s new range of products at the Euromat 2017 exhibition in Thessaloniki, Greece, Ovako claims that it’s new steel product opens up new possibilities to use steel components in very demanding applications.
“We set ourselves the goal of developing a steel that would address the segregation issues while also being suitable for high volume production by the cost-effective electric arc furnace route. It became clear that the key to success was to adopt a hybrid approach in which the steel would utilise two different, but complementary hardening mechanisms – secondary hardening and intermetallic precipitation hardening. The result is the hybrid steel family that will develop over time to cover a range of grades for various applications,”
Patrik Ölund, head of Ovako Group R&D
According to Ovako, hybrid steel offers exceptional performance, especially at elevated temperatures, and can be produced in high volume to meet customer demand at an attractive price. The company claims that the properties of Read more
