Starship : Elon Musk explique pourquoi il a choisi l’acier inoxydable pour sa nouvelle fusée (FR)

Coût, facilité d’emploi, faible perte et propriétés mécaniques : Elon Musk ne voit que des avantages dans l’acier inoxydable.

C’est le 11 janvier qu’a été présentée la nouvelle fusée de SpaceX, celle qui succédera à terme aux deux lanceurs actuels de l’entreprise, le Falcon 9 et le Falcon Heavy. Son look résolument rétro a immédiatement fait penser à la fusée dont se sert Tintin pour se rendre sur la Lune. Mais plus que son aspect général, ce sont les choix d’ingénierie de SpaceX qui interpellent. L’entreprise américaine a en effet renoncé à une conception en fibre de carbone. À la place, elle utilise désormais un alliage spécial à base d’acier inoxydable. Celui-ci est utilisé aussi bien pour la fusée Starship (nom donné au véhicule spatial ainsi qu’à l’étage supérieur) que pour le booster Super Heavy (qui constitue le premier étage de l’engin). Il peut sembler bien étrange de voir une entreprise comme SpaceX, pourtant en pointe dansContinue reading

Ce que promet le contrat de filière mines et métallurgie (FR)

Des standards de référence pour la mine responsable, la digitalisation des mines et carrières et une filière de recyclage des batteries au lithium, ce sont les trois promesses principales du contrat de filière signé le 18 janvier à Bercy par la secrétaire d’Etat Agnès Pannier-Runacher et la présidente du Comité stratégique de la filière mines et métallurgie Christel Bories.

Après un an et demi de travail, le contrat de la filière Mines et métallurgie, élaboré au sein du Comité stratégique de filière, a été signé le vendredi 18 janvier dans une salle de réunion du ministère de l’Economie et des finances. Premières signataires, deux femmes : la PDG d’Eramet Christel Bories, qui préside le CSF, et la secrétaire d’Etat auprès du ministre de l’Economie et des Finances Agnès Pannier-Runacher. Souhaitons que ce soit un signal faible d’un monde qui change, dans une filière qui reste beaucoup plus masculine que ses instances de représentation.

“L’objectif de ce contrat de filière est de réunir les forces des entreprises, des organisations syndicales et les services de l’Etat pour construire des projets très concrets autour des compétences qui manquent à la filière, de la transformation et de l’innovation notamment en matière numérique, et de la réduction de l’empreinte écologique pour que l’ensemble de ces entreprises, qui se situent très en amont de beaucoup d’autres sites industriels, se situent aux meilleurs standards du marché, qui est très concurrentiel”, a déclaré Agnès Pannier-Runacher après la signature.Continue reading

voestalpine pins lowered profit forecast on Bartow plant (US)

“An ongoing shortage of skilled workers in the region has had an impact on the fact that we have not been able to find and maintain enough qualified personnel to process these orders in time,” a voestalpine AG representative told The Daily Tribune News.

On Wednesday, voestalpine AG gave investors some discomforting news — not only did the Linz, Austria-based manufacturer miss its nine-month earning forecast by 187 million euros (equivalent to roughly $213 million), the international steel company also announced it was lowering its full-year profit forecast from roughly 1 billion euros ($1.13 billion) to about $750 million euros ($854.1 million.). Such marks the second time voestalpine has lowered its profit forecast in the current fiscal year. By Thursday, voestalpine shares were down by as much as 8 percent — a substantial decrease for a company that already saw its shares lose almost half their value over the lastContinue reading

3D printing eliminates undesirable trait in conventional superalloys (US)

Allison Beese, assistant professor of materials sciences and engineering at Penn State, sits in front of the control panel during her experimentation with 3D Inconel 635 at Oak Ridge National Laboratories.

UNIVERSITY PARK, Pa. — An undesirable trait found in traditionally processed superalloys does not exist in a 3D-printed, nickel-based superalloy, according to a team of materials scientists who think this could lead to new manufacturing techniques that allow for alloys with tailored properties.  The trait, called dynamic strain aging (DSA), occurs in metals at high temperatures subjected to stress. In conventionally processed materials, if DSA is present, the strength of the material fluctuates with applied deformation, resulting inContinue reading

Why Military, Aerospace Industries Rely Heavily on Titanium (US)

Commercial manufacturers have used titanium since 1947 when just two tons of the versatile metal were produced each year. Making use of titanium’s superior strength-to-weight ratio along with its robust anticorrosive properties, governmental and military interests drove titanium production to 2,000,000 pounds annually by 1953. Today, the aerospace industry accounts for 73% of titanium used in the U.S., but military manufacturers are also increasingly adopting titanium for their own advanced hardware applications. Military and aerospaceContinue reading

A $48 million submarine will dive to the deepest point in the ocean, where only 3 people have been before (US)

Its 3.5-inch thick titanium pressure hull was built using advanced forging techniques, and Triton tested the vessel in Russia with conditions equivalent to 43,300 feet, or 20% greater than the ocean’s deepest point

  • Only three people have previously been to the Challenger Deep, the deepest point of the ocean.
  • A new submersible from Triton Submarines will make it possible for many more people to reach 36,000-foot depths.
  • The Triton 36,000/2 Hadal Exploration System has a 3.5-inch thick titanium pressure hull and three viewports for pilots to see the water around them.

Twelve people have walked on the moon, but only three have ventured to the Mariana Trench’s Challenger Deep, the deepest point of the ocean. But Florida-based Triton Submarines is trying to expand access to these depths with its new $48.2 million submarine system. TheContinue reading

Former U.S Navy SEAL officer and Blackwater founder launches fund to invest in electric car battery metals (US)

Erik Prince, the founder of controversial U.S. private security firm Blackwater and an informal campaign adviser to President Donald Trump, is looking to raise as much as $500m to invest in metals used in the batteries that power electric cars.

Blackwater founder Erik Prince aims to raise as much as $500 million to invest in metals needed for making the batteries that power electric vehicles (EVs), the Financial Times reports. Prince, who besides starting the controversial private security company is known for have been an informal campaign adviser to US President Donald Trump, said the fund will bring unexplored deposits into production and then sell them to large miners after four to five years. The fund will focus mainly on cobalt, copper and lithium assets located mainly inContinue reading

China’s Cheap Steelmaking Machines Pose Safety Concerns in Southeast Asia (US)

MANILA—China banned induction furnaces last year in a crackdown on polluting producers of low-quality steel, but the equipment has made its way to parts of Southeast Asia, putting pressure on domestic steelmakers and fueling safety and environmental concerns. The Philippines and Indonesia have seen an influx of these furnaces since China prohibited their use for steelmaking in June 2017, eliminating 154 million tons of capacity—or just over the combined output of the United States and Germany. The two Southeast Asian nations—big steel importers with fast-growing economies—are ideal markets for these induction furnaces, or IFs, that produce cheaper steel. But some Continue reading
