  • Army researchers are using metallic alloys to lighten the load and enhance the power of Soldier devices used on the battlefield.
  • This research was recently featured on the cover of Advanced Optical Materials.

ADELPHI, Md. (Oct. 2, 2018) — What happens when gold and silver just don’t cut it anymore? You turn to metallic alloys, which are what Army researchers are using to develop new designer materials with a broad range of capabilities for our Soldiers. This is exactly what scientists Dr. David Baker and Dr. Joshua McClure from the U.S. Army Research Laboratory are doing to lighten the load and enhance the power of Soldier devices used on the battlefield. Their research, conducted in collaboration with Prof. Marina Leite and Dr. Chen Gong atContinue reading

US Navy and Lockheed Martin Put Artificial Intelligence Into 3D Printers (US)

The drive to push 3D printing into the field is getting a boost from an unexpected ally — artificial intelligence that can monitor robots and teach them how to do a better job.

One thing about airplanes—especially ones that fly from aircraft carriers, where they’re battered by saltwater and tough deck landings—is that they need lots of spare parts that are not always on hand. Instead of flying in new parts, though, future Navy ships may be able to make new ones to order. Picutre an intelligent, laser-wielding robot that can analyze the damage and 3D-print the needed titanium alloy parts from an onboard supply of metallic dust. This is one glimpse of the future proposed by the Office of Naval Research (ONR), which today announced a two-year, $5.8 million contract to create a new generation of super-smart 3D printers. The printers would not onlyContinue reading

ATI and NLMK Sign Carbon Steel Hot-Rolling Conversion Agreement (US)

Allegheny Technologies announced Thursday it has signed an agreement with NLMK USA to process its steel on ATI’s hot-rolling mill in Harrison. NLMK USA, a subsidiary of a Russian steel company, has production sites in Indiana and Pennsylvania. It produces flat-rolled steel used in manufacturing, and supplies steel coils to the construction, automotive, pipe and tube, and heavy equipment industries in the United States. The agreement for ATI to hot-roll NLMK’s carbon steel slabs into coils runs through December 2019. “Slab shipments to ATI will begin immediately and increase to anticipated production levels in the first quarter of 2019,” ATI said in a release. Neither company is disclosing the dollar value of the agreement, ATI spokeswoman Natalie Gillespie said. ATI’s $1.1 billion steel mill is now Continue reading

The Tungsten’s Bullet That Swims Through Water (US)

Nammo’s penetrators, both for vehicles and other types of armor piercing ammunition, are made out of a super tough tungsten alloy, also known as wolfram. More than two times as heavy as steel, it has the second highest melting point of any element, making it ideal for use in armor piercing ammunition. For some ammunition types, including the 25 mm APEX for the F-35, tungsten is mixed with carbon, creating tungsten carbide. This makes the penetrators harder, but also more brittle, allowing them to fragment once they have penetrated the armor, causing added damage inside the target

The U.S. Navy and Norwegian defense group Nammo have developed a super-cavitating bullet that can travel through water. While traditional ammunition is either stopped or deflected when it hits water, Nammo’s 30 mm Swimmer (APFSDS-T MK 258 Mod 1) swims straight through it. Nammo says the U.S. Army and the U.S. Navy are now adopting the Swimmer for use from many platforms, includingContinue reading

For the past 10 years, the U.S. Air Force has funded research on high-performance materials at the Cornell High Energy Synchrotron Source (CHESS). The partnership has resulted in numerous advances, including a greater understanding of metal fatigue and analysis of the best metals for aircraft. This partnership was extended with $8 million in funding to CHESS as part of the fiscal year 2019 defense Continue reading

Blackstone, Carlyle, Onex, and CPPIB Plan to buy ARCONIC (US)

  • Blackstone, Carlyle Group, Onex Corp., and Canada Pension Plan Investment Board have joined forces in a bid to acquire aluminum products maker Arconic, according to people familiar with the matter.
  • Earlier this month, a Blackstone-led consortium completed the largest leveraged buyout since the crisis, taking over the financial data arm of Thomson Reuters, the parent of Reuters News.
  • Arconic has the potential to rival that deal should the private-equity firms that are seeking to acquire it decide to pay a significant premium. Arconic has a market capitalization of $10.6 billion and total debt of $6.3 billion.

U.S. grants most of Voestalpine’s requests for exemptions to steel tariffs (US)

VIENNA (Reuters) – The United States has granted more than half of the exemptions to its steel import tariffs that Austrian steelmaker Voestalpine and its customers applied for, the company said on Tuesday. Washington in May announced tariffs of 25 percent on steel imports and 10 percent on aluminum from the European Union, Canada and Mexico. Of the 4,300 product exemptions that the company and its customers applied for, 2,640 haveContinue reading
