World’s Largest 1.8 M Titanium 3D Print Drone for Defense Industry (US)

Posted on by


Australian advanced manufacturing company Titomic has delivered the largest titanium 3D printed drone or unmanned aerial vehicle (UAV) ever made, measuring more than 1.8 metres in diameter.

The UAV was manufactured at Titomic’s R&D Bureau in Melbourne, home of the world’s largest and fastest metal 3D printer. Reports from Defence Connect amongst others said that the quadcopter UAV was delivered to an unnamed client, and was printed on Titomic’s TKF9000 machine, which has a print bed of 9 x 3 x 1.5 metres. According to Titomic, the titanium structure offers a rugged and lightweight design, and the craft is “well-suited for deployment in live combat situations.” The system incorporates Titomic’s patented additive manufacturingContinue reading→

Slovakian’s forgings company ZTS Metalurg under bankruptcy (US)

Posted on by

The company has focused since its establishment on products for use in the defence industry, ZTS METALURG, a.s. has many years of experience and a long tradition in the production of open and closed-die drop forgings as well as steel castings, cast steel and alloy steels.

The Czechoslovakian group decided to stop production at ZTS Metalurg in Dubenika Nad and Om. The company’s extinction ends on June 30 with more than 100 tribal employees. A spokesman for the news group Andrei Chirtak announced it. “Several dozen employees have the option to switch to Slovak company MSM Holdings, which is also part of the Czech group, or to Ostrava-based heavy machinery Vítkovice.Therefore, it is impossible to say exactly how Continue reading→

Chinese physicist says revolutionary technique means alloys can be developed in hours instead of years (US)

Posted on by

  • Inspired by early colour television, method can create thousands of alloys quickly
  • Leader of Beijing team says a ‘revolution in material science’ is close to hand

Chinese physicists say they have developed a method that can cut the time involved in the discovery of alloys from years to hours. The technique has led to the creation of high performance alloys, including the world’s toughest amorphous metal, or metallic glass, for use in extremely hot environments. The search for an alloy typically takes years, but now it can be done in less

Russian scientists create new aluminum alloy with flexibility, strength, lightness (US)

Posted on by

Lighter and faster aircraft and vehicles require lighter materials. One of the most promising materials is aluminum, or rather, aluminum-based composites.

Scientists from NUST MISIS scientific school “Phase Transitions and Development of Non-Ferrous Alloys” created a new strong Al-Ni-La composite for aircraft and automobile industry. Doping elements were added to aluminum melt, forming special chemical compounds that further formedContinue reading→

Chinese company produces large seamless circular forging for nuclear reactor (US)

Posted on by

China’s Taiyuan Iron & Steel Group (TISCO) announced Tuesday that it has produced a huge seamless circular forging with high-purity stainless steel, which will be used in a 4th-generation nuclear power unit. According to the company, the piece, 15.6 meters in diameter and 150 tonnes in weight, is the world’s largest in terms of size and weight. It will be used as the support ring for the core component of the pilot reactor for a 60 million kilowatts fast neutron reactor in Xiapu, Fujian Province. The forging is required to be able to bear a weight of 7,000 tonnes and a temperature of 650 degrees Celsius, and operate for four decades continuously. TISCO, located in Taiyuan of Shanxi Province, has supplied more than 50,000 tonnes of steel for nuclear power projects, including 45,000 tonnes of stainless stee

JINAN — A Chinese steel mill rolled off the world’s largest seamless ring forging piece, which was developed especially as the key part of a nuclear power unit. The loop-shape stainless steel piece, produced by the ShandongContinue reading→

U.S. Department of Defense develops advanced alloys for the next generation of infrared imaging technology (US)

Posted on by

As part of a U.S. Department of Defense Multidisciplinary University Research Initiative effort, Arizona State University Professor Yong-Hang Zhang will study the quality and stability of silicon-germanium-tin alloys and develop innovative device architectures for infrared applications. 

Brass, bronze and steel are metal alloys in which the combination of chemical elements — copper and zinc, copper and tin, iron and carbon, respectively — create unique properties, such as high strength and corrosion resistance, that can be used for particular purposes.  Arizona State University Professor Yong-Hang Zhang and Associate Professor Andrew Chizmeshyaare exploring these purposes as part of a U.S. Department of Defense Multidisciplinary University Research Initiative effort. They will study the fundamental material properties Continue reading→

Scott Schiffres Earns Award to support research to find intermetallic alloys that cool more quickly (US)

Posted on by

Assistant Professor of Mechanical Engineering Scott Schiffres has received a National Science Foundation CAREER Award to support research to find intermetallic materials (alloys) that cool more quickly than materials in current use

Mechanical engineer looks for alloys to dissipate heat more quickly than materials in current use

Anyone who has had a computer or cellphone overheat will appreciate the research that Scott Schiffres, assistant professor of mechanical engineering, is conducting with support from a five-year, $500,000 National Science Foundation CAREER Award. His project, which will be fully underway in the fall, is titled “Intermetallic Interfacial Thermal Transport for Advanced Electronics Manufacturing,” and his goal is to find new alloys that form intermetallics – metal alloys with defined crystal structures – onto silicon with thermal properties that can dissipate Continue reading→

Dunkirk Specialty Steel receives $10M investment for modernization (US)

Posted on by

Dunkirk Specialty Steel LLC, a leading U.S. manufacturer of semi-finished and finished specialty steel products, unveiled several state-of-the-art upgrades and modernization efforts at its Dunkirk facility. These renovations are the result of a $10 million capital investment from parent company Universal Stainless and Alloy Products, Inc., and collaborative efforts by the County of Chautauqua Industrial Development Agency, City of Dunkirk Department of Development, and NYS Empire State Development. The 800,000 square-foot facility has installed a new $10 million bar turn and burnish line, as well as a new General Electric phased array nondestructive testing system. The addition of the specialty equipment from Germany and Japan makes the Dunkirk-based unit finishing cell the most advancedContinue reading→

Hybrit project aims to ‘revolutionise iron and steelmaking’ (US)

Posted on by

A project called Hybrit is aiming to revolutionize the iron and steelmaking by removing fossil fuels from the process.

The initiative says it is developing methods to replace coking coal, which is traditionally needed for ore-based steelmaking, with hydrogen. Executives involved in the project will be presenting a number of seminars at Hannover Messe next week. Leading companies from the industry – such as SSAB, LKAB and Vattenfall – plan to replace coking coal with fossil-free electricity and hydrogen, developing what would be the world’s first fossil-freeContinue reading→
