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

  • 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)

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)

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)

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)

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)

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)

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

Chinese group sparks oversupply fears in steel market (US)

Fears of oversupply in the Chinese steel market, the world’s biggest, rose sharply on Thursday after the country’s largest producer suffered a plunge in profits.

Baoshan Iron and Steel Co, the main listed arm of the world’s second-largest steelmaker BaoWu Steel Group, was hit by slowing demand for the grey metal and higher costs. The 46 per cent plunge in net profits to Rmb2.7bn ($400m) in the first quarter compared with the same period last year adds to supply concerns. The possibility of output exceeding domestic demand in China, which accounts for half of global steel production, raises the prospect of the country again using exports as a pressure valve, flooding international markets with excess material and suppressingContinue reading

Framatome invests €12.6 million on its site of Ugine and inaugurates its new VAR furnace

On Wednesday April 10, the new VAR furnace was inaugurated in the presence of government representatives, elected officials, partners from the Auvergne-Rhône-Alpes region and employees. After two and a half years of work, the Ugine Framatome site (Fuel BU) is now equipped with an additional VAR (vacuum arc remelting) furnace and a new control cabin, allowing various site alloys to be melted using state-of-the art equipment.

“This investment of 12.6 million euros over four years is vital for the sustainability of our activities, serving our customers in the nuclear, aerospace and metallurgical industries,” commented Marc Lo Pizzo, Site Director. “I am proud of this investment, and the professionalism of the teams mobilized to complete this project. This new equipment is an additional way to meet our national and international customers’ needs, and will be a driver of progress and future development for Ugine and its 300 employees”
