Researchers at the Department of Energy’s Oak Ridge National Laboratory have received nine R&D 100 Awards in recognition of their <a href=""></a> significant advancements in science and technology.
The honorees were recognized earlier this month at the 55th annual R&D 100 Conference, sponsored by R&D Magazine.
The awards are known as the “Oscars of Invention,” according to an ORNL news release. They honor innovative breakthroughs in materials science, biomedicine, consumer products and more from academia, industry and government-sponsored research agencies.
This year’s nine honors bring ORNL’s total of R&D 100 awards to 210 since their inception in 1963.
ORNL researchers were recognized for the following innovations:
‒ ACMZ Cast Aluminum Alloys were developed by a team of researchers from ORNL with Fiat Chrysler Automobile U.S. and Nemak U.S.A.
“ACMZ aluminum alloys are a new class of affordable, lightweight superalloys capable of withstanding temperatures of almost 100-degree Celsius more than current commercial alloys while providing exceptional thermomechanical performance and hot tear resistance,“the release stated.
Common commercial alloys soften rapidly at high temperatures, limiting their use in next-generation vehicles, while other alloys that can withstand elevated temperatures are cost prohibitive and difficult to cast. ACMZ alloys were developed using a suite of atomic-level characterization and computation tools, resulting in what the release called, “a strong, stable and versatile material capable of withstanding the stressful conditions of next-generation high-efficiency combustion engines.”
The development team includes ORNL team leader Amit Shyam and ORNL’s J. Allen Haynes, Yukinori Yamamoto, Dongwon Shin, Adrian Sabau, Lawrence Allard, Thomas Watkins, Wallace Porter, James Morris, Shibayan Roy, Philip Maziasz, Dana McClurg, Charles Hawkins, Patrick Shower, Brian Milligan; Fiat Chrysler’s Gregg Black, Chris Glaspie, Seyed Mirmiran, Yi Liu and Lin Zhang; and Nemak’s Andres Fernando, Jose Talamantes and Jose Alejandro Gonzalez.
Funding for this project was provided by the DOE’s Energy Efficiency and Renewable Energy Office, Office of Vehicle Technologies.
‒ Additively Printed High Performance Magnets were developed by a team of researchers from ORNL and co-developed by Ames Laboratory Critical Materials Institute (CMI), Magnet Applications Incorporated, Tru-Design and Momentum Technologies.
“Additively Printed High Performance Magnets are the first rare earth bonded magnets created using the Big Area Additive Manufacturing method, allowing for rapid production with no size or shape limitations and minimal material <a href=""></a> waste. In contrast to more common sintered magnets that require the application of very high pressure to chemically reactive materials, bonded magnets are less expensive and resource-intensive to produce,” the release stated.
The magnet feedstock blends a magnetic powder with a nylon polymer and the finished magnets demonstrate comparable or better magnetic, mechanical and microstructural properties than bonded magnets created with traditional injection molding methods. Using the BAAM system reduces energy consumption, lowers production costs and conserves rare earth elements, which are widely used in electronics and are mined and processed overseas.
The development team, led ORNL’s Parans Paranthaman, includes Vlastimil Kunc, Ling Li, Brian Post, Orlando Rios, Michael McGuire, Brian Sales, Edgar Lara-Curzio, Amy Elliot, all of ORNL; Ames CMI’s Alex King, Thomas Lograsso and Ikenna Nlebedim; John Ormerod and Robert Fredette of Magnet Applications Incorporated; Rick Spears of Tru-Design; and Preston Bryant of Momentum Technologies.
This project was supported by the DOE’s Critical Materials Institute, an Energy Innovation Hub funded by the U.S. Department of Energy, Office of Energy Efficiency and Renewable Energy, Advanced Manufacturing Office.
‒ Filler Materials for Welding and 3D Printing were developed by ORNL in collaboration with the U.S. Army Tank Automotive Research, Development and Engineering Center.
