DuAlumin-3D: An Additively Manufactured Dual-Strengthened Aluminum Alloy Designed for Extreme Creep and Fatigue Resistance
Established in 1963, the R&D 100 Awards is the only S&T (science and technology) awards competition that recognizes new commercial products, technologies, and materials for their technological significance that are available for sale or license. The R&D 100 Awards, celebrating the program's 60th Anniversary this year, has long been a benchmark of excellence for industry sectors as diverse as telecommunications, high-energy physics, software, manufacturing, and biotechnology. This 2022 R&D 100 winner is listed below, along with its respective category.
Category: Mechanical/Materials
Developers: Oak Ridge National Laboratory
Co-Developers: General Motors, Beehive Industries
United States
Product Description:DuAlumin-3D is a new aluminum alloy designed to take advantage of the rapid solidification characteristics of additive manufacturing to produce a dual-strengthened microstructure, resulting in a superior combination of tensile, creep, fatigue, and corrosion properties, particularly at extreme temperatures (300°C-400°C), compared with commercial alloys.
