Russia’s new aluminum-based composite material can realize drone weight reduction
According to foreign media reports, scientists at the Russian National University of Science and Technology MISIS have mixed aluminum melt with nickel and niobium to create a combination of composite and standard alloys. New materials: high toughness, high strength and low density. High-speed aircraft and vehicles require lightweight materials, and one of the most promising materials is aluminum or aluminum-based composites.
At present, aluminum alloys are mainly strengthened by nano-powders, but the process is costly and has a long cycle, and the final result may not be satisfactory. For example, the intensity may only increase by 5% to 20%, and the index of plasticity is reduced by 10% or more.
The research program of the Moscow State University of Science and Technology in Russia solves the problems of uneven reinforcement and low density of powder composites. The crystal size of the aluminum-nickel-niobium (Al-Ni-La) alloy after crystallization is between 30 and 70 nanometers by a melting process. The crystal grains are uniformly distributed to form an ultrafine reinforcing structure. Therefore, the composite is stronger than the powder reinforced aluminum alloy.
According to scientists, this material is mainly used in the aerospace industry and the automotive industry, as well as in helicopters, drones and other areas where weight loss is critical. Due to the very special structure formed, this material can also be used for 3D printing of complex parts.
In addition, from the economic point of view, the development of this material is of strategic importance. Because at present, Russia’s aluminum industry’s main profit comes from the export of primary aluminum, the production of new high-tech aluminum materials with added value, allowing Russia to expand the domestic and international aluminum consumer market, thereby increasing revenue.
