Russian scientists made new aluminum materials
Can be used in the automotive industry to achieve light weight
According to foreign media reports, scientists at the Russian National University of Science and Technology MISIS in Moscow, Russia, mixed aluminum melt with nickel and lanthanum to make a composite material and standard alloy New material with advantages: very flexible, strong and lightweight. Faster and lighter aircraft and vehicles require lighter materials, and one of the most promising materials is aluminum, or aluminum-based composite materials.
Today, aluminum is mainly strengthened by using nanoparticles, but the process is very expensive and time-consuming, and the end result may not be satisfactory. For example, the strength may only increase by 5% to 20%, while the plasticity and other indicators have dropped by 10% or even several times. In addition, the nanoparticles themselves are too large, ranging from 100 nanometers to 1-2 microns, and their volume percentages are very small.
The National University of Science and Technology's solution solves the problems of uneven reinforcement and low density of powder composite materials. If the melting process is used, the diameter of the crystallized aluminum-nickel-lanthanum (Al-Ni-La) will not exceed 30 to 70 nanometers. . Due to the natural crystallization, the particles will be evenly distributed to form an enhanced structure. Therefore, the strength of the composite material will be greater and more flexible than the analogues of powder-reinforced materials.
According to scientists, this material is mainly suitable for the aerospace industry and the automotive industry, as well as for the design of modern robots such as helicopters, because reducing the weight of drones is crucial.
Because the structure formed is very special, the material can also be used for complex parts manufactured by 3D printing. In addition, from an economic perspective, it may bring strategic significance. Because at present, the main profit of the Russian aluminum industry comes from the export of primary aluminum, the production of new high-tech aluminum materials with added value can allow Russia to expand the domestic and foreign aluminum consumer markets, thereby increasing revenue.
