Recently, according to foreign media reports, scientists at the Institute of Iron and Steel Alloys of the Moscow State Research Technological University in Russia have created a new material by mixing molten aluminum with nickel and lanthanum. This material combines the advantages of composite materials and standard alloys: it is very flexible, strong, and lightweight.
Currently, aluminum is mainly strengthened using nanoparticles, but this process is both expensive and time-consuming, and the final result may not meet expectations. For example, the strength may only increase by 5% to 20%, while indicators such as plasticity decrease by 10% or even several times. In addition, the nanoparticles themselves are too large, ranging from 100 nanometers to 1 micrometer, and their volume percentage is very small.
The solution from the National University of Science and Technology (NUST) addresses the problems of non-uniform reinforcement and low density in powder composite materials. If a melting process is used, the aluminum-nickel-lanthanum (Al-Ni-La) particles will not exceed 30 to 70 nanometers in diameter after crystallization. Due to natural crystallization, the particles will be uniformly distributed to form a reinforced structure. Therefore, this composite material will be stronger and more flexible than similar materials reinforced with powder.
According to the scientists, this material is mainly suitable for the aerospace and automotive industries, as well as modern robot design, such as helicopters, where reducing the weight of drones is crucial.
Due to the very specific structure formed, the material can also be used for complex parts manufactured by 3D printing. In addition, from an economic perspective, it may have strategic significance, as the Russian aluminum industry currently mainly profits from primary aluminum exports. Producing new high-tech aluminum materials and adding value will enable Russia to expand its domestic and foreign aluminum consumer markets, thereby increasing revenue.
