Scientists at the Institute of Iron and Steel Alloys of Moscow State Research Technical University in Russia mixed aluminum melt with nickel and lanthanum to create a new material that combines the advantages of composite materials and standard alloys: very flexible, strong and lightweight. Faster, lighter aircraft and vehicles require lighter materials, one of which is aluminum or aluminum-based composites.

Today, aluminum is mainly strengthened by the use of nanoparticles, but the process is very expensive and time-consuming, and the results may not be satisfactory. For example, it is possible that the strength has only increased by 5% to 20%, while the plasticity and other indicators have decreased by 10% or even several times. In addition, the nanoparticles themselves are too large, ranging from 100 nanometers to 1 micron, and their volume percentage is very small.

The solution of the National University of Science and Technology solves the problems of uneven reinforcement and low density of powder composites. If the melting process is adopted, the particle diameter of aluminum-nickel-lanthanum (Al-Ni-La) after crystallization will not exceed 30 to 70 nanometers. Due to the nature of crystallization, the particles will be evenly distributed to form a reinforced structure. As a result, the composite material will be stronger and more flexible than an analog reinforced with powder.

According to scientists, this material is mainly suitable for the aerospace and automotive industries, as well as for modern robot design such as helicopters, because it is important to reduce the weight of UAVs.

Because the resulting structure is very special, the material can also be used for complex parts manufactured by 3D printing. In addition, from an economic point of view, it may bring strategic significance, because at present, the main profit of the Russian aluminum industry comes from the export of primary aluminum, and the production of new high-tech aluminum materials with added value can enable Russia to expand the domestic and foreign aluminum consumption markets, thereby increasing revenue.

In 2030, the proportion of renewable energy used in electrolytic aluminum will be increased to more than 30%, and the implementation plan for the synergy of pollution reduction and carbon reduction will be issued.
