As part of a research team, scientists at Moscow’s National University of Science and Technology MISiS (NUST MISiS) have found a way to make metal structures lighter. This has become possible with new strong material and its welding properties.
The research results were published in the Journal of Materials Processing Technology.
According to the scientists, they’ve managed to obtain a high-strength material from iron, which, despite processing, retains high welding properties and can form strong joints. This will allow using welding instead of bolted joints in car, plane and rocket construction, thus making metal structures lighter.
According to experts, to obtain a high-strength material, extra elements should be added to the metal’s chemical makeup. However, this significantly impairs the material’s ability to be welded.
NUST MISiS researchers have found a way to achieve a high strength of iron through its nanostructuring by deformation: grinding its internal structure by equal channel angular pressing. This way, the researchers have managed to increase the metal’s strength while maintaining its weldability.
Scientists believe that this study breaks new ground in studying nanostructured materials since the problem of nanostructured materials’ weldability is still in its infancy.
NUST MISiS scientists added that the research team involves experts working in laboratories throughout the world.
Laboratory of Hybrid Nanostructured Materials
The researchers want to continue working in this area using other welding technologies, various materials and nanostructured metal production methods.
