A surprising discovery, 81 years after the bombing of Hiroshima, is capturing the attention of the scientific community. Researchers have identified a previously unknown metallic alloy that was formed only thanks to the extreme temperatures and pressures of a nuclear explosion.
Experts believe the material could help develop new metallic alloys and better understand the processes that occur during nuclear explosions.
Temperatures reaching several thousand degrees Celsius and the powerful shock wave melted the city's concrete, steel, glass and other materials. When the molten mass cooled almost instantly, glass particles known as "hiroshimaites" were created.
It is within these particles that a team led by Professor Luca Bindi of the University of Florence discovered a metallic structure that had never been documented before. Analysis with electron microscopy and X-ray diffraction showed that it is a rare alloy of iron and silicon with a very unusual atomic organization.
According to researchers, such extreme conditions are almost impossible to reproduce in the laboratory, so the nuclear bombardment created a unique materials science "experiment."
Experts emphasize that the goal of the study is not to glorify nuclear weapons, but to understand how matter behaves under the most extreme possible conditions. In the future, the knowledge gained could help develop more resistant materials for industry, energy and space technology.
