Prof. Eugene Rabkin of the Faculty of Science and Materials Engineering and his colleagues of the George Mason University, have set a new standard for the strength of metallic materials. The study, published in the journal Nature Communication, paves the way for studying the behavior of metallic materials under high pressure.
The research investigated the mechanical properties of nanometer-sized nickel nanoparticles. The maximum strength of these particles, 34 Giga-Pascal, is three times higher than that of micronized iron fibers, which are the highest-strength metal structures ever measured. This achievement is based on unprecedented control of the structure of particle walls and coatings in a shell made of nickel oxide.
