Aluminium alloys have unique material properties and are indispensable materials in aircraft manufacturing and space technology. With the help of high-resolution electron tomography, researchers at TU Graz have for the first time been able to decode mechanisms crucial for understanding these properties. The research results have recently been published in Nature Materials.

How Quantum mechanics and Monte Carlo methods helped when the tomographic analysis provided an image which, surprisingly, could not be interpreted according to the previous level of knowledge, is explained in the TU Graz news article on the TU Graz website.
