Molecular Dynamics Study on the Inverse Hall-Petch Relationship in Nano-Polycrystalline Al-Zn-Mg Alloys.
Nanocrystalline Al-Zn-Mg alloys are pivotal for next-generation aerospace and automotive applications that require superior strength-to-weight ratios. However, optimizing their mechanical properties at the atomic scale remains a challenge because classical strengthening theories break down. This study employs molecular...
