Top 2 Hottest Paper in Acta Materialia

Prof. Paulo Ferreira and Ph.D student Chris Carlton’s recently published paper in Acta Materialia entitled “What is behind the Inverse Hall-Petch Effect in Nanocrystalline Materials?” is attracting a wide attention from the scientific community. The paper shows that the Hall-Petch equation developed in the 50’s is just a particular case of a more general phenomenon, where the inverse Hall-Petch effect in nanomaterials can be predicted.
