The mechanical properties of Zn–Fe–Li alloys after grain refinement are significantly improved, following the Hall–Petch equation [33]: (3) σ y = σ 0 + k d − 1 / 2 Where σ y is the friction stress, σ 0 is the frictional stress, k is the slope, and d is the grain size. From the Hall–Petch formula, a smaller grain size results in a ...

This book concentrates on both understanding and development of nanocrystalline materials. The original relation that connects grain size and strength, known as the Hall-Petch relation, is studied in the nanometer grain size region. The breakdown of such a relation is a challenge. Why and how to overcome it?
