A relationship between the tensile yield stress and grain size i.e., Hall-Petch (H–P) law, for an ultrafine-grained (UFG) Zn was experimentally evaluated for the first time. In reality, it is problematic to assess this prediction using experimental

Grain boundary (GB) strengthening of metallic materials faces limitations as grain sizes are reduced to the nanoscale, primarily due to the transition from the strengthening to the softening effects. Understanding the intrinsic mechanisms behind such

ABSTRACTThe Hall-Petch strengthening coefficient of face-centered cubic alloys has the potential to increase. Herein, we experimentally determined an unconventionally large Hall-Petch coefficient equal to 1100 MPa·µm1/2 and a large lattice friction
