Hall-Petch strengthening in ultrafine-grained Zn with stabilized boundaries Open
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 exp…
