Abstract

The dependence of flow stress on grain size was studied in a Cu-1%Cd alloy. The Hall-Petch constants are related to true strain in such a way that σ0(ε) is proportional to ε and k(ε) having negative variation with ε1/2. A new equation for flow stress as a function of true strain (ε) and grain size (d) has been evolved for this alloy. © 2007 Elsevier B.V. All rights reserved.
