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 sigma(0)(epsilon) is proportional to s and k(epsilon) having negative variation with epsilon(1/2). A new equation for flow stress as a function of true strain (epsilon) and grain size (d) has been evolved for this alloy. (c) 2007 Elsevier B.V. All rights reserved.
