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 σ 0 (ε) is proportional to ε and k(ε) having negative variation with ε 1/2 . A new equation for flow stress as a function of true strain (ε) and grain size (d) has been evolved for this alloy.
