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 ฯƒ 0 (ฮต) is proportional to ฮต and k(ฮต) having negative variation with ฮต 1/2 . A new equation for flow stress as a function of true strain (ฮต) and grain si
