Abstract

A survey of earlier work has revealed that no satisfactory explanation of the relation between texture and earing in face-centred cubic metals has so far been advanced. A simple theoretical approach using the maximum resolved shear stress criterion for slip on {111} 〈110〉 systems is described which enables all the important features of the earing of cups pressed from single crystals to be predicted. Good agreement between the predictions and experimental measurements on cups pressed from aluminium single crystals has been obtained. Extension of the theory to polycrystalline material is discussed briefly and it is concluded that the predictions are completely consistent with practical observations.
