Abstract
A revised Hall-Fetch Relationship, made by adding new microparameters, is proposed. These parameters, representing the contribution of dislo cations, can be obtained from the analysis of the X-ray diffraction pr ofile. The flow stresses calculated at various strain stages according to the equation coincide very well with the measured data.
