Abstract

A new form of deformation mechanism map is introduced based on grain size. Maps are developed for pure aluminum at two different homologous temperatures, and the relative contributions of the various deformation processes are estimated as a function of stress at different grain sizes. A simple method of constructing these maps is presented, requiring only a knowledge of the relevant constitutive equations for the various mechanisms and a minimum of calculation.
