Abstract : This report deals with those structural state factors which determine the deformation and softening characteristics of face-centered cubic metals. Structural factors which affect the ability of the material to cross-slip appear to determine the deformation characteristics. Of particular mention in this regard is the effect of a precipitate produced either prior to or during the deformation of the material. The main structural factor which appears to effect the softening characteristics of F.C.C. metals is the interaction of precipitate with the dislocation structure during the annealing operation. This dynamic precipitate-dislocation interaction also determines the mechanical property stability of the material. One factor which determines the intensity of this interaction is the thermal and strain stability of the precipitate. (Author)
