Theoretical Distribution of Slip Angles in an Aggregate of Face-Centered Cubic Crystals

Abstract

An analysis of the relative frequency of occurrence of any given slip-line angle in a plastically deformed polycrystal composed of face-centered cubic crystals is presented for the case of simple tension. The results are compared with those obtained for a polycrystal composed of crystals which have but a single mode of slip and with experimental results. The comparisons show that the differences between the results obtained by the two theories become greater as the stress is increased. The comparison of the face-centered cubic theory with experiment is somewhat better than that of the single-slip-mode theory, but the errors are appreciable.
