XLV. The hole of preferred orientation in elasticity investigations

Abstract

Abstract The purpose of the paper is firstly to investigate the role of preferred orientation in the elastic properties of polycrystalline metals, and secondly to apply these considerations to some experimental results. The analysis is confined to metals in the cubic crystalline system constituted so that the preferred orientation has circular symmetry about the axis of a bar, expressions being derived for the apparent elastic constants of the bar in terms of the single crystal constants and an anisotropy index. The experimental results used for illustration relate to alloys of copper with members of the first long period and cover variations in the annealing processes used.
