Influence of the Texture on the Al–6%Mg Alloy Deformation

The influence of the texture on material mechanical properties and deformation behaviour was widely discussed. (refer to Bunge, H.J. (1982). Texture Analysis in Materials Science Mathematical Methods ). Butterworths, London. In this work elastic properties (Young's modulus) of cold rolled Al–6%Mg alloy sheet were estimated taking into account lattice preferred orientations, which can be described by the orientation distribution function (ODF). The ODF was reconstructed from pole figures measured by means of neutron diffraction and was approximated by normal distributions (Savyolova, T.I. (1994) Zavodskaya Laboratoria 50, N5 , 48–52). The method used for calculation is able to express explicitly the polycrystalline elastic property via the single crystal property and the texture parameters. Stress–strain dependenc (deformation curves) was measured by means of uniaxial tensile tests for Al–6%Mg alloy samples with different tensile axis directions. Samples for uniaxial tests were cut at different angles to the rolling direction. The conformity between experimental and computed results is discussed.
