Two commercial Aluminium alloys with high Mn content were investigated in three
different precipitation states. The rolling textures possess a portion of random orientations
that is proportional to the volume fraction of larger particles. It is therefore identified with
their deformation zones having about double the diameter of the particles. The recrystallization
textures are weak for high annealing temperatures and show the more retained rolling
texture the more the temperature is lowered. This is interpreted as a matter of nucleation site.
But also growth mechanisms influence the texture evolution. Minor texture components are
characteristic for the different conditions.

The Effect of Particles on Texture Evolution in Commercial AlMn

Diffraction patterns of multiphase and low-symmetry materials
are characterized by a manifold of reflections with high peak overlap, hindering
individual pole figure measurements by conventional X-ray technique. These
difficulties can be overcome by using neutron diffraction with its advanced
position-sensitive detector technology and by separating overlapping peaks by
means of profile fitting methods. The paper describes appropriate instrumental
equipment and a semi-automatic procedure for individual pole figure data analysis
to be performed interactively on a PC. Pole figure results of a two-phase
chalcopyrite ore are given.

A Review of the Analysis of Local Texture by ELectron Diffraction

Work done for this paper centres around two themes: 1) the
characterization of the through-thickness inhomogeneity of texture
observed in certain deep drawing steels, and 2) attempting to understand to
what extent the presence of this inhomogeneity affects the correlation
between the texture and the bulk plastic anisotropy of the specimens. For
this, the textural inhomogeneities in three deep drawing steels, two
interstitial free and one aluminum killed, were measured and described
using the orientation distribution function (ODF). The bulk plastic
anisotropies of these specimens were obtained through the measurement of
the r-value. The impact of the measured inhomogeneities on the bulk
properties was analyzed by comparing the r-value anisotropies calculated
using a series expansion method from the various texture measurements
made through the sheet thicknesses to the experimental r-values. It was
observed that the textural inhomogeneities in the specimens were slight and
consisted mainly of small Goss components at the surface and sub-surface of
the sheets, which were not observed at the sheet centres. The impact of
these inhomogeneities was small, but generally the r-value predictions
made from the textures measured at the sheet centres were better correlated
with the experimental r-value anisotropies.

Development of Recrystallization Texture in Deep Drawing
Steels, Measured by X-Ray and Single Orientation in SEM

The texture development in Al-2.3&#x25;Li during cold rolling, cross
rolling and subsequent recrystallization annealing is investigated
by means of X-ray pole figures and ODF analysis. The
results are discussed in terms of Taylor-type deformation models
and of nucleation and growth models for recrystallization.

Texture Development in Al&#x2013;2.3&#x25; Li

Model calculations of texture formation during cross-rolling are carried out based on the full&#x2013;constrained Taylor theory. Three variants of cross&#x2013;rolling were considered i.e. two&#x2013;stage, four&#x2013;stage and multi&#x2013;stage
rolling. Three types of glide systems &#x7B;110&#x7D;<mml:math id="E1" xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mrow><mml:mrow><mml:mo>&#x2329;</mml:mo><mml:mrow><mml:mtext>111</mml:mtext></mml:mrow><mml:mo>&#x0232A;</mml:mo></mml:mrow></mml:mrow></mml:math>, &#x7B;112&#x7D;<mml:math id="E2" xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mrow><mml:mrow><mml:mo>&#x2329;</mml:mo><mml:mrow><mml:mtext>111</mml:mtext></mml:mrow><mml:mo>&#x0232A;</mml:mo></mml:mrow></mml:mrow></mml:math>, &#x7B;123&#x7D;<mml:math id="E3" xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mrow><mml:mrow><mml:mo>&#x2329;</mml:mo><mml:mrow><mml:mtext>111</mml:mtext></mml:mrow><mml:mo>&#x0232A;</mml:mo></mml:mrow></mml:mrow></mml:math> and all possible combinations of them were compared.
The calculations were based on calculated orientation changes for grid points throughout the orientation space, taking the spread range according to the non&#x2013;unique solution of the Taylor theory into account.
