The Formation of Dislocation Structure and Nucleation of
Recrystallized Grains in an Aluminum Single Crystal

The relations between texture and microstrueture in rolled fcc metals and alloys are described. In materials with low stacking fault energy texture and microstructure together provide a consistent empirical description of the deformation process. In materials with intermediate and high stacking fault energy things are more complicated.
There are a number of textural and microstructural features which are not understood and which probably require a combination of texture and microstructure to be understood. A substantial effort is needed in order to establish this connection.

The Relation Between Texture and Microstructure in Rolled FCC Materials

The anisotropic constraint stress will be induced in the specimens of
thin sheets, when they are quenched below Ms temperature without external
stress. The characteristics of variant selection phenomenon were studied
under these conditions. The texture of &#x3B3; and &#x3B1; of ferrous alloys were
analyzed with X-ray method. The results obtained could be explained
satisfactorily with the Bain Strain model as follows:(1) Variant selection phenomenon depends on the orientation of the parent
phase and on the Bain strain associated with martensitic transformation.(2) Such variants that have the largest Bain strain components to the
sheet normal are selected predominantly, because the occurrence of variants
are prevented least of all under the anisotropic constraint stress.

Effect of Stress on the Variant Selection in Martensitic Transformation

The overall plastic response of a sheet can be simply
calculated from the knowledge of its various texture
components, the behavior of them being described by the
equations of continuum plasticity. It is shown, however,
that the classical assumptions used for combining the
elementary components can lead to significantly different
predictions of the sheet behavior.

Anisotropic Plastic Behavior Associated With Rolling Textures

The effects of hot rolling temperature and alloying elements
on the textures and <mml:math id="E2" xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mover accent="true"><mml:mtext>r</mml:mtext><mml:mo>&#x00AF;</mml:mo></mml:mover></mml:math> values of cold rolled and annealed extra
low carbon steel sheets have been investigated. The steels
examined were one extra low carbon Al&#x2013;killed steel and two Ti&#x2013;IF
&#x28;Interstitial Free&#x29; steels with or without phosphorus. &#x28;200&#x29;
pole figures and relative intensities of various reflections from
the rolling plane were determined for hot bands and annealed
sheets. The hot rolled textures are found, when finish-rolled at
about 900&#xB0;C, random regardless of the steels tested. when the
finish rolling temperature is lowered to the ferrite region temperature
of 750&#xB0;C, however, the principal preferred orientation of
&#x28;100&#x29;&#x5B;011&#x5D; is developed. <mml:math id="E3" xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mover accent="true"><mml:mtext>r</mml:mtext><mml:mo>&#x00AF;</mml:mo></mml:mover></mml:math> values of annealed sheets are decreased
with decreasing the finish rolling temperature. This could be
related to the presence of the stronger &#x28;100&#x29;&#x5B;011&#x5D; component,
which is originated from the texture inhomogeneity in the through
thickness direction of the hot bands at 750&#xB0;C. The steel having
the lower <mml:math id="E4" xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mover accent="true"><mml:mtext>r</mml:mtext><mml:mo>&#x00AF;</mml:mo></mml:mover></mml:math> value revealed the higher yield point elongation
which is closely related to the solute carbon content in the
steels. The major component of the recrystallization texture was
near &#x7B;554&#x7D;&#x3C;225&#x3E; irrespective of the steels tested, but the
intensity of &#x28;100&#x29;&#x5B;011&#x5D; component was increased with decreasing
the finish hot rolling temperature.

The effect of textures produced by various types
of deformation processing on gas barrier property of
copolymer film has been studied in the case of
ethylene-vinylalcohol (EVOH) resin which is known as
a semicrystalline polymer with low gas permeability.The heavily cold rolling and cold stretching give
rise to highly oriented molecular structures and
strong crystallographic textures, which reduce gas
permeability of the film at high humidity. It was
found, in particular, that the increased tri-axial
orientation type texture and resulting molecular
structure changes due to the plane strain compression
type deformation, such as rolling, improved greatly
the barrier property of the EVOH film.

Textures and Barrier Properties of Ethylene-Vinylalcohol Copolymer
Films

A method proposed by Bunge in which we assume a fit between the theoretical ODF and the isolated
expetal points was used to calculate the ODF from experimental data chosen in an arbitrary way in a pole
figure and an inverse pale figure space. In particular, this technique was used to obtain the ODF from the
measurements of three, two and one pole figures, from the data obtained using the reflection technique only or
transmission technique only, from inverse pole figures and from the photo showing the Debye-Scherrer rings.
Various tests described in this paper allows us to suggest an empirical rule indicating that the number of
experimental data points should be three times higher than the number of required series expansion coefficients
of the ODF. In addition, other factors, for instance, the strength of texture and the distribution of experimental
points are also important.

Textures have been measured by means of X-ray pole figures for high temperature
superconductor materials in both bulk and thin film form. Variations in the epitaxy of the
yttrium-based thin films are correlated with processing history and properties. Textures are
given for deformation-processed Bi-based material, which, when subsequently melt-proCessed,
exhibits high critical currents. The surface resistance of Tl-based films on a silver substrate
are correlated with the sharpness of the texture.
