Phase Transformations and Inherited ODFs Implications for
Petrophysical Properties

The texture of a polycrystalline material is defined by the
orientation distribution function (ODF) of its crystallites. Besides
this, the misorientation distribution MODF of neighbouring
crystals may be important. Although this applies equally
to all crystalline materials, texture studies have extensively
been done in metals and not so much in ceramics and polymers.
This is partly due to experimental difficulties of texture
measurement in these materials which have only recently been
overcome. Besides this, two deviating definitions of the term
&#x201D;texture&#x201D; are being used. These are the &#x201D;shape texture&#x201D; in
ceramics and the &#x201D;chain texture&#x201D; in polymers.Textures in ceramics were studied quantitatively mainly in
hard magnetic materials. They are, however, also most important
in HTc-superconductors, in ferroelectrics, in transformation
toughened ceramics, in ceramic surface layers, copperbonded
Al2O3 substrates and probably in many others. Textures
in the crystalline part of polymers have been studied
quantitatively using ODF-methods. &#x201D;Momenta&#x201D; of the orientation
distribution function of the crystalline as well as the
non-crystalline part can, however, be obtained more easily by
physical methods. This is sufficient if the correlation between
preferred orientation and anisotropic properties is considered.
Texture formation by deformation is, however, related to the
complete orientation distribution function.

Textures in Non-Metallic Materials

Macroscopic texture changes were measured on cold rolled and recrystallized
samples of a 3004 alloy using X-ray pole figures converted into ODFs by means of the
standard spherical harmonics method. Local textures were also estimated using electron
diffraction techniques: TEM, SACP and EBSP. The initial recrystallized starting
material with a relatively strong cube texture was rolled to strains of 0.6 and 3, reducing
the cube component and increasing the &#x3B2;-fibre rolling texture components. On annealing
the subsequent recrystallization texture behaviour depends upon the prior strain and the
heating rate. After relatively low strains, particle stimulated nucleation occurred giving
rise to an almost random texture. After high rolling strains nucleation appears to occur
on both particles and in transition bands; the latter favour the creation of new cube
grains. Finally, low heating rates which allow extensive recovery before recrystallization
have been shown to decrease significantly the cube texture component.

Prediction of Plastic Properties of Rods From Individual Grain Orientation Measurements

High fluence nitrogen ion implantation into titanium at room temperature
results in the formation of titanium nitride precipitation. Electron
diffraction measurements reveal an implantation-induced texture of
titanium nitride precipitations. The experiments demonstrate a strong
coupling effect between the implantation-induced fibre texture and the
direction of implantation. The results of this investigation support the
assumption that the effect of implantation-induced texture is caused by
the process of seed selection by ion channeling.

The Orientation Distribution in Channel Die Compressed Al Single
Crystals as Studied by Microdiffraction Techniques in SEM and TEM

A laboratory prototype of a system for the measurement of texture on-line
in the manufacturing process of steel or aluminum is being built at
McGill University. In order to test the effect that the different measurement
geometry, i.e an angular dispersive reflection or an energy dispersive
transmission geometry, has on the calculation of the coefficients of the
orientation distribution function &#x28;ODF&#x29;, a number of simulated texture
measurements were done for both geometries. The effect of the measured
texture on the prediction of magnetic torque was also studied.In general, there is good agreement between the textures calculated
by simulating the two measurement geometries and the original texture
used to recalculate the pole figures from which the simulation data was
extracted. The results also showed that, for the slightly inhomogeneous
steel, the bulk magnetic torque predicted from the texture measurements
simulating the energy dispersive, transmission geometry was only slightly
better than that predicted from the angular dispersive, reflection geometry.
In the case of the inhomogeneous steel, the prediction from the transmission
geometry was significantly better than that of the reflection geometry. It
has been shown that measurement geometry for on-line texture analyzing
systems has a significant impact on the accuracy of the texture information
obtained and the prediction of certain property anisotropies, especially for
those sheet materials exhibiting significant through-thickness
inhomogeneity.

The Effect of Measurement Geometry for on-Line Texture Analyzing Systems

Textures measured on 2 Al alloys after hot and cold rolling are analyzed in detail. It is
shown that the texture strength and the intensity of the brass component increase with
increasing temperature. This is in good agreement with some texture predictions.
