Simulation of Texture Development During Deformation of Quartzite

Tyre industry wishes always wires with best mechanical performances. This
continuous improvement of the performances needs the knowledge and the understanding
of the deformation process of the wire. To reach this goal, it is useful to know the
cristallographic texture and its evolution during the drawing process.The depth of penetration of X Ray not being very important (about some tens of
micrometers or more in metal, depending on he absorption &#x5B;1&#x5D;), the X Ray examination
can be considered as a superficial one for large wires (about a millimeter diameter or
more).On the other hand, if we consider thin wires, it can be said that X-ray can penetrate
deeply and even reach the core of the wire. In this case the information we get from the
diffracted intensities is a mean orientation factor K<mml:math id="E1" xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mrow><mml:mrow><mml:mo>(</mml:mo><mml:mrow><mml:mi>&#x03D5;</mml:mi><mml:mtext>,</mml:mtext><mml:mi>&#x03C8;</mml:mi></mml:mrow><mml:mo>)</mml:mo></mml:mrow></mml:mrow></mml:math> &#x5B;2&#x5D; subject to modification
caused by the absorption and the diffracting volume effect. This mean factor will be
closer than that of the surface, especially when the wire becomes larger or the texture
gradient gets lower.To measure with accuracy the texture of steelcord and its change, we have
developed a X-ray diffraction procedure to obtain the texture evolution across the wire
radius for each important step of the drawing process &#x5B;2,3&#x5D;. This evolution is studied
according to some drawing parameters.

Evolution of the Texture in Steelcord

The ability to measure individual orientations from crystallites enables a more
complete characterization of the microstructure. A primary obstacle to the use of
single orientation measurements is the large investment of direct operator time
necessary to obtain a statistically reliable data set. The most viable technique for
obtaining individual orientation measurements is electron backscatter Kikuchi
diffraction (BKD). Current technology requires an operator to identify a zone axis
pair in a BKD pattern. This paper describes research in progress to automate the
identification of lattice orientation from BKD patterns by identifying the planes
associated with the bands that appear in the patterns. This work considered FCC crystal
symmetry.

Automated Lattice Orientation Determination From Electron
Backscatter Kikuchi Diffraction Patterns

Development of texture and microstructure of commercial high
permeability silicon steel during rolling and recrystallization were studied by
Orientation Distribution Functions &#x28;ODFs&#x29; and optical and electron
microscopy. The present results confirm former single crystal results that
large &#x7B;111&#x7D;&#x3C;112&#x3E;-oriented cold rolled grains containing shear bands are the
origin of the Goss texture after primary and secondary recrystallization. The
formation of &#x7B;111&#x7D;&#x3C;112&#x3E;-oriented grains during intermediate cold-rolling
can be explained by relaxed constraint models. In the case of iron-silicon
their orientation density is still enhanced by the transformation of the shear
texture in the hot band subsurface during cold rolling. Formation of Goss
nuclei in shear bands together with growth preference of the Goss nuclei in
these grains leads to a primary recrystallization texture containing Goss
grains.

Influence of Texture and Microstructure Inhomogeneities on the
Origin of Goss Texture in Silicon Steel

Hot rolled steel sheets with high r&#x2013;value were developed. The steel
was rolled with more than 50&#x25; reduction at each final three stands near
the A r3 temperature. The condition was investigated by a computer
simulation model for micro&#x2013;structures and a transformation texture
model. Dynamically recrystallized &#x3B3; with random texture transforms to
&#x3B1; with random texture or that with &#x7B;110&#x7D;&#x3C;001&#x3E; orientation. Average
r&#x2013;value reaches 1.0 or more with random orientation. On the other hand,
more than 1.2 of average r&#x2013;value was maintained when the &#x7B;110&#x7D;&#x3C;001&#x3E; &#x3B1; was hot rolled giving recrystallized &#x7B;112&#x7D;&#x7E;&#x7B;111&#x7D;&#x3C;011&#x3E; &#x3B1; texture.

Rolling Conditions for High R&#x2013;Value of Hot Rolled Steel Sheets
Analyzed by Computer Simulations Model for Micro&#x2013;Structure

Cup tests were performed on hot rolled AA3004 alloy and
the profile of the ears were measured. ODF&#x2032;s were
determined from slices cut parallel to the cup wall at 0&#xB0;, 45&#xB0; and 90&#xB0; to the initial rolling directions. These
determinations were compared to the Taylor-Bishop-Hill
deformation model using full and relaxed constraints. The
measured ear profile was compared to a continuum cup height
calculation and the agreement was very good.

Textural Evolution During Draw-Cup Tests of Thick Aluminum 3004 Alloy Sheet

Regular grain oriented 3 wt.&#x25; silicon steel sheets of 0.30mm thick, having
orientations near &#x28;110&#x29;&#x5B;001&#x5D;, were cold rolled to 0.050mm thick and their 0.100 and
0.050mm thick foils were annealed in order to study the changes in rolled textures,
recrystallized texture and magnetic properties with decreasing the sheet thickness.
the results are summarized as follows:&#x28;110&#x29;&#x5B;001&#x5D; grains of recrystallized sheets are changed to &#x28;111&#x29;&#x5B;112&#x5D; with cold
rolling and &#x28;111&#x29;&#x5B;112&#x5D; grains of cold rolled sheets are restored to &#x28;110&#x29;&#x5B;001&#x5D;
with annealing.The stronger &#x28;111&#x29;&#x5B;112&#x5D; textures are formed in the cold rolled sheets,
the stronger &#x28;110&#x29;&#x5B;001&#x5D; textures are developed in the recrystallized sheets, when the
cold rolled sheets of 0.100 and 0.050m thick were annealed to and above 600&#xB0;C for
1 hour, recrystallization occurred to show resoring the magnetic properties to those
of the initially secondary recrystallized 0.30mm thick sheets with forming similary
strong &#x28;110&#x29;&#x5B;001&#x5D; textures.

Rolled textures and Magnetic Properties of Regular Grain Oriented 3&#x25; Silicon Steel With Very Low Thickness

The aim of this paper is to explain the experimental techniques required for the operation
of the EBS system. Also, by use of suitable examples, its potential as a tool for the rapid
analysis of the microtexture and mesotexture of materials is demonstrated.

Experimental Aspects of the Use of Electron Back Scattering for Characterisation of Microtexture
and Mesotextures

The recrystallization textures of cold drawn aluminium alloys
were determined by means of the orientation distribution functions
&#x28;ODFs&#x29;. The changes in texture with annealing temperature were
interpreted by examining the interrelation between recrystallization
and precipitation. The drawing textures of all the specimens
are mainly composed of the &#x3C;111&#x3E; fiber component. In the case of
Al-Si, silicon exists in the solid solution at high and medium
temperatures &#x28;623-723K&#x29;, therefore, the &#x3C;111&#x3E; component is
sharpened and the recrystallization textures are composed of the
strong &#x3C;111&#x3E; component and the weak &#x3C;100&#x3E; one. On the other hand,
precipitation of silicon participates in recovery and recrystallization
at low temperatures &#x28;523-573K&#x29; so that the &#x3C;100&#x3E; component
nearly equals to the &#x3C;111&#x3E; one in intensity. Al-Fe shows the
strong &#x3C;111&#x3E; &#x2B; weak &#x3C;100&#x3E; fiber texture in the all ranges of
annealing temperatures, though the &#x3C;111&#x3E; component is stronger at
a high temperature &#x28;723K&#x29;, where precipitation occurs after
recrystallization, than at low and medium temperatures &#x28;573-673K&#x29;,
where it does before recrystallization. For Al-Fe-Si, the recrystallization
textures are almost the same as Al-Fe except for
weakening in orientation density.
