In this work, an experimental analysis of the behavior of the texture of
deformation and evolution of grain size, which is characteristic for a given
material and the processing to which it has been subjected, is presented. In this
case, samples of copper, steel 304 and aluminum are studied. Analyzing the
evolution of planes and preferential directions during a deformation process
typical of a stress test in different representative zones of the stress-strain curve
until reaching the rupture. In which, the microstructural evolution of the
samples is evidenced using optical and electronic microscopy and the analysis
by EBSD (Electron Backscatter Diffraction), with this last experimental technique,
the poles and inverse poles figures are determined to obtain the preferential
orientations in which certain crystalline directions align with the main directions
of the plastic flow of the material to obtain a greater information of the
anisotropic response and microstructural evolution, during the process of
deformation of the material subjected to different efforts representative of the
deformation stress curve.
