Resumen:
Material bulk properties are primarily dictated by its composition and, secondly, by its microstructure, which depends substantially on the
production method. Complex manufacturing processes can produce almost any imaginable microstructure, however, they can be dicult to
achieve in terms of time, energy and/or cost. Finding manufacturing processes that can be applied industrially but with strong eects on
the microstructure, is one of the possibilities oered by Severe Plastic Deformation (SPD). SPD techniques such as ECAE, HTP and ARB
suer from diculties to large-scale technology implementation due to geometric and dimensional causes. Asymmetric rolling (AR) shows
itself as a technique that can overcome these limitations, imposing a large percentage of shear deformation, with a minimal change of cross
section of the sheet. In the present work, 1050 aluminum sheets and F138 stainless stell were studied by means of XRD, using synchrotron
radiation. Measurements of developed textures were correlated with dislocation density and domain sizes estimates, obtained through peak
broadening analysis. Pole Figures and Generalized Pole Figures were used to conduct a comprehensive analysis and comparison of the
microstructure developed by dierent SPD processes in these materials.
