Avaliação da textura cristalográfica de um arame perlítico torcido e não torcido

Abstract

Pearlitic steel is used in extreme conditions. The study of the texture in that steel when it undergoes mechanical transformations such as the torsion process, aims to investigate a physical phenomenon known as delamination, which in the literature, there is not much information and is something unknown. The study of texture allows an acquisition of knowledge that makes it possible to obtain many important information such as anisotropy among other information. X-ray diffraction can be used with numerous other techniques that allow obtaining very expressive and important information about these materials. The study of the texture made possible a further investigation on the propagation of cracks and how the material may behave when subjected to mechanical stresses such as torsion, machining, drawing, forging and extrusion. The use of SEM including the EBSD technique and X-ray diffraction allowed a new way of representing the texture of the material as an example the micro and macro texture.
