Abstract
The equal channel angular extrusion (ECAE) is a process used to improve the mechanical properties of materials. Key parameters to achieve this objective are mainly the geometrical dimensions of the extrusion die and the extrusion parameters such as extrusion rate, the back pressure, the applied load, etc…. The characterization by the use of X-ray showed that the sample extruded at 45 mm/min, and which has light and dark bands due to the stick-slip phenomenon polymer, has sheared in the direction of approximately 45° to the extrusion direction. The using of the Fit2d software can locate the families of crystal planes (hkl) of the PP. Observations by X-ray in the direction of flow have shown the existence of three planes (040), (130) and (111). On the other hand, by the observation in the transverse direction revealed the existence of another plane (131).
