Textures and Mechanical Responses with Strain Path in FeP0 4
Résumé
We report extensive x-ray diffractometric measurements as well as conventional metallurgical and mechanical tests on thin steel sheets of FeP04 for deep drawability in order to identify key microscopic parameters that govern both texture evolution and mechanical response as function of the type of loading path. While Microhardness measurements, as expected show an evolution as function of material work hardening, the distribution of grain size seems to be unaffected by the different type of loading path. Quantitative texture measurements demonstrates a development of different texture components depending on the type of loading path used to achieve the plastic deformation. Indeed, when compared to as received samples significant variation was found on Poles density and orientation distribution function versus the type of applied stress states.
