Description of the research topic:
The project deals with flat rolled Al products. The conventional thermo-mechanical processing (TMP) of Al alloy sheets generally involves casting, hot and cold rolling followed by recrystallization during final annealing. Each of these processes is characterized by microstructural transformations, which are specific for a particular process in the TMP chain. In turn, a variety of micro-structural features gives rise to many of the well-known properties of materials. The structure of polycrystalline metallic materials comprises various types of crystal defects on a length scale ranging from nanometers to millimeters and connects the macroscopic properties of materials to the atomic scale. In large scale production, the properties of a particular material are very often delimited by the processing route. One of the principal reasons for such limitations is that polycrystalline materials subjected to conventional thermo-mechanical processing undergo various microstructural transformations leading to the presence of preferred crystal orientations, called crystallographic texture. The evolution of crystallographic texture in face centered cubic (FCC) materials such as Al alloys accounts for strong anisotropy in the finished products since the deformation in various crystals flows in different ways. Particularly, materials with strong anisotropy of plastic strain ratio cannot ensure the enhanced requirements for deep drawing processes involved in stamping of complex components. The proposed project aims to make the fundamental breakthroughs needed to enable the development of efficient materials with minimum anisotropy via microstructure and texture optimization. The goal of this research can be reached via detailed investigation of both microstructure and texture evolution during processing rout by various analytical techniques such as scanning electron microscopy and electron backscatter diffraction (EBSD), which enable modelling the plastic anisotropy in corresponding materials.
