The importance of microstructural heterogeneities in the work hardening of ultrafine-grained aluminum, studied by in-situ TEM straining and mechanical tests
Abstract
Technically pure aluminum was deformed by means of hydrostatic extrusion and incremental equal channelangular pressing in order to refine grains to a similar size. Different deformation routes resulted in microstructurevarieties in terms of grain boundary characteristics, texture and local defects arrangements. Thesevarieties affected the work hardening abilities measured macroscopically in the tensile test. In-situ TEM strainingexperiments were performed in order to capture dislocation occurrences in both samples and relate them todifferent values of strain hardening indices.As a next step, microstructure-work hardening dependence of multiple samples was evaluated. Our studyshows that work hardening in ultrafine-grained materials can be assured only if dislocations can interact witheach other. This is possible when particular deformation structures are established during the gain refinement ofthe material. These results give an insight how to design ultrafine-grained structures which are capable to furtherprocessing.
