Kornfeinung, Verfestigung und Duktilität zweiphasiger Al-Legierungen, hergestellt durch starke plastische Verformung
Zusammenfassung der Projektergebnisse
The purpose of the project proposed here is to explore the possibility of improving the ductility of severely plastically deformed ultrafine-grained Al alloys by controlling the influence of second phase particles (precipitates) and solute elements on microstructure refinement, mechanical behavior (strength, ductility, strain hardening) and thermal, structural, and mechanical stability. From the planned investigations contributive relationships between microstructure, mechanical properties (especially strain hardening and strain rate sensitivity), and SPD processes in two phase Al alloys (Al-Mn-Fe and Al-Zn-Mg) will be experimentally and theoretically established. It is expected that the outcome of the project will deepen our understanding of particle containing ultrafine grained materials and provide new avenues for the processing of stable nanocrystalline materials with desired properties.
