Modelling the evolution in microstructure and properties during processing of aluminium alloys

A new work-hardening model for f.c.c. metals and alloys has recently been developed [Prog. Mater. Sci. 41 (1998) 129; Mater. Sci. Forum 331–337 (2000) 1231; Mater. Sci. Technol., 17 (2001) 376–388; K. Marthinsen, E. Nes, K. Nord-Varhaug, B. Rønning, in: J.B. Bilde-Sørensen, et al. (Eds.), Proceedings of the 20th Risø International Symposium on Materials Science: Deformation-induced Microstructures, Analysis and Relation to Properties, Risø National Laboratory, Roskilde, Denmark, 1999, pp. 405–410; Mater. Sci. Eng., submitted for publication]. In the present work this model will be applied to the processing of aluminium alloys, covering conditions typical of both hot deformation (rolling and extrusion) and cold rolling, the emphasis, however, will be on hot deformation. Alloying effects due to solid solution (multi-component systems) as well as particles (constituent particles and dispersoids) will be considered.
