Deformation behaviour and microstructure-mechanical-property correlations for RR58 aluminium alloy

Processing of costly and special materials developed for specific applications needs very careful processing for producing net-shape or near-net-shape components without defects and with controlled microstructures on a repeatable basis. Hence, deformation processing requires science-based methodologies to understand and control the workability and microstructural changes under actual processing conditions. In the present paper, atomistic and systems approaches have been used to analyse the deformation processing of RR58 aluminium alloy in the complete range of strain rates and temperatures involved in industrial metal-forming processes. Both of these approaches have yielded comparable results and can be applied quite easily to the processing of different materials.
