Influence of the Precipitation State on Thermal Stability of an Ultra-Fine Grained AlMnFe-Alloy Produced by Equal Channel Angular Pressing

Abstract:

An aluminum alloy with two different precipitation states was processed by Equal Channel Angular Pressing up to 16 passes. The thermal stability of the ultra-fine grain structure was examined during annealing at 300°C up to 1 h. As the present precipitates are coarse they don’t contribute to strengthening where as soluted elements improved the strength of the material. Additionally the soluted elements formed dispersoids upon annealing and thereby retarded softening.
