Creep properties of aluminium processed by ECAP

Original language description

The creep behaviour of pure polycrystalline aluminium and single crystals processed bynequal-channel angular pressing (ECAP) was investigated in order to understand the relationshipsnbetween heterogeneity of microstructure and creep behaviour. Tensile creep testsnwere performed at 373 K on specimens processed by 1 and 4 ECAP passes. For comparisonnpurposes, the creep tests were also carried out on coarse-grained specimens. Microstructurenanalyses showed that application of ECAP technique on polycrystalline aluminium and singlencrystals led to the formation of significantly different microstructures even after a relativelynhigh number of ECAP passes. The different creep behaviour of ECAP-processed single crystalsnand polycrystalline aluminium is influenced by inhomogeneity of microstructure. Further,nthe creep behaviour of specimens processed by 4 ECAP passes is affected by grain-boundarynmediated processes like enhanced recovery of dislocations at high-angle grain boundaries inngrains finer than quasi-stationary subgrain size and grain boundary sliding.
