Different creep behaviour and microstructure of ECAP aluminium with the identical ECAP history

Popis výsledku v původním jazyce

Experiments were conducted on extremely coarse - grained Al (99.99%. The subsequent extrusion passes were performed by route A (no rotation between subsequent passes) up to 2 ECAP passes. Creep tests in tension were performed on the as-pressed samples at473 K and applied stress 15 MPa. It was found that the ultrafine - grained Al specimens with the same ECAP history showed the scatter in the creep properties. In this work the microstructure changes within grains with different crystallographic orientations and near their high - angle boundaries of coarse-grained state in the sample after different ECAP passes were studied. Mutual comparison of the results of microstructural characterization of microstructure of as-received coarse-grained state and thestate after different ECAP passes were performed. It is concluded that the scatter in creep properties could be influenced by inhomogeneity of ECAP microstructure.
