Characteristics of superplasticity in an ultrafine-grained aluminum alloy processed by ECA pressing
Source abstract
Abstract
Abstract Equal-channel angular pressing was used to process a commercial 1421 aluminum alloy at temperatures from 340 to 410 °C. An optimum ultrafine microstructure was achieved after pressing at 370 °C with an equiaxed grain size of ∼0.3–0.4 μm. Tensile testing showed this material is superplastic at 400 °C with elongations up to ∼1500%. Offsets in surface marker lines demonstrate grain boundary sliding is the dominant flow process.
