The changes of microstructure of aluminum alloy 6111 sheets under the influence of pulse and pulse-static electrohydraulical stresses are explored. The dependences of thegrain size on the strain extent are defind. The increase of the medial grain size, bimodality of microstructure with definite strain extents and superplasticity behavior with pulse-static electrohydraulical stresses are considered.
Keywords: microstructure, alloy 6111, pulse electrohydraulical treatment, grain size, recrystallization, grain boundary sliding.
