Abstract

The article presents the results of studies of the influence number of passes and single crimps during rolling strips, respectively, in helical rolls and longitudinal-wedge mill on the parameters of the microstructure of aluminum alloy 2017. Comparative assessment grain sizes of ultrafine-grained structure after rolling strips with different passes in the helical rolls and deformation of the longitudinal-wedge mill at a deformation temperature of 400 °C. It is shown that the aluminum alloy sheet material 2017 provides the formation of a homogeneous ultrafine grain structure with a grain size of about 240 nm, which leads to an increase strength and plastic properties of the alloy.
