Abstract
Mechanical behavior and microstructural evolution in an as-cast coarse-grained aluminum alloy 7475 were investigated during uniaxial compression and multidirectional forging (MDF) carried out at the temperature of 490оС and the strain rate of ~10–4 s–1. It has been shown that the deformation route provided by MDF is more suitable for flow softening and grain refinement in the present alloy under high-temperature deformation conditions.
