Abstract

In the present study, the evolution of microstructure, crystallographic texture and their influence on mechanical properties of the Al�Li alloy, AA2195 has been studied. A novel hybrid processing route involving warm multi-axial forging (MAF) and subsequent warm rolling was employed. Different rolling procedures were followed to obtain optimal microstructure and properties. The processing conditions significantly influenced the course of evolution of microstructure and texture. A variation in tensile properties as a function of angle from RD for the differently processed samples was noticed. The tensile properties were closer to isotropic case for the samples deformed using a combination of MAF with cross rolling. By controlling grain size and texture through optimal processing, it was possible to achieve isotropic tensile properties in the AA2195 alloy. The processing conditions have also led to enhancement in strength, which has been attributed to grain boundary strengthening, precipitation strengthening and dislocation strengthening. © 2020 Elsevier B.V.
