Production of Ultrafine Grained AlMnFe Samples by Confined Channel Die Pressing as Compared to Equal Channel Angular Pressing

Ultrafine grained material was produced by equal channel angular pressing and confined channel die pressing. Microstructure and mechanical properties of the obtained samples were compared. The different effects on microstructure evolution and mechanical properties from both processes are discussed.
