Processing sheets and wires by continuous high-pressure torsion

Continuous high-pressure torsion (HPT) method was applied to pure Al (99.99%) and O?4Zl)�@Ul&�(�E4OZZ)g�<bWaaV)e?bVOb4)?bW?c)caCF 6�CF�4O?PScaSRT)CaSdSCS plastic deformation and thus for production of ultrafine grained microstructure as the conven- tional HPT. Furthermore, CHPT provides a means to process sheet and wire of the materials in a continuous way so that it can be promising for industrial applications. It is confirmed that an Al- 3%Mg-0.2%Sc alloy exhibits superplastic elongation of ~500% at 573K after processing by the CHPT.
