In order to study the high-temperature flow stress of commercial purity aluminum (AA1070),
isothermal hot compression tests were conducted at the deformation temperatures varying …

In order to improve the mechanical properties of profiles extruded from aluminum chips, a
four turn equal channel angular pressing tool was integrated into an extrusion die (iECAP …

A new severe plastic deformation (SPD) method entitled Tube Channel Pressing (TCP) is
proposed. In this study, the ability of TCP on strength improvement and grain refinement is …

The direct conversion of aluminum alloy machining chips into finished parts by hot extrusion
with subsequent cold extrusion was investigated. While the process of hot extrusion was …

A new phenomenological and empirically-based constitutive model was proposed to modify
the term in the original Johnson–Cook constitutive model. The new model can be used to …

Electrical conductivity is important for the applications of metals containing nanoparticles,
