- •
Hydrostatic extrusion integrated with circular ECAP was proposed.
- •
High properties AZ80 Mg alloy tube was prepared by HECCAP.
- •
Small diameter billet could be extruded into tube of larger diameter using the method.
- •
UTS, TYS and EP of the tubes were 335 MPa, 308 MPa, and 7.2%, respectively.
- •
A formula was proposed to calculate the total generated plastic strain for HECCAP.
