Microstructural evolution and mechanical properties of a Cu-Zr alloy processed by high-pressure torsion

- A Cu-0.1% Zr alloy was processed by HPT for up to 10 turns.
- The hardness and microstructure both evolve with increasing torsional strain.
- There is a high degree of homogeneity after 5 and 10 turns.
- A maximum tensile elongation of 280% was recorded in testing at 723 K.
