Description
Summary:Mechanical properties and microstructural evolution of Cu-10wt.%Zn and Cu-30wt.%Zn alloys after pre-torsional deformation have been investigated in this study. The results indicated that pre-torsional deformation can significantly enhance the strength of both Cu-10wt.%Zn and Cu-30wt.%Zn alloys without changing their shape and size, but with the sacrifice of the ductility. The pre-torsion deformation can introduce gradient hardness and microstructures along the radial direction, with the microstructures along the radial direction in Cu-30wt.%Zn alloy being "dislocations→stacking faults→twins (low density)". The stacking fault energy affects significantly the microstructure along the radial direction.
