Tuning of nanostructure by the control of twin density, dislocation density, crystallite size, and stacking fault energy in Cu 100−x Zn x (0≤ x ≤30 wt%)

The present study demonstrate the effect of stacking fault energy (SFE) on the evolution of crystallite size, dislocation density, twin density, stacking faults, and their mutual interactions during cryorolling in pure copper (SFE 78 mJ/m2) and copper–zinc alloys with varying Zn content of 10 wt% (SFE 35 mJ/m2), 20 wt% (SFE 19 mJ/m2), and 30 wt% (SFE 14 mJ/m2). The dislocation density, twin density and extrinsic fault probability increase...
