Effects of Initial Texture on the Formation of Deformation Twins in a Cu–Zn System Alloy

Heavily and simply cold-rolled Cu alloys with ultra-low stacking fault energy exhibit superior strength/ductility balance. The excellent mechanical properties are attained by the formation of a heterogeneous-nano (HN) structure consisting twin domains, shear bands, lamellar grains. In this study, using Cu–Zn system alloy, two specimens different initial textures were subjected to cold rolling. One has strong 〈001〉 texture along normal direction (ND) rolling surface, other 〈111〉 texture. Then, effects on deformation twins in early stage precisely investigated. Also, microstructure finally developed HN after 90%-cold-rolling examined. At rolling, twinning occurred more frequently specimen than one. difference frequency can be reasonably explained significant ratio Schmid factor for partial one perfect dislocation. On 90% exhibited better balance that since higher volume fraction domains. It concluded before plays an important role structured materials via
