Achievement of uniform grains with weakened basal texture via dynamic recrystallization and twin during cross-rolling in ZK60 alloy and corresponding mechanical properties

In this work, the ZK60 sheets were prepared via multi-pass unidirectional rolling and multi-pass cross-rolling. In comparison with the unidirectional rolled sample, the cross-rolled sample exhibits a uniform grain distribution and a weakened basal texture. The primary factors are as follows: (I) the volume fraction of dynamically recrystallized grains in the CR sample exceeds that in the UR sample; (II) the continuous dynamic recrystallization (CDRX) is the dominant DRX mode in the CR sample; (III) the grain orientation can be altered through twinning in the CR sample. The mechanical properties of the CR sample show slight improvement.
