Influence of grain size and texture on the flow stress of zinc

The flow stress was measured on rolled, recrystallized zinc with pronounced texture for grain sizes from 0,6 to 502 μm, both parallel and perpendicular to the rolling direction. The results cannot be described by the Hall-Petch relationship. The flow stress exhibits a maximum at a transition grain s...

Description
Summary:The flow stress was measured on rolled, recrystallized zinc with pronounced texture for grain sizes from 0,6 to 502 μm, both parallel and perpendicular to the rolling direction. The results cannot be described by the Hall-Petch relationship. The flow stress exhibits a maximum at a transition grain size. The transition grain size as well as the flow stress depend on the direction of stressing. Differences in the microstructure of the deformed specimens are discussed.
