- Further information
- This sample was cold rolled. Zinc has a hexagonal structure so it contains only two independent slip systems. However, for slip to occur, five slip systems are required so zinc does not undergo general plasticity. Instead it forms mechanical twins as an alternative to dislocation motion to accommodate the deformation.
