... different site ( Ref 5 ). Under these conditions, the stress required for deformation to continue rises very slowly with strain; hence, this stage of deformation is called easy glide. Under suitable circumstances, the whole stress-strain curve of a hexagonal crystal consists of the easy glide region. This...
