摘要：

The　18R　and　14H　long-period　stacking　ordered　(LPSO)　phases　were　generally　considered　that　only　the　basal　and　non-basal　a　c+a　c+a　c+a　slips　are　localized　in　the　well-defined　slip　bands　while　the　chemically　ordered　structure　of　Zn6Y8　atomic　clusters　is　disrupted　to　be　disordered.　Additionally,　the　interaction　also　induces　Zn/Y　atoms　segregation　at　the　two　edges　of　the　slip　band.　Our　results　unravel　the　origin　for　the　excellent　room　temperature　plasticity　in　the　LPSO　phases.
