文摘
- •
MD simulations of indentation are performed to uncover deformation mechanism in VN.
- •
The dislocation flower and four kinds of dislocation loops are observed in VN.
- •
The evolution of partial dislocations is the main mechanism in VN at initial stage.
- •
The formation of the dislocation flower and dislocation loops are analyzed.
