文摘
- •
The nanoindentation of L12-ordered Ni3Al was simulated by molecular dynamics.
- •
Indentation-induced dislocation mechanisms were discussed comprehensively.
- •
Pop-in events stem from dislocation generation, multiplication and reactions.
- •
Present benchmarks for evaluating the credibility of interatomic potentials.
- •
Provide further insights for understanding incipient plasticity at atomic level.
