- •
Intercrystalline crack propagation of nano-nickel bicrystal film is investigated.
- •
Plasticity of nano-nickel bicrystal film decreases with increasing twist angle.
- •
Fracture mode of the nano-nickel bicrystal film is affected by the twist angle.
- •
Mechanism of three typical fracture modes was revealed clearly.
