Effect of twins on scratching behavior of nanotwinned diamond: A molecular dynamics simulation
Applied Surface Science(2023)
摘要
•Twins enhance the plasticity of diamond and relieve the stress concentration.•Twins lead to change of the distribution and type of dislocation.•The damage of nanotwinned diamond is caused by amorphization and detwinning.
