文摘
- •
Fretting fatigue in Ni-base single-crystal was studied with in-situ SEM experiments.
- •
Formation and evolution of slip lines and microcracks were observed in experiments.
- •
Activations of slip systems in fretting fatigue was studied by CPFEM simulation.
- •
CPFEM simulation agrees with experimental observation in predicting crack formation.
