- •
Low-stress cyclic loading can achieve mechanical healing with little shape change.
- •
Junction failure mechanisms under monotonic and cyclic loadings are revealed.
- •
Cumulative irreversible slip promotes dislocation annihilation and junction failure.
- •
Theoretical model is built to predict the critical condition of mechanical annealing.
