Abstract：
Dynamic strain Aging pre-treatment processes increase remarkably the fatigue strength. the strenthening effects increase with increasing prestrain temperature and prestrain. TEM shows that uniform and stable dislocation networks with high density form after DSA pre-treatment. These networks suppress effectively the initiation and propagation of fatigue cracks and increase the fatigue strength.
