Abstract
The influence of slip distribution on small fatigue crack growth has been studied in a series of Al–Mg–Si alloys which contain differing volume fractions of dispersoids. Small cracks were found to propagate faster than long cracks when correlated with both ΔK and ΔJ. Although the slip homogenization caused by these dispersoids profoundly effect the behaviour of long cracks no effect on small fatigue crack growth could be detected. Thus the effect of slip distribution on fatigue life is shown to be essentially due to the initiation rather than the propagation of cracks.
