This paper provides a review of the research that has led to our current understanding
of the process of fatigue striation formation. An important question addressed is whether or not at low
stress intensity values, fatigue cracks can propagate intermittently in steels and aluminum alloys. It is
concluded that there is no valid evidence for propagation on other than a cycle-by-cycle basis.
