Part I: Wöhler curves and fractured surfaces	2016	9	.pdf	application/pdf	3658	201	51	Surface short fatigue cracks are observed from origin to fracture by using acetate-foil replication technique, and their length, a, measured at the corresponding number of fatigue cycles, N. Those data are presented in plots “Crack lengths, a – Cycles, N” and a comparison made between both the steels. The observed cracks interaction on the fractured surface of Specimen 7 also can be indirectly confirmed by replica monitoring of surface propagation of short fatigue cracks, Fig.	cache/fis-1744.pdf	txt/fis-1744.txt
