Initiation and Early Growth of FatiguenCracks
Original language description
Experimental evidence concerning the mechanism of initiation and earlyngrowth of short cracks are studied using FESEM, FIB and STEM observations of thensurface of fatigued specimens of several f.c.c.metals. The true shape of persistent slipnmarkings with high resolution is obtained on FIB cuts and using lamella milled on thensurface. Thick extrusions and parallel thin crack-like intrusions are typical featurenbefore crack initiates from the tip of the intrusion. STEM also reveals the relation ofnthe surface relief and internal structure of the material showing in copper ladder-likendislocation structure. The shape of the persistent slip markings is confronted with thenpredictions of the recent theoretical models. Study of the short crack growth and itsnkinetics shows high density of initiated surface cracks and proves the acceleration ofnthe crack growth rate due to linkage of principal crack with initiated surface cracks.nFatigue life is determined by the growth of short cracks and short crack growth lawnis equivalent to the Manson–Coffin law.
