Abstract

Microfractographic aspects of fatigue fracturing were examined in relation to the strength level of material and the macrocrack propagation rate, da/dN, with particular emphasis on the low da/dN range. The materials investigated were heat-treated carbon and low alloy steels characterized by different levels of Vickers hardness. Fatigue tests were conducted under repeated tensile loads. For low da/dN values the fatigue fractue surface exhibited a certain amount of intergranular facets.
