Abstract
We analyze the well-known works devoted to the adsorption lowering of crack growth resistance in metals and alloys as a component of the general Karpenko theory on the role of adsorption in physicochemical fracture mechanics. We consider the cases of static and cyclic loading, and short- and long-term crack resistance of steels in liquid and gaseous media. Special attention is given to the methodological aspects of experimental investigations and to the selection of model adsorption-surface-active media. We also evaluate the crucial experiment corroborating the adsorption effect of lowering of the long-term static crack resistance of high-strength steel in high-purity dimethylsulfoxide.
