Abstract
It is well known that ferrous metals have distinct fatigue limits while most nonferrous metals do not and that the notch sensitivity in fatigue is different from metal to metal. For example, Al-alloy is more sensitive than low carbon steels[1][2]. These two phenomena seem to be independent. However, they are closely related to each other; that is, both phenomena are correlated by the behavior of microcracks initiated from surfaces.
