    Abstract

    The fatigue characteristics of cast magnesium, as determined both from laboratory tests and service experience, are discussed. These pertain to the relative importance of mechanical surface condition, design, surface and subsurface metallurgy, and residual stresses. Such factors as surface condition and design are shown to have so great an influence as to render fatigue data from polished test bars of limited quantitative use. Subsurface metallurgy and residual stresses, on the other hand, are factors which are of but minor importance in magnesium castings.
