摘要： A method of determining fatigue life of metals that are subject to the cyclic load. A metal that exhibits a half-value width that varies depending upon the degree of deformation by fatigue is melt-adhered onto a recessed portion formed in a metal of which the life is to be determined. The two metals are subjected to the cyclic load simultaneously. Then, the melt-adhered metal is irradiated with an X-ray, and a half-value width of an S-N curve of the resulting diffracted X-ray is measured, thereby to determine the fatigue life of the metal of which the life is to be estimated. The method is effective for accurately determining the life even for the metals which exhibit half-value widths that change very little depending upon the degree of deformation by fatigue.
