抄録

In the previous papers, the authors reported that the half-value breadths of metals read from X-ray diffraction lines changed with application of alternating stresses at a constant or varying stress amplitude. It was found that the b/B -log n/N (n/N is a cycle ratio) or the b/B - log Σ n/N (Σ n/N is the summation of cycle ratios under a varying stress amplitude) relations were expressed by straight line, and offered a certain method of nondestructive prediction of fatigue life. On the other hand, in order to interpret the change in half-value breadth due to stress repetitions, we investigated the appearance of slip-bands that developed on the surface of the annealed carbon steel, and also observed the change in macro-residual stress in fatigue processes. In the present investigation, we investigated the relation between change in half-value breadth and macro-residual stress, micro-structure, micro-hardness of cold worked carbon steel and age hardenable Al-Cu alloy, and discussed on the change in half-value breadth from the standpoint of the fatigue mechanism.
