Abstract
The work is part of researches into the cause of fatigue failure in metals. The effects on the crystalline structure of successive unidirectional tensile strains are compared with the effects of the same strains applied alternately in tension and compression. It is found that X-ray diffraction shows a sharp distinction between the direct and alternating deformation. This is interpreted as showing as a general principle that alternating reversals of a sufficiently small strain do not significantly extend the regions in the grain disturbed by its first application, though they may intensify this local deformation. It is shown that the theory of dislocations could account qualitatively for the localizing of the deformation and the forming of the fatigue crack in the affected regions.
