Abstract : The fatigue resistance of some metals may be improved by understressing followed by a process of gradually increasing the amplitude of the alternating stress in small increments, a procedure ordinarily called 'coaxing.' In the present paper a study is made of the effect of various coaxing procedures on the fatigue resistance of ingot iron, SAE 1045 and 2340 steels, 75S-T6 aluminum alloy and annealed 70-30 brass. The results of this study seem to indicate that the coaxing effect in fatigue is governed by a time-dependent localized strengthening through strain-aging and not by the ability of the metal to be strengthened by cold work.
