The fatigue gauge is studied as a sensor for determining the magnitude of the stress or the number of the stress cycles of the machine parts subjected to service loading. This gauge utilizes the surface roughness change of the metallic foil, caused by the slip deformathion during cyclic loading. The purpose of this paper is to clear the effect of temperature and cyclic frequency on the surface roughness of the aluminum foil gauge. It is found that the temperature dependence of the stress required to evolve a certain amount of roughness is the same as that of the critical resolved shear stress of the aluminum. Effects of temperature fluctuation and cyclic frequency are not observed. Based on these findings, a method evaluating the applied stress under fluctuating temperature can be Proposed.
