Amorphous and glassy alloys have excellent mechanical properties, which are high tensile strength,high elastic limit,low elastic modulus and high ductility.Therefore,the alloys are expected for practical high-strength structural materials.However,there were the reports that the alloys show remarkably smaller fatigue strength than the crystal alloys.In this report, the data of fatigue limit in the literature were reviewed and compared with those on the crystalline alloys.Some amorphous and glassy alloys showed the fatigue ratios which are almost same or a little smaller than those on the Al alloys representative of the non-iron crystal alloy.The nanocrystal dispersion to the glassy phase increased the fatigue limit.This indicates that fatigue characteristics of the glassy alloys have the possibilities of the improvement
