In order to predict the fatigue life fraction for Al 2024-T3, in-plane bending fatigue test and X-ray diffraction techniques was carried out. The relation between fatigue damage on the specimen surface and half-value breadth of X-ray diffracton lines was investigated in the process of cyclic loading. This paper proposed the estimation of fatigue life using AGM(Average Gradient Method) by the Gradient on the basis of B/Bo and log N/Nf.
