摘要:The current work investigated the influence of aging treatment on fatigue crack growth behavior of eutectic Sn-Pb alloy. After aging treatment, the eutectic grain structure changed to particle structure. This seriously influenced the time-dependent fatigue crack growth behavior, as well as the cyclic dependent behavior resistance in near-threshold regime at high frequency, while having slight influence on the crack propagation in Paris regime.
