Abstract: Tension-compression fatigue test was performed to study the effect of the cold working + ageing treatment on the fatigue property of Al-Li alloy under stress-controlled condition. The main results show that: fatigue strength of specimen is improved obviously after cold working + ageing treatment; compared to the simple ageing treatment, the necessary ageing time can be reduced apparently to reach the peak-ageing strengthening effect; the fatigue strength of specimen cut from the vertical direction to cold working direction is higher than that cut from the parallel direction.
