摘要：
A mechanical surface treatment (deep rolling) was applied at room temperature for the aluminium wrought alloy AA6110-T6 (Al-Mg-Si-Cu). The cyclic deformation behavior and s/n curves of deep rolled AA6110-T6 were investigated by stress-controlled fatigue tests at elevated temperatures up to 250 degrees C and compared to the polished condition as a reference. The effect of deep rolling on the fatigue lifetime and residual stresses under high-loading and/or elevated-temperature conditions are discussed. (c) 2006 Acta Materialia Inc.
