Abstract A study was made on the fatigue fracture behaviour under different aging cond-itions of two Al-Mg-Si alloys with different chemical composition and dispersoid contents.The dispersoid phase can alter the mode of fatigue fracture by the influence on the deformationuniformity of alloy. The dispersoid itself may decohere from the dispersoid/matrix interface undercyclic fatigue stress to form small-sized dimples.

Key words: Al-Mg-Si alloy dispersoid fatigue fracture
