%X The microstructure and deformation mechanisms in cyclic stress were studiedfor an Al-Mg-Si alloy 6063 treated with different aging conditions.A discussion in con-nection with fatigue properties and fracture mode of the alloy was performed.The resultsshow that the aging condition has considerable influence on the microstructure anddeformation mechanisms.In the UA and PA conditions which had GP zones,thedeformation was carried out in the cut off mode,the heterogeneous planar slip bands wereformed.In the OA condition which had precipitates,the dislocations were bowed out andthe homogeneous dislocation tangles were formed.The deformation behavior has consider-able effect on the fatigue fracture mode.
