| Abstract: | The microstructure and the properties of s147 aluminum alloy plate ateach stage of deformation aging have been studied. The fracture aspects ofthe material have beeu analyzed and examined with a SEM. The microstruct-ures and features of transition phase precipitates of s147 aluminum alloyafter deformation aging have been analyzed and investigated with thin foilSpecimens by TEM. The results Show that the optimun deformation agingCan greatly increase the strength, plasticity and toughness of s147 aluminumalloy, and improve the feature and process of trousition phase precipitates. |
