Results reveals that at micro level forged structure was more refined than as in the as cast conditions. This is due to the work hardening effect, where the original structure is destroyed during the forging and recrystallization helped in creating large number of nucleating sites leading to fine grain structure. From the investigations on the mechanical properties, we deduce that the PS, UTS and hardness of forged materials are obviously higher than those of the ones treated with as cast condition without and with the addition of grain refiners and modifier. © 2011 Elsevier B.V.Grain size and shapeMicrostructureRefiningStrain hardeningStructural propertiesA356 alloysAs-castConditionForged a356 alloyGrain modificationsGrains refinementMechanical property and microstructureMicrostructures and mechanical propertiesModificationProperties and microstructuresGrain refinementStudies on the influence of grain refining and modification on microstructure and mechanical properties of forged A356 alloy
