摘要: Abstract Microstructure and mechanical properties of the forged A356 alloy have been investigated in this paper. Results reveals that at micro level structure was more refined than as cast conditions. This is due to work hardening effect, where original destroyed during forging recrystallization helped creating large number nucleating sites leading fine grain structure. From investigations on properties, we deduce PS, UTS hardness materials are obviously higher those ones treated with condition without addition refiners modifier.
