The microstructure and mechanical properties of the samples at different distances from the acoustic radiator were characterized for 650 degrees C pouring temperature. The combined technique lead to cast samples free from gas porosities and solidification defects, promoted the formation of small alpha-Al globular grains, modified the eutectic silicon, dispersed and decreased the size of intermetallic phases. The alloy mechanical properties were improved, increasing the ultimate tensile strength, yield strength and strain.This work is supported by FCT with the reference project UID/EEA/04436/2013, by FEDER funds through the COMPETE 2020 - Programa Operacional Competitividade e Internacionalização (POCI) with the reference project POCI-01-0145-FEDER-006941.
