Ultrasonic technology, as an advanced method in materials engineering, has a significant impact on improving casting an‎d alloying processes. By applying high-frequency waves, this technology causes better uniformity in the composition of alloys, favorable distribution of reinforcing particles in composites, removal of gas bubbles an‎d impurities from molten materials, an‎d improvement of mechanical an‎d microstructural properties of materials. With the increasing use of metal-based composites in advanced industries, various methods of manufacturing parts made of these composites have been considered again. One of these methods is the use of high-power ultrasonic technology in the casting process. For this purpose, in the present study, the effect of applying ultrasonic vibrations on the casting of aluminum alloy 6061 (Al6061) an‎d aluminum-based metal composite 6061 reinforced with silicon carbide microparticles (Al6061/SiC) has been investigated.The casting process was carried out in two modes with an‎d without ultrasonic vibrations for the two mentioned materials. Also, the effect of the ultrasonic vibration application time (1 an‎d 2 minutes) on the process output parameters including hardness an‎d compressive strength an‎d grain size an‎d size distribution of SiC reinforcing particles was investigated. At the same time, the effect of reinforcing particles (SiC) an‎d ultrasonic vibrations were also investigated independently in different tests. The results showed that in both base aluminum an‎d aluminum composite samples, the application of ultrasonic vibrations caused the creation of a fine-grained structure in the casting (nearly 48% grain size reduction) an‎d as a result, the hardness (nearly 20% increase in hardness) an‎d compressive strength of the sample increased. Also, in composite samples (Al6061/SiC), the application of ultrasonic vibrations caused a finer an‎d more uniform distribution of SiC particles in the base aluminum material
