Abstract

In this study, the effect of ultrasonic vibration on mold filling ability, microstructure, and mechanical properties of the aluminum alloy during solidification is investigated. Microstructure and mechanical properties were compared with casting without ultrasonic. Grain refinement and an increase in mechanical properties were obtained due to the ultrasonic vibration. The material used for the research was ADC12 aluminum alloy, and the frequency of ultrasonic vibration was 20 kHz. The casting was carried out in SKD11 steel molds. It was found that the ultrasonic mold vibrated casting has less porosity , fine grain and improvement in mechanical properties as compared to the casting without ultrasonic mold vibration. Where the tensile strength increased by about the tensile strength increased by 20% at 660oC and 9% at 700oC while the hardness changed insignificantly.
