Effect of Ultrasonic Mould Vibration on Microstructure & Mechanical Properties of Pure Aluminium Casting During Solidification
Kishor Pawar, Amitesh Kumar
Abstract: The objective of the research is to understand the effect of ultrasonic mould vibration on mechanical properties and microstructure of pure aluminium during solidification. In the present work, effect of ultrasonic vibrations to the mould during solidification of commercially pure aluminium and their effect on microstructure and mechanical properties were studied. Microstructure and mechanical properties were also compared with casting without mould vibration. Grain refinement and increase in mechanical properties obtained due to the ultrasonic vibration of mould. The purity of aluminium sample considered for the research was found to be 96.89 %, and the range of ultrasonic vibration was kept between 20 KHz to 30 KHz. The casting was done in stainless steel mould of thickness less than 0.5 mm. It was found that the ultrasonic mould vibrated casting has fine grain and improvement in mechanical properties as compared to the casting without ultrasonic mould vibration.
