Abstract Casting is one of the oldest and mostly used production methods in industry. The traditional casting has certain disadvantages like poor strength due to hot tears, shrinkage and poor surface finish. The properties of casted product mostly depend on the microstructure after solidification. Providing Mould vibration during casting is one of the latest techniques employed in order to get better structure in the solidified casting. Mould vibration during casting gives reduced amount of shrinkage, better morphology, surface finish, and less chances of hot tear. In this research work the effect of mould vibration on casting during solidification of Al-6063 alloys for different values of wave lengths at fixed pouring temperatures is investigated to understand the changes in microstructure and mechanical properties of casting .The casting has been prepared in iron EN8 mould with and without vibrations. The frequencies varied from 0Hz to 40 Hz. A casting has been made without vibration as well to compare the results of castings with vibration. The experimental results showed significant grain refinement and remarkably improvement in mechanical properties of casting with mechanical mould vibration during solidification.

INTRODUCTION Now a day’s more than 85% of products are produced by casting processes. The totality of metal s and alloys begin to work by a very important operation, that of solidification. Solidification is the operation that gives shape and structure. Currently the solidification technique has experienced a rapid development. Because of progresses made as yet the castings are used in high security parts in the aero-spatial industry, the automotive, chemical and metallurgical equipment [1]. Recent techniques suggest that, mold vibration during pouring and till solidification is one of the important methods to produce casting for better morphology, surface finish and reduced amount of shrinkage [2]. Mold conditions, pouring temperature, frequency of vibration and other process variables are factors that would have a definite effect on the microstructure and properties of the cast [3]. Investigated the mechanical vibration causes improvement in mechanical and corrosion properties of alloys. The mechanical mold vibration on liquid metallic materials and their crystallization has a significant effect on the grain structure of the casting, grain size reduced by vibration and grain became more compact.
