Ultrasonication Assisted Fabrication of Aluminum and Magnesium Matrix Nanocomposites - A Review

摘要

Recent researches in the domain of casting confirmed that the mechanical properties of metal based nanocomposites such as Al and Mg can be appreciably enhanced when ultrasonic cavitation assisted solidification processing is used. Ultrasonic vibrations infused solidification technique is used for the manufacturing of aluminum and magnesium alloy metal matrix nanocomposites, with nano sized ceramic particles used as reinforcing agents. In this solidification processing, mitigation of clusters have been observed and the reinforcing agents were dispersed randomly in aluminum and magnesium matrix nanocomposites. The ultrasonic assisted casting approach will manage the grain dimensions via minimizing agglomeration of nano particles in metal matrices. This paper opinions the properties and morphology of aluminum and magnesium based metal matrix nanocomposites fabricated through ultrasonic assisted casting process.
