Particulate Based AZ91 Magnesium Hybrid Composites – A Short Review

The present paper deals with the study of magnesium alloy hybrid composites. AZ91 is a popular magnesium alloy with good specific strength at room temperatures. However, it suffers with poor mechanical properties at elevated temperatures. The reinforcement materials can be prepared by polymers and ceramic particles. The selection of proper material will have a greater response on the properties. Therefore, in order to increase the mechanical responses, preparation of composites is good idea with low cost. To ensure multiple properties, it is always necessary to go with Hybrid composites. In this context, this paper reviews the materials used in the fabrication of composites, fabrication Techniques, microscopic behaviours and mechanical responses. This paper also provides research potentials along with the latest developments in the area of AZ91 Composites.
