A Review on the Development of Processing Techniques for the Production and Casting of Al-Alloy and Metal Matrix Composite Material

Liquid metallurgy is a cost-effective way to produce aluminium (Al) alloy products. Alloying and reinforcing in aluminium-matrix is the most practiced one in the liquid metallurgical technique, especially for mass production. Numerous developments have been observed in this technique over the past decade. This paper reviews most of the developments in processing techniques, along with providing basic information and parameters. Also, the shortcomings of each process have been significantly summarized, and potential research opportunities have been discussed. The developments in the batch and mass liquid metallurgical technique for Al have been discussed. The latest development recommendation for processing parameters and techniques to reduce the cost and time of production has been studied in detail. Based on the literature review and various published patents, the most relevant technique is a bottom-feeding continuous casting technique to produce metal matrix composites and aluminium alloys.
