and automotive industries. The earliest in situ work on Al-TiB2 composites was carried out by the LanxideTM technique [2], followed by the XDTM method [3]. Owing to the proprietary nature of these processes, few details are known apart from some proven work with the above techniques. Recently, a flux assisted in situ fabrication method for the production of TiB2 reinforced Al PRMMCs has emerged[4......
