Abstract
In situ method of synthesizing aluminum matrix composites (AMCs) has been widely
recognized and followed by researchers due to numerous merits over conventional stir
casting. Aluminum alloy AA6061 reinforced with various amounts (0, 2.5 and 5 wt. %) of
TiC particles were synthesized by the in situ reaction of inorganic salt K2TiF6 and ceramic
particle SiC with molten aluminum. The casting was carried out at an elevated temperature
and held for a longer duration to decompose SiC to release carbon atoms. X-ray diffraction
patterns of the prepared AMCs clearly revealed the formation of TiC particles without the
occurrence of any other intermetallic compounds. The microstructure of the prepared
AA6061/TiC AMCs was studied using field emission scanning electron microscope…
