The aim of the present paper is to review the recent progress in the synthesis of in situ particle reinforced aluminum composites using thermal, mechanical and combined mechanical-thermal activation of aluminothermic reduction reactions. The combination of combustion synthesis (CS) and mechanosynthesis (MS) is the most recent development in the processing of advanced materials like micro and nano aluminum based composites. The combined mechanical thermal synthesis (MTS) has widened the possibilities for both CS and MS. MTS holds great potential for commercial viability and offers exciting processing route for the synthesis of advanced materials. Enhanced reaction kinetics and extended concentration limits in MTS are demonstrated by illustrating the synthesis of aluminum based nanocomposite involving Al–CeO2.

Magnesium based surface metal matrix composites by friction stir processing

A TiB 2 particulate reinforced magnesium matrix composite (MMCs) was fabricated by adding a TiB 2 –Al master alloy processed via self-propagating high-temperature synthesis (SHS) reaction in Al–Ti–B system into molten magnesium and using the stir casting technique. The results showed that the TiB 2 –Al master alloy and TiB 2 /Mg composite contained a certain amount of transient TiAl 3 phase. When the Al–Ti–B system was incorporated with an appropriate C, TiB 2 and TiC reinforcing phases were simultaneously synthesized and the TiAl 3 phase was almost completely eliminated.
