Weight reduction possibility of Al-Li alloys used in air frame structure have studied to describe the effects of various micro-additions towards improvement of traded off property deterioration e.g. toughness, ductility etc. Strengthening to ultra high strengthening have always favored non-shearable precipitation within margins of ductility or toughness in relation to grain formers. Of various micro-additions, La, Cu, Ag, Zn, Ce, V, Li, Zn, Al, Y, (Be+V), (B+Mg), (Ag+Cu) and (Ag+Zr+Mg) have considered in this review. Influence of compositing precipitates those have indigenously developed or dispersoids have studied to report the alloy element activity as the next step towards slip line dispersion and grain boundary pinning to reduce coarsening tendencies. In exogenous particulate addition the composite processing is studied based on SiC, carbon fiber etc. for high temperature application. Metal matrix composites have reported to understand the dual benefits of metal and ceramic properties from a similar system. Interface adhesion, segregation of micro-constituents at interface to reduce strength and respective remedies by reactive element effects have illustrated in interface bond engineering. Metal matrix composite (MMC) of both poly ply and particulates have been indicative to establish strong support towards manufacture of fins and fuselages of aero-sector aluminum engineering.
