Fast fabrication of Al3Ti/Al composites using combustion synthesis and melt dilution

• Al 3 Ti/Al composites were fast fabricated by combustion synthesis and melt dilution. • Ultrafast heating rate can activate liquid-solid combustion in 5Ti-Al system. • A dissolution-precipitation mechanism for Al 3 Ti formation during CS was established. A simple method combined combustion synthesis (CS) and melt dilution was utilized to fast fabricate Al 3 Ti/Al composites. This paper mainly focuses on analyzing the effect of heat source...
