The fabrication and properties of Tip/Al (i.e. aluminum in-situ reinforced with titanium particles, see Figure for its microstructure), a metal-matrix composite with excellent mechanical features, are described. In their plasma jet synthesis of Tip/Al, the Ti wire feed rate, spray optimization, and electromagnetic stirring are identified as crucial for the quality of the material. Due to the different melting points of Ti and Al, the Ti droplets are instantly quenched in the liquid Al.
