The microstructure and tensile property for Al2014 composites reinforced with Ti5Si3-coated SiCP.

The Al2014 composites reinforced with uncoated and Ti 5 Si 3 -coated SiC P were fabricated by stir-casting. The results suggested that the Ti 5 Si 3 -coated SiC P /Al2014 composites exhibited more uniform dispersion of SiC P , higher elastic modulus and tensile properties than uncoated ones. Additionally, the nano-sized Ti 3 AlC 2 interfacial layer was detected between the Ti 5 Si 3 -coated SiC P and α-Al. [ABSTRACT FROM AUTHOR]
