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

The Al2014 composites reinforced with uncoated and Ti5Si3-coated SiCP were fabricated by stir-casting. The results suggested that the Ti5Si3-coated SiCP/Al2014 composites exhibited more uniform dispersion of SiCP, higher elastic modulus and tensile properties than uncoated ones. Additionally, the nano-sized Ti3AlC2 interfacial layer was detected between the Ti5Si3-coated SiCP and α-Al.
