The interfacial structure and mechanical properties of Ti5Si3-coated SiCP/Al2014 composites fabricated by powder metallurgy with hot pressing

The composites reinforced with Ti5Si3-coated SiCP showed higher relative densities and mechanical properties than those of uncoated ones. It is mainly due to the translation of Ti5Si3 coating layer into Al3Ti interfacial layer during the sintering process, increasing the interfacial bonding strength between α-Al and SiCP.
