Abstract

In this study, the rare earth element Y was added to C_f/Mg composite to improve the interfacial bonding strength. 60vol% C_f/Mg composites containing different Y content were fabricated by pressure infiltration method. An interfacial layer with nano-scale formed between C_f and Mg-Y alloys. The interfacial products were identified to be MgO, Mg₂Y and Mg₂₄Y₅ by energy dispersive X-ray spectroscopy (EDX) and selected area electron diffraction (SAED). Moreover, the interfacial products enhanced the interface bonding strength, which could be confirmed by the increase of interlaminar shear strength (ILSS). In particular, the C_f/Mg composite with 5.7wt% Y addition increases the ILSS by about 120.9% from 46.2MPa to 102.3MPa.
