Interfacial effects in a metallic-glass ribbon reinforced glass-ceramic matrix composite

The effect of temperature on the interfacial effects in a metallic-glass ribbon reinforced glass-ceramic matrix composite was investigated. The metallic-glass ribbon present in this composite was found to be significantly affected at elevated temperatures, owing to the diffusion of lead and zinc from the matrix. The presence of the matrix in the vicinity of the ribbon enhanced the formation of an oxide layer on the ribbon surface. The oxide layer decreased the interfacial bond strength between the ribbon and the matrix, affecting the failure mode of such composites at elevated temperatures.
