摘要：

In this study, the carbon-rich coated silicon carbide (SiC) fiber-reinforced Ti3AlC2 matrix composites having two distinct fiber concentrations had been prepared by hot-pressing at 1250 degrees C and 1300 degrees C, respectively. Interfacial reaction layer between the fiber and the matrix was characterized by using field emission scanning electron microscopy (FE-SEM). Elemental distribution maps of the interfacial reaction layer were quantitatively examined by energy-dispersive spectroscopy (EDS). The effects of processing temperature on the interfacial reaction layer formed during hot-pressing were assessed. In addition, the flexural strength and fracture behavior of the resulting composites depended on the processing temperatures as well as on the fiber volume fraction. Noncatastrophic fracture behavior was observed only for 15 vol% SiC fiber-containing composite processed at 1250 degrees C. (C) 2014 Elsevier Ltd. All rights reserved.
