Paper Title:
Microstructures of Co-Continuous SiC/Fe-2Cr13 Composite Fabricated by Vacuum-Pressure Casting and Infiltration Processes
  Abstract

The microstructure of the matrix and the interface of co-continuous SiC/Fe-2Cr13 (porous SiC preforms infiltrated with the Fe-2Cr13) composites has been investigated by XRD, EDS attached to SEM. Results showed that the reaction zone between SiC and Fe-2Cr13 includes two sections, which are silicon carbide reaction zone (SRZ) and metal reaction zone (MRZ), the MRZ can be divided two sections, one is the poor chromium zone (PCrZ-MRZ) and the other is rich chromium zone (RCrZ-MRZ). SRZ is mainly composed of Fe5Si3, Cr7C3, Cr23C6 and Cr3Si, and randomly distributed graphite precipitates. RCrZ-MRZ mainly contains Cr23C6, while PCrZ-MRZ is mostly made up of Fe2Si.
