摘要：
For the purposes of iron analysis, the focused ion beam was used to obtain cross-sections of fracture surfaces in FeAl-WC and FeAl-TiC composites. On comparing debonded regions of the two composites, a greater extent of debonding was observed in FeAl-TiC, on the order of the particle size. The FeAl-WC exhibited less debonding, and a greater degree of plastic deformation in the matrix. These results suggest weaker interfacial bonding in the FeAl-TiC.
