چکیده انگلیسی
The interfacial behavior of spark plasma sintered ZrB2-SiC nanocomposite doped with graphene nano-platelets was investigated by transmission electron microscopy (TEM). A powder mixture including ZrB2 matrix, 20â¯vol% SiC and 10â¯vol% graphene was used as the starting material. X-ray diffraction analysis did not exhibit any in situ phase formation in the prepared nanocomposite. TEM observations verified the diffusion-controlled sintering. This study clarifies that graphene nano-platelets additive in the prepared nanocomposite did not engage in reactive sintering process, unlike many previous research studies addressing reactive sintering role for carbon additives.
