چکیده انگلیسی
Reactive spark plasma sintering was performed to synthesize TiB2-AlN-B4C composite at 1650â¯Â°C for 5 min. The results of mechanical tests indicated that the addition of Ti less than 10â¯wt% is beneficial to its mechanical performances. X-ray diffraction and scanning electron microscope (equipped with energy disperse spectroscopy) reveal the reactions between Ti, B4C and AlN to form TiB2 ceramic and laminar Ti-Al-N solid solution that consumes more fracture energy owing to its multilamellar structure and larger aspect ratio. Transmission electron microscope provided an insight into interfacially atomistic structure, surprisingly, two types of diffraction spots were identified as (03¯31)Ti2AlN and (010)AlN, furthermore, their incoherent interphase boundary composed by atomic facets was illustrated.
