Microstructures and properties of large bulk solidified TiC–TiB2 composites prepared by combustion synthesis under high gravity
چکیده انگلیسی

Large bulk solidified TiC–TiB2 composites with full density were prepared by combustion synthesis in a high-gravity field. The materials presented unique solidification microstructures in which a number of fine TiB2 platelets were embedded in TiC matrix. The hardness, flexural strength and fracture toughness of the materials were 28.5 GPa, 750 ± 25 MPa and 6.2 ± 0.5 MPa m1/2, respectively. The materials’ high hardness resulted from the absence of intermediate borides and the achievement of stoichiometric TiC phases due to rapid solidification.
