چکیده انگلیسی
In this study, flexural strength measurements and microstructural studies have been combined to evaluate the effect of elevated temperatures on the fracture behavior of B4C-TaB2 ceramic composites that have a eutectic structure. Mechanical characterization was carried out at 1600 °C, 1800 °C and 2000 °C. The B4C-TaB2 eutectic composites were prepared in situ using a spark plasma sintering technique. The eutectic composites exhibited strengths of 483±17 MPa and 525±12 MPa at 1600 °C and 1800 °C, respectively, which is higher than the strength of 430±25 MPa measured at room temperature. The flexural strength of the B4C-TaB2 eutectic composites was 511±16 MPa at 2000 °C (i.e. 0.86 of the melting point of the B4C-TaB2 eutectic), indicating plastic behavior. Analyses of the high-temperature flexural strength behavior of this non-oxide eutectic are reported.
