英语翻译TiB2–SiC ceramic compositeswith different contents of Ni

英语翻译
TiB2–SiC ceramic compositeswith different contents of Ni as additivewere prepared by the ReactiveHot Pressing(RHP) process at 1700 °C under a pressure of 32MPa for 30 min.For comparison,a monolithic TiB2 ceramic and TiB2–SiC ceramic composite were also fabricated under the identical temperature,pressure and holding time by the Hot Pressing (HP) process.The effects of the fabrication process and Ni on the microstructure and mechanical properties of the composites were investigated.About 8vol.% of elongated TiB2 grains with an aspect ratio of 3–6 and a diameter of 0.5–1 μm were produced in the composite prepared by the RHP process.The improvement of the fracture toughness was attributed to the toughening and strengthening effects of SiC particles and the elongated TiB2 grains such as crack deflection.The TiB2–SiC–5 wt.% Ni ceramic composite had the optimum mechanical properties with a flexural strength of 858 ± 87 MPa,fracture toughness of 8.6 ± 0.54 MPa·m1/2 and hardness of 20.2 ± 0.94GPa.The good mechanical properties were ascribed to the relatively fine and homogeneous microstructure and the strengthening effect of Ni.Ni inhibited the anisotropic growth of TiB2.
