Summary: The addition of Ti and its compounds to B4C ceramics has been found to enhance fracture toughness, densification characteristics, and mechanical properties. Among the different Ti-based compounds, TiC showed the most optimal mechanical properties in terms of fracture toughness, flexural strength, hardness, and elastic modulus in the B4C-TiB2 multiphase ceramics.

Summary: Different amounts of TiC particles were coated on B4C granules, forming in-situ TiB2 network structures to improve the thermoelectric performance of B4C. The maximum achieved ZT value was 8.02x10-2, approximately 120% higher than that of pure B4C. However, higher quantities of TiC addition did not effectively enhance the thermoelectric performance.

Summary: High-entropy ceramics and their composites have excellent properties, but their unique characteristics make it difficult to sinter them. This study presents a rapid liquid phase-assisted ultrahigh-temperature sintering strategy, successfully preparing a high-entropy metal diboride/boron carbide composite with high hardness.

Summary: This study investigates the influence of increasing the milling time on boron carbide sintering using a high-energetic rotaryvibratory mill and WC-Co balls. The content of tungsten boride phase increases with prolonged milling time, affecting the onset and end process temperature of sintering. The impact of WC contamination on boron carbide laser sintering process was also analyzed.

Summary: This study focuses on the effect of adding boron, titanium, and a mixture of both on boron carbide (B4C) based composites. The presence and distribution of the additives in the sintered composites are confirmed through X-ray diffraction and scanning electron microscopy (SEM). Mechanical properties, density, and porosity of the composites are tested and show high values. The usage of a boron and titanium mixture significantly improves the sintering process, leading to the classification of the Ti-B4C composites as ultrahigh-temperature ceramics materials.

Summary: Lightweight polycrystalline ceramics have promising physical, chemical, and mechanical properties. However, their coarse-grained structures make them brittle and low in fracture toughness. It has been discovered that nanocrystalline ceramics with soft interface phases or disordered structures can significantly enhance their mechanical properties.

Summary: This study investigated the effects of B4C content on the specific stiffness, mechanical properties, and thermal properties of pressureless-sintered SiC ceramics. SiC ceramics with 2.5 wt% C and 0.7-20 wt% B4C as sintering aids were successfully sintered to over 99.4% of theoretical density at 2150 degrees C in Ar. The specific stiffness of SiC ceramics increased from 136.1 x 106 to 144.4 x 106 m2 & BULL;s- 2 as the B4C content increased from 0.7 to 20 wt%.

Summary: Boron carbide is a material with high thermoelectric power that can be used in thermoelectric applications. In this study, boron carbide and hafnium boride composites were prepared by pressureless sintering of B4C and HfC powders, and the effect of HfC addition on the sinterability and thermoelectric properties was investigated. The results showed that the addition of HfC decreased the Seebeck coefficient and increased the electrical conductivity, leading to a change in conduction behavior from semiconducting to metallic mechanism. The functional thermocouples based on the prepared composites showed potential for temperature measurement applications.

Summary: This review compares the most commonly used ballistic ceramics, including alumina, silicon carbide, and boron carbide, in terms of various performance mechanisms. It aims to study the mechanical properties of ceramics and their role in dynamic ballistic performance to address the controversy in the literature. The study found that silicon carbide performs best against 7.62 AP projectiles, with hardness and flexural strength correlated to ceramics' performance in depth of penetration tests, demonstrating the dependence of ceramics' ballistic performance on multiple properties.

Summary: A strategy of incorporating B4C to improve the specific stiffness of SiC ceramics was developed. The incorporation of B4C effectively increased the specific stiffness of SiC ceramics as B4C has a lower mass density and higher Young's modulus. B4C also served as an effective additive for sintering SiC ceramics.

Summary: The mechanical properties of BAM-B4C composite materials improve with the addition of B4C, but excessive addition can lead to phase segregation and cracking, thus degrading the mechanical properties of the composite.

Summary: This study synthesized B4C and SiC nanoparticles to prepare ultrafine-grained B4C-SiC ceramics and systematically investigated the effect of grain size on the mechanical properties of the composites. It was found that residual stress emerged in the B4C-SiC interface as B4C grains reached a nanostructured state, improving the toughness significantly to 5.13 MPa m1/2. The B4C-SiC composite also exhibited excellent hardness of 36.6 GPa, surpassing that of monolithic B4C ceramics. This study has important implications for the development of toughening mechanisms for B4C-SiC ceramics and presents a new strategy for producing high-performance ceramics.

Summary: In this study, a B4C-TiB2 composite was synthesized by in situ reaction, exhibiting improved hardness, bending strength, and fracture toughness compared to B4C monolith. The presence of TiB2 in B4C matrix and the smaller grain size contributed to the enhancements in mechanical properties.

Summary: The research investigates the corrosion behavior of dense ZrB2-based ceramic samples in simulated seawater using polarization curves of electrochemical oxidation (ECO). The addition of AlN was found to promote the formation of a stable protective film, leading to higher values of E-a and i(corr) in ECO conditions for ZrB2-SiC materials.
