Summary: This study aimed to consolidate zirconium diboride-reinforced composites using the SPS technique, investigating the effects of different powder mixture preparation methods, reinforcing phase content, and sintering temperature on the properties of the composites. It was found that milling in a planetary mill improved the dispersion of ZrB2 particles in the steel matrix, while higher ZrB2 content resulted in enhanced hardness and wear resistance of the composites.

Summary: In recent years, there has been renewed research interest in AlB2-type layered metal diborides due to their ability to yield XBenes. In this work, a scalable approach using high-energy ball milling is presented to exfoliate titanium diboride (TiB2) into multi-layer-thick nanosheets. The exfoliated TiB2 nanosheets retain their chemical integrity to a large extent and exhibit enhanced electrochemical activity.

Summary: Square-shaped monolithic B4C and B4C-ZrB2 composites were produced using SPS method. The addition of 5, 10, 15 vol% ZrB2 had an effect on the densification, mechanical and microstructural properties of boron carbide. The density of B4C increased with increasing volume fraction of ZrB2 and the density differences in different regions of the sample decreased. The addition of ZrB2 enhanced the hardness and fracture toughness of the composites compared to monolithic B4C. The B4C-15 vol% ZrB2 composite exhibited superior properties with a hardness of 33.08 GPa and Vickers indentation fracture toughness of 3.82 MPa·m1/2.

Summary: The study focuses on preparing Mo-10 vol%La2O3 and Mo-10 vol% La2Zr2O7 composite powders via low- and high-energy ball milling, with the high-energy mode resulting in more homogenous powder agglomerates and uniform ceramic phase distribution. The Mo-10 vol% La2Zr2O7 composite powder exhibits better thermal stability and less formation of intermediate phases compared to Mo-La2O3 composite powder, making it a promising material for high-temperature applications.

Summary: This study aimed to improve the productivity of nanobiochar (NBC) through high-energy ball milling, finding that using grinding media with different sizes of steel balls was more effective. Results showed that 30 minutes of ball milling could produce NBC particles around 95 nm, while 60 minutes were sufficient to produce 75 nm NBC particles with high thermal stability.

Summary: Zirconium diboride ceramics with carbon and boron carbide nanopowder additives were prepared by ball milling and pressureless sintering. The addition of nano-B4C and C had significant effects on the density and grain size of the materials. The use of different grinding media also resulted in different outcomes.

Summary: In this study, the wettability of diborides in contact with a filler layer was evaluated using a powder-based approach. The results showed that surface roughness affects the spreading of molten Ni on the diboride surface, and the addition of hydrogen gas improves the wettability. Successful brazing of the diboride composites with a Ni interlayer resulted in microstructural inhomogeneity, but the lower interfacial residual stresses provided structural integrity between the ceramic and metal layers.

Summary: Research has shown that pure SnSe polycrystalline materials prepared by high-energy ball milling exhibit a high ZT value at 873K. The decrease in lattice thermal conductivity and increase in Sn vacancies induced by high-energy ball milling contribute to the improved conductivity of the materials. The absence of oxidation during the ball milling process in a closed argon-filled environment ensures the purity of the SnSe polycrystalline materials, leading to their high ZT value.

Summary: This study reports the process to fabricate powder of high-entropy carbide (TiTaNbZrHf)C using two-step high-energy ball milling. The high-entropy carbide phase was obtained through milling metallic precursors and carbon, showing thermal stability up to 1200 degrees C. The process includes the conversion of metallic precursors, the reaction diffusion of carbon, and the formation of high-entropy carbide phase from high-entropy alloy and carbon.

Summary: This study presents the effect of zirconium diboride (ZrB2) and titanium diboride (TiB2) on the microstructure and physical, mechanical, and tribological properties of composites based on 316 L steel. The amount of each reinforcing phase added to the base alloy was 5 wt% and 10 wt%. The composites were fabricated using the SPS process. The results demonstrate that the weight fraction of the reinforcing phase influences the physical, mechanical, and tribological properties of the sintered composites. The addition of TiB2 effectively increases the hardness and compressive strength of the composites, while introducing ZrB2 improves the wear resistance of the composites.
