Effect of Co addition on microstructural and mechanical properties of WC–B4C–SiC composites

Microstructure and mechanical properties of WB2–B4C composites fabricated by boro/carbothermal reduction and SPS

“…In addition, weak B 4 C peak located at 2 θ = 37.8° can be detected. The much weaker diffraction peak intensity of B 4 C phase could be attributed to the great difference between the mass attenuation coefficient values of WB 2 and B 4 C as well as the low mass proportion of B 4 C (16.4% theoretically) in the composite samples 42 . In addition, diffraction peak with relatively low intensity corresponding to WO 3− x phase could be also detected, which suggests residual oxide present in the samples.…”

“…This result could be attributed to the increased heat treatment temperature, which further promotes the theoretically) in the composite samples. 42 In addition, diffraction peak with relatively low intensity corresponding to WO 3−x phase could be also detected, which suggests residual oxide present in the samples.…”

Advanced Boron Carbide Matrix Nanocomposites Obtained from Liquid-Charge: Focused Review

“…The effect of cobalt addition on the microstructure and physical-mechanical properties of SPS WC-B 4 C-SiC composites was studied in [76]. WC-B 4 C-SiC batches containing different amounts of cobalt (10, 15, and 20vol.%) were processed by SPS at 1400 • C. W 2 B 5 and W 3 CoB 3 phases were indicated, as well as free carbon traces and an unreacted silicon carbide phase.…”

Recent progress in B4C–SiC composite ceramics: processing, microstructure, and mechanical properties

“…B 4 C–SiC binary ceramics exhibit better sinterability and mechanical properties than pure B 4 C and SiC ceramics. Recently, the performance of ternary or quaternary systems based on B 4 C–SiC binary ceramics has attracted much attention, such as B 4 C–SiC–TiB 2 , 193–205 B 4 C–SiC–CrB 2 , 206 B 4 C–SiC–NbB 2 , 207 B 4 C–SiC–MoB 2 , 208 B 4 C–SiC–HfB 2 , 209,210 B 4 C–SiC–ZrB 2 , 211,212 B 4 C–SiC–WC, 213 B 4 C–SiC–Al 2 O 3 , 214 B 4 C–SiC–rGO, 215 B 4 C–SiC–carbon nanotubes, 216 B 4 C–SiC–carbon fiber, 217 B 4 C–SiC–Si, 218,219 B 4 C–SiC–Mo, 220 B 4 C–SiC–Al, 221–223 B 4 C–SiC–Al 2 O 3 –MgB 2 , 224 and B 4 C–SiC–Si–TiB 2 . 225 The demand for B 4 C–SiC with good performance promotes further exploration of new materials of ternary or quaternary systems with improved properties based on B 4 C–SiC binary ceramics.…”
