“…Our previous works have demonstrated that the additives such as LaB 6 [10], C f [11], SiC f [12], Al 4 SiC 4 [13], and graphene [14], etc., are potential candidates for improving the fracture toughness. Besides these additives, MWCNTs have been confirmed as one of the most promising reinforcements in oxides [15,16], carbides [17,18], nitrides [19,20], and borides [21,22]. The well-known strengthening and toughening mechanisms are "crack bridging", "pull-out", and "crack deflection".…”

Multi-walled carbon nanotubes (MWCNTs) reinforced Si 2 BC 3 N ceramics were prepared through mechanical alloying (MA) and following spark plasma sintering (SPS). The thermal shock resistance of Si 2 BC 3 N ceramics was evaluated comparatively through ice water quenching test and theoretical prediction. Furthermore, the oxidation resistance of MWCNTs incorporated Si 2 BC 3 N ceramics was evaluated under high temperature. The results show that the calculated parameters such as the critical thermal shock temperature (R) and the thermal stresses resistance (R st ), as well as the toughness (R) are improved with addition of 1 vol% MWCNTs. In addition, the crack propagation resistance of 1 vol% MWCNTs incorporated Si 2 BC 3 N ceramics is obviously improved through generating more tortuous crack propagation paths attributing to the "crack bridging", "pull-out", and "crack deflection" mechanisms of MWCNTs. Therefore, the residual strengths of 1 vol% MWCNTs containing specimens remained the highest after the thermal shock tests. Besides, the present work also reveals that the oxidation resistance is more sensitive to relative density than MWCNTs addition. a next generation of sharp re-entry space vehicles [1]. Up to date, the intensively investigated HTCs are mainly composed of binary (e.g., SiC, Si 3 N 4 , and ZrB 2 ), ternary (SiCN), and quaternary (including SiBCN and SiCNTi) composites [2][3][4]. In the last decade, we have successfully prepared bulk SiBCN ceramics through MA and subsequently HP/SPS sintering. With preparing bulk SiBCN ceramics, the measurements of properties such as flexural strength, fracture toughness, and thermal shock resistance became feasible [5][6][7][8][9].

“…The fracture toughness and work of fracture for PyC–C f /ZrC–SiC are 5.37 ± 0.25 MPa∙m 1/2 and 951 ± 12 J/m 2 , 50% and nearly order of magnitude higher than those of ZrC–SiC composite, respectively. Exceptionally, the work of fracture is much larger than the values of other UHTCs matrix composites with rivaling flexural strength simultaneously (see in Figure A,B), which tackles the dilemma between toughness and strength . Figure shows the load‐displacement curves of PyC–C f /ZrC–SiC and ZrC–SiC.…”

Inspired by grouting technique in architectural engineering, an innovative method of slurry injection and vacuum impregnation was put forward to introduce nanosized ZrC-SiC ceramics into PyC modified 3-D needle-punched carbon fiber preform homogeneously and continuously, followed by spark plasma sintering to prepare C f /ZrC-SiC with graceful mechanical responses. The composite possessed improved fracture toughness and work of fracture at 5.37 ± 0.25 MPa•m 1/2 and 951 ± 12 J/m 2 , 50% and nearly one order of magnitude higher than those of ZrC-SiC composite, respectively, with rivaling flexural strength at 177 ± 8 MPa synchronously. A graceful fracture mode was embodied in an obviously extended yield plateau with increased failure displacement by 300%. This enhancement was attributed to the uniform and continuous combination of ZrC-SiC with carbon fiber preform as well as protection and interface tailoring from PyC coating. The study offered an easy and effective method of preparing 3-D fiber reinforced ceramic matrix composites. K E Y W O R D Sarchitectural engineering, carbon fiber, PyC, slurry injection

The high-performance tool materials have been inevitably used for most of the cutting tool applications where high reliability and difficult to cut materials are of major demand. The cemented carbides and its composites offer an excellent combination of the properties where it can be used for tool materials due to its high wear resistance, high hardness at elevated temperatures, and considerable fracture toughness. However to obtain optimum values of mechanical properties and uniformly distributed ultrafine grains, a number of new fabrication techniques, alteration in the content of cemented carbide composition, and variation in the parameters of fabrication process have been employed. This review paper will come in handy for researchers and scientists working on advanced cemented carbides and spark plasma sintering as it overviews the recent work done on tungsten carbide composites using the novel spark plasma sintering technique considering different process parameters in order to achieve ultrafine microstructures of sintered specimens, enhanced mechanical properties of composites in addition to energy as well as time saving considerations. The thorough review of various research papers revealed that the parameters of the sintering (sintering temperature, applied pressure, surrounding environment), additives in sintering (both content and composition), reinforcement of cemented carbide with other materials, nano-filler/whisker addition, partial or complete removal of metallic phase from the cemented carbide affect the properties of sintered specimens and their calculated as well as optimum setting can provide an excellent combination of properties desired in cutting tool operations.
