“…For the λ(∆g, n) mode, processing factors that have been studied include different carbide size [68,69], different binder phases [70][71][72], different densification mechanisms [73,74], different binder fraction [75] and different sintering temperature [76]. Meanwhile, the existing literature mainly considers the alteration of GBCD under plastic deformation [77][78][79][80][81].…”

This paper reports the interdisciplinary approach of simultaneous use of a stereological method, namely the five parameter analysis (FPA) method and the grain boundary character distribution (GBCD) in cemented carbides. There are six major aspects: i) the background and motivations of the interdisciplinary approach, ii) the principle of the FPA method, iii) orientation texture of boundary planes with specific misorientations via ?(?g, n) mode in cemented carbide, iv) orientation texture of habit planes regardless of misorientations via ?(n) mode in cemented carbide, v) application of the FPA method to serial cemented carbide samples and vi) boundary sort methods before using the FPA method. The work aims at presenting beneficial reference for studying structural and distribution features of special coincidence site lattice (CSL) boundaries in a statistical manner, and in turn increasing the knowledge about the structure-property relationship in cemented carbides.

“…Among all transition metal carbides, the rigidity of WC is biggest, and the grain shape of WC is polygonal to prevent cracks penetrating effectively [10,[13][14]. Previous studies have shown that WC additive in TiC and TiNC cermets with nickel as binder can improve the toughness and refine the grains of the alloy [9,[15][16][17].…”

TiC base high manganese steel-bonded carbide was manufactured by powder metallurgy technique, and the effect of adding mode of WC additive on microstructural evolution and properties of the alloy was studied. SEM microstructure showed that surrounding structure appeared obviousely with WC additive; while microstructure of the alloy was well-distributed and particle shape was distinct very much. The shape of TiC particles became irregular with pure WC powder addition, and irregular with further increase of WC content, and the shape of some TiC particles became angular because of excessive reaction between TiC particles and WC additive. microstructure of the alloy was refiner and the strength, toughness were improved with the increase of WC addition. (Ti, W)C solid solution is superior to form on the surface of TiC particles through dissolution precipitation mechanism because the activity energy of WC was higher than that of TiC-WC compound carbides when WC was added in the alloy, and the particle shape of TiC became more irregular and the properties were improved significantly.

“…Engineering materials must be designed and manufactured in accordance with the application conditions to embody the properties of the materials extremely [9][10]. Of all the transition metal carbides, WC has the largest stiffness and the grain shape is polygonal, which has an important effect on preventing crack propagation [9,[11][12]. Previous works have shown that WC can be added to improve the toughness and grain refinement in sintering TiC and TiCN using Ni as the binder [13][14][15][16].…”

TiC base high manganese steel-bonded carbide was manufactured with conventional powder metallurgy method to service in wear and impact resistant condition. WC was added in the alloy in the form of (W,Ti)C carbides to improve the impact toughness and expand the applications of alloy, meanwhile, cobalt powder was also used to enhance the wettability of the metallic binder on the ceramic phase. Results showed that the impact toughness of the alloy was increased remarkably with the increase of WC content. The impact toughness reached 10.6 J/cm2 when WC content was 10.5 wt.%, while the hardness of the alloy did not decrease. It was indicated that the appropriate content of WC and cobalt can improve impact toughness and wear resistance of the alloy greatly with little increase in the production cost.
