“…Furthermore, the yield strength of Ni 3 Al increases substantially with increasing temperature up to 600-800°C [14,15]. In addition, the Ni 3 Al phase was found to have a good wettability with WC grains, making it possible to obtain dense bulk WC-Ni 3 Al [16][17][18]. Ni 3 Al is therefore a specially promising material needed in aggressive environment at elevated temperature.…”

“…The dissolved WC particles re-precipitated on the surface of the larger undissolved WC particles, which promoted the growth of WC grains. Since both Co and Ni 3 Al can dissolve a certain amount of WC near the sintering temperature [18], the same mechanism should occur in WC-Ni 3 Al system. In addition, the results show that the sintered samples are both composed of WC and Ni 3 Al.…”

In this paper, WC-10Ni3Al cemented carbides were prepared by the powder metallurgy method, and the effects of ball-milling powders with two different organic solvents on the microstructure and mechanical properties of cemented carbides were studied. We show that the oxygen in the organic solvent can be absorbed into the mixed powders by ball-milling when ethanol (CH3CH2OH) is used as a ball-milling suspension. This oxygen leads to the formation of α-Al2O3 during sintering, which improves the fracture toughness, due to crack deflection and bridging, while the formation of η-phase (Ni3W3C) inhibits the grain growth and increases the hardness. Alternatively, samples milled using cyclohexane (C6H12) showed grain growth during processing, which led to a decrease in hardness. Therefore, the increase of oxygen content from using organic solvents during milling improves the properties of WC-Ni3Al composites. The growth of WC grains can be inhibited and the hardness can be improved without loss of toughness by self-generating α-Al2O3 and η-phase (Ni3W3C).

“…The increased oxygen concentration (Figure 11d) and presence of carbide inhibitors (Figure 11e) during LPS made the WC grains even more rounded.

“…It appears that the WC grains surrounded by the Al0.5CoCrCuFeNi HEA binder are slightly more faceted than those surrounded by the equimolar CoCrCuFeNi HEA binder and Al2CoCrCuFeNi HEA binder with aluminum (see Figure 12). This result means that the faceting-roughening transition takes place at the WC/binder interfaces if one substitutes the simple cobalt-based binder using the HEA- Minor changes in shape of WC crystallites were also observed through the substitution of cobalt binder in WC-based cemented carbides using Fe [66][67][68], Ni [69][70][71][72][73][74], Al [75,76], Fe-Mn [77][78][79][80][81][82], Fe-Cu [83], Fe-Ni-Mo [84], Ni 3 Al [85][86][87][88][89][90][91][92], Ni-Cr [93], Y 2 O 3 [94], Al 2 O 3 [85,95,96], Ni, CoNi, NiCr, CoCr, CoNiCr, NiCrMo [97], MgO [98,99], ZrO 2 [100][101][102], La 2 O 3 [103,104], iron aluminides [65,[105]…”

Hardmetals (or cemented carbides) were invented a hundred years ago and became one of the most important materials in engineering. The unique conjunction of fracture toughness, abrasion resistance and hardness makes WC-Co cemented carbides irreplaceable for numerous applications. As a rule, the WC crystallites in the sintered WC-Co hardmetals are perfectly faceted and possess a truncated trigonal prism shape. However, the so-called faceting–roughening phase transition can force the flat (faceted) surfaces or interfaces to become curved. In this review, we analyze how different factors can influence the (faceted) shape of WC crystallites in the cemented carbides. Among these factors are the modification of fabrication parameters of usual WC-Co cemented carbides; alloying of conventional cobalt binder using various metals; alloying of cobalt binder using nitrides, borides, carbides, silicides, oxides; and substitution of cobalt with other binders, including high entropy alloys (HEAs). The faceting–roughening phase transition of WC/binder interfaces and its influence on the properties of cemented carbides is also discussed. In particular, the increase in the hardness and fracture toughness of cemented carbides correlates with transition of WC crystallites from a faceted to a rounded shape.
