“…They reported that a lower amount of the Cr 7 C 3 phase (0%-14%) shows low hardness (4.7-5.5 GPa), whereas an increase above 17% resulted in values above 6 GPa. Similarly, hardness of the Cr 3 C 2 carbide phase was reported between 15.1-18.9 GPa, which was correlated with the grain size of the corresponding phase [58]. Therefore, quantification of the phases through the Rietveld refinement would be a preferable method for correlating phases and mechanical properties.…”

“…It should be noted that it is possible, as well, to synthesize the metastable chromium carbides like CrC and Cr 3 C, which is confirmed, inter alia, by authors of works [11,12]. According to Hirota et al [13] Due to the high hardness of chromium carbides and relatively low price of chromium, they are also used as a strengthening phase in nickel based superalloys and cobalt based alloys (Stellites), performing in many cases with the MC carbides (M = Nb, Zr, Ta, Hf) [15÷24]. In the iron based alloys, chromium carbides are used in tool steels and hardfacing alloys as well [1÷6,22,23].…”
