“…In another study, [54] the role of high chromium cast iron powder in order to achieve WC -10-30% cast iron (Fe-27Cr-3.1C) cemented carbides is described. Figure 7 shows the effect of sintering temperature (1500-1900*K) on the relative density.…”

“…Hinners et al prepared hardfacing where WC and MxCy particles were embedded in Fe(Cr) matrix [8]. Sakaguchi et al and Kambakas et al focus on the high chromium grey cast irons with WC reinforcement [9,10]. Our studies of the FeCr binder system have shown that it is challenging to achieve a uniform structure without using very fast consolidation processes (e.g.…”

High price, limited availability and toxicity of cobalt motivates researchers and material engineers to find alternative binder systems for WC cemented carbides. Iron and iron alloys are promising candidates for complete cobalt substitution. Ferritic steels alloyed with chromium can offer an inexpensive binder system to acquire cemented carbides with enhanced oxidation and corrosion resistance. Since Fe and Cr are carbide formers, production of WC-FeCr cemented carbides with a desirable two-phase structure can be problematic. Niobium and titanium are strong carbide formers and well-known alloying elements in steels used to stabilize carbon, preventing formation of unwanted chromium carbide phases. In our work, WC-FeCr was alloyed with elemental Nb and Ti. The phase composition, structure morphology and mechanical properties of prepared cemented carbides were characterized and discussed. As a result, additions of carbon stabilizing elements enabled us to improve structural homogeneity and wear resistance of WC cemented carbides with ferritic a steel binder.
