Cover Story: This work highlights reactive sintering as an innovative and sustainable method for producing cemented carbides, avoiding the expensive process of carburizing tungsten in hydrogen. A mixture of tungsten, carbon, and Cr3C2-doped cobalt powders was milled and sintered at 1450 °C under vacuum, resulting in complete WC formation. The microstructure is fine and uniform (0.32 µm grains) with promising mechanical properties: 92% densification, 1800 HV30 hardness, and 10.9 MPa·m¹⁄₂ toughness. These findings show that high-performance cemented carbides can be made through a simpler, greener process. Remaining issues include porosity and traces of brittle eta phase, which require optimizing powder processing and pressure-assisted sintering. This method opens a path for industrial applications that combine efficiency, performance, and sustainability. View this paper
