Abstract The WC-6Co cemented carbides were sintered using hot oscillating pressing (HOP) method. The interplay of sintering parameters between microstructure and mechanical properties were systematically investigated. Results revealed that HOP could enhance the densification, restrain grain growth, shorten Co matrix average free path, and accelerate Co distribution in WC-6Co cemented carbides, which improved the combined performance for hardness of 25.22 Gpa and fracture toughness of 12.89 MPa·m1/2 after sintering at 1400 °C. It is worth emphasizing that these mechanical properties are better than similar cemented carbides prepared by conventional methods, indicating the promise of utilizing HOP for high-performance cemented carbides.
