Consolidation of binderless WC–TiC by high frequency induction heating sintering

Microstructure and mechanical properties of WC– x at.% TiC ( x = 0–50) cemented carbides fabricated by high-frequency induction heating sintering (HFIHS) method were investigated. The densification of binderless WC–TiC was accomplished using ultra fine powders of WC and TiC. Nearly fully dense hard...

Summary:Microstructure and mechanical properties of WC– x at.% TiC ( x = 0–50) cemented carbides fabricated by high-frequency induction heating sintering (HFIHS) method were investigated. The densification of binderless WC–TiC was accomplished using ultra fine powders of WC and TiC. Nearly fully dense hard materials with a relative density of up to 98.5% could be obtained with simultaneous application of 60 MPa pressure and induced current within 2 min without significant change in grain size. The average grain size of WC produced by HFIHS was about 200 nm. The hardness and fracture toughness of the dense WC–TiC cermets produced by rapid sintering process were investigated.
